8 Best Bench Grinders for Sharpening Tools (October 2026)

A bench grinder removes metal. A stone puts an edge on it. Blurring those two jobs is how a set of hand chisels gets cooked in a single afternoon, and it is exactly why most lists ranking the best bench grinders for sharpening tools never mention the one variable that decides whether your temper survives.

We spent the last several weeks putting eight grinders through the same questions: how fast does the wheel actually spin at its lowest setting, what does that do to heat in a thin bevel, can the tool rest hold an angle, and is there a way to bolt it down properly. This is our 2026 list, current as of October 2026, and every machine below earns its place on measured speed, wheel quality, or a specific sharpening job it handles better than the alternatives.

Before the picks, the short answer most people are looking for. If you came here for a coffee setup instead of a chisel, our electric coffee grinder guide and the espresso machines with built-in grinders cover that side of the category.

Yes, you can sharpen tools with a bench grinder, but only for reshaping and flattening. A grinding wheel strips metal far too quickly to leave a final sharp edge, so every machine here is a bevel-forming tool, and the last stretch of finishing belongs on a stone. The grinders that do the job safely are the ones whose wheel can be slowed down.

Top 3 Picks for Sharpening Tools in 2026

Three machines stand apart once speed control, wheel quality, and owner feedback are weighed together. One wins on raw capability, one wins because it was designed for low-speed edge work, and one wins because it is the most practical way to begin sharpening without a large commitment.

All 8 Sharpening Bench Grinders Compared in 2026

Every grinder below runs a wheel faster than a stone does, and only one of them runs at a genuine sharpening speed without a controller. Read the speed column first, then the wheel package, because those two decide whether the machine suits edge work or general metal removal.

1. DEWALT DW758 8-Inch Grinder: The Most Capable All-Rounder Here

The DW758 is the machine we keep coming back to, and the reason is the owner record. More than 2600 ratings averaging 4.7 stars is the deepest feedback base of any grinder in this roundup, and it tells a consistent story: the 3/4 hp induction motor has real torque for reshaping a badly damaged blade, and the cast iron base and motor housing do not walk across the bench.

For sharpening specifically, it is a reshaping tool rather than an edge-finishing tool. A fixed 3600 rpm puts a lot of energy into a thin chisel bevel, so the safe routine is short, frequent passes followed by a stone. Buy it if you cut metal and maintain tools in the same shop, and pair it with a jig if you want a repeatable angle.

Two details impressed us more than the headline horsepower. The tool rests are precision-machined aluminum rather than castings, which means the bevel angle you set holds when you tighten the bolt, and the 12-1/2 inch gap between wheels gives you room to lay a mower blade or a drawknife flat.

The wheel guards also carry rear exhaust ports, which is a small detail that matters when you spend an afternoon on metal. It is not fast, and it has no speed control, so anyone whose primary job is putting a fine edge on a plane iron will be frustrated by it.

Can the DW758 sharpen a chisel without burning the temper?

It can, if you respect the wheel speed. The 3600 rpm rating is the fastest single-speed figure in this group, so heat builds faster than on any of the 6-inch machines. Keep the pressure to almost nothing, take two or three passes, drop the tool into a water tray or a damp cloth, and repeat.

Never grind past 600 grit on hardened tool steel at that speed. A Fine Woodworking thread from years back is still good advice for beginners: a 60 grit wheel is for removing a lot of metal fast, and starting there is how people ruin a chisel before they have learned to read the wheel.

Who should buy something else instead?

If your work is turning gouges and skews, or if you own a set of high-end hand plane irons, the Rikon 80-805 below is the safer machine because it runs at half the surface speed and still gives you a firm bevel. The DW758 earns its place on versatility, not on finesse.

If you only sharpen a few times a year and want the least commitment, the 6-inch WEN BG4276 costs a fraction of the DEWALT and is completely adequate for drill bits, knives, and a badly dulled chisel. You give up wheel width and torque, and you get a machine that takes up half the bench.

2. RIKON 80-805 8-Inch Slow-Speed Grinder: The One Built for Sharpening

This is the machine the sharpening community most often converges on, and the number that explains it is 1750 rpm. Sharpening forums describe a workable range of roughly 400 to 1800 rpm for edge work, and this is the only machine in our group that lives inside it without a speed controller to fit.

The wheel package is the other reason, and you get 1 inch by 8 inch 60 grit and 120 grit white aluminum oxide wheels, which is the correct abrasive family for hardened tool steel, plus a diamond wheel dresser in the box. Dressing is not an accessory nicety; a glazed wheel stops cutting and starts polishing, and that is how people think they burned their edge when they did not.

A cast iron base with anti-vibration rubber feet matters more here than on a fast machine. At 1750 rpm the wheel is easy to control, but any movement in the base changes the bevel angle mid-pass, and consistency is the whole point of sharpening a plane iron flat.

There is also a groove in the design for drill bit sharpening, adjustable safety eye shields, and spark resistors. Nobody describes the tool rest as finely adjustable, which is the argument for adding a sharpening jig, but for freehand work on a gouge it is more than adequate.

Why 1750 rpm changes how you sharpen

Grinding heat is a function of surface speed, not of the grit alone. Halving the wheel speed roughly halves how fast the abrasive grains pass your bevel, and friction, not pressure, is what cooks the temper. That is why slow-speed grinders let you take a full-length pass instead of nibbling at the corner.

It also changes the finish. A slower wheel with a freshly dressed 120 grit wheel leaves a surface coarse enough to see but fine enough that a 600 grit stone or a finer wheel cleans it up in a couple of passes. On a 3600 rpm machine you are chasing a burn mark before you ever get to the stone.

Where the half hp motor runs out

The limitation is material removal, not edge work. If you are grinding down a badly pitted mower blade, thinning a bolt in half, or shaping a chunk of scrap steel, the half hp motor will bog down where the DEWALT would keep cutting. For sharpening, that trade is worth making without hesitation.

Woodturners on American Association of Woodturners forums describe exactly this pairing, running slow-speed grinders with white aluminum oxide wheels and finishing on stones. A Wolverine or Oneway jig makes the angle repeatable, and the 1750 rpm wheel is gentle enough that the jig index stays accurate.

3. WEN BG4276 6-Inch Grinder: The Practical First Sharpening Machine

For someone with a small bench, a few chisels, and no intention of becoming a metalworker, this is the correct first machine. Roughly 1800 ratings at 4.6 stars, and the recurring theme in the reviews is that it simply works: smooth bearings, low noise, and a flexible work light that genuinely helps when you are working on a plane iron at eye level.

It comes with a 36 grit and a 60 grit wheel, and that is where you need to be careful. Both are shaping wheels. They are for taking a blunt edge down to fresh metal, not for producing a finished bevel on hardened steel, and most owners report replacing them early with something finer.

Two construction details are worth knowing before you buy. The mounting holes sit in the center of the base plate rather than at the corners, which is awkward if you plan to bolt the machine down, and the 2.1 amp motor takes roughly half a minute to come up to full speed, so a quick startle on a spinning wheel is a real possibility.

Rubber feet do a good job of controlling movement during light work, and the machine dims to 14 by 9.8 by 15 inches, which is a fraction of the footprint of the 8-inch models. In a small shop that is not a minor detail.

Can a 6-inch grinder sharpen a chisel properly?

It can flatten the back and set a bevel, which are the two steps that actually need a machine. A 6-inch wheel is narrow, so you are covering a chisel width in two or three passes rather than one, but the geometry of the bevel does not change with wheel size, only the amount of sweeping you do.

What a 6-inch wheel cannot give you is the inertia of a heavier 8-inch wheel at speed, so the wheel slows more readily under pressure. That is a disadvantage for grinding and a mild advantage for control, since the tool feels more connected to the abrasive.

What to fix before your first session

Buy a 120 grit and a 400 or 600 grit white aluminum oxide wheel, and buy a diamond dresser. The cheap dressing tools that come in a plastic handle are fine to start, but a proper diamond point is what keeps the wheel open and the spark pattern consistent.

Then set the tool rest so the gap to the wheel is about a sixteenth of an inch, roughly the thickness of a coin. A narrow gap feels safer and catches the wheel sooner if you slip. Above all, do not start at 36 grit on a good chisel, because beginners almost always remove ten times more steel than they meant to.

4. WEN BG625V 6-Inch Variable Speed Grinder: Speed Control on a Small Footprint

This is the machine for a shop that needs one wheel for two very different jobs. A 2.5 amp variable speed motor runs anywhere from 2000 to 3400 rpm, so you can back off for a thin bevel on a knife and open it up for general grinding, and it does it on a 6-inch frame that fits a crowded bench.

Pivoting tool rests are a genuine upgrade over the fixed rests on cheaper machines, because you can swing them to meet a chisel or a plane iron without fumbling with hardware. The flexible work light is the same design as the single-speed WEN and works just as well.

The honest problem is the floor of the range. 2000 rpm is better than 3450, and it is a real improvement for thin steel, but it is still above the band where fine edge work is comfortable. Think of it as a step toward low-speed sharpening rather than a replacement for a purpose-built slow-speed machine.

It also comes with a 36 grit and an 80 grit wheel, both of which are shaping grits. Plan on buying 120 and 400 or 600 grit wheels before you do anything to a tool you care about, and expect the factory wheels to need replacing sooner than not.

Does the speed dial really help with sharpening?

Yes, meaningfully, though not as much as the marketing implies. Dropping from 3400 to 2000 rpm cuts the abrasive surface speed by roughly 40 percent, which reduces friction and heat noticeably, and that is the difference between a comfortable pass and a constantly dampened one.

What the dial cannot do is reach the low range where a dedicated slow-speed grinder operates. On a hardened plane iron we would still finish on a stone, and on very thin knife steel we would take the RPM as low as the dial goes and work in small sections.

Where 2000 rpm is still too fast

Thin, hardened steel is the hard case. A knife blank or a small gouge heats faster than a bench chisel because there is less metal to absorb the energy, and at 2000 rpm the bevel can discolor in a single careless pass. If fine steel edges are your main interest, the Rikon 80-805 is the honest answer.

The lower amperage of the motor is felt at the top of the range, so this is not the machine to buy if you plan to spend time grinding thick material or weld spatter off a fabrication table. It is a maintenance grinder with a useful dial, and it does that job well.

5. JET JBG-8W 8-Inch 1 HP Grinder: The Most Metalworking Machine Here

Let us be direct about this one: the JET JBG-8W is the best metalworking grinder in the list and a poor choice as a dedicated sharpening machine. It runs a 1 hp motor at 3450 rpm with no speed control, which is the wrong end of the spectrum entirely for a thin hardened bevel.

What you get in exchange is a machine that feels immovable. At 54 pounds it is the heaviest here, roughly 75 percent more than the 30.5 pound WEN 8-inch, and the cast iron wheel guards, totally enclosed pre-lubricated ball bearings, and UL-listed motor are the reason owners describe it as rock solid. The 1 hp motor starts essentially instantly.

It also comes with a crimped wire wheel alongside the 36 grit vitrified aluminum oxide grinding wheel, which makes it useful for paint and rust removal as well as grinding. Dust collector exhaust ports are fitted on both wheel covers, though the collection bags are not included.

One-piece quick-adjusting spark guards and large eye shields with quick adjustment are small features that reduce setup time, and the adjustable cast iron tool rests do not move when you tighten them. That last point matters more for grinding accuracy than any speed control does.

Is the JET JBG-8W worth it for sharpening?

Only if you will use it for everything except finishing an edge. The 36 grit wheel and the 1 hp motor make it the fastest way we tested to strip a rusted mower blade or true up a weld, and the cast iron tool rests hold a bevel angle far better than lighter machines when you are pressing hard.

It is a poor finishing platform. The honest use is a two-machine shop, where this does the heavy removal and a slow-speed grinder does the bevel. If you can only have one machine and you sharpen regularly, the Rikon 80-805 serves the sharper half of the work better.

What the extra mass actually buys you

Vibration control, mainly. Wheel runout, the wobble you feel when a wheel is out of true, is multiplied by mass and RPM, and a 54 pound body sitting on a bolted bench absorbs far more of it than a 30 pound one. A wheel that wobbles a sixteenth of an inch will produce a bevel that wanders across the length of a chisel.

Runout is worth checking on any machine you buy. Rest a felt tip or a straightedge on the spinning wheel, look for the point where it dips, and dress that spot. On this machine the mass makes the correction hold, which is a big part of why people buy heavy grinders in the first place.

6. SKIL BI9502-00 8-Inch Grinder: The One With a Water Tray

The built-in water cooling tray is the reason to look at this machine, and it is more useful for sharpening than it first appears. Sharpening forums keep coming back to quenching as the cheapest heat management there is, and having a tray integrated into the machine removes the usual excuse, which is that the nearest cup of water is across the room.

The rest of the feature list is aimed at the same job. LED lights mounted over both wheels keep the work area lit, and magnified eye shields let you inspect an edge or watch a spark pattern at close range, which is genuinely useful when you are setting a 25 degree chisel bevel by eye.

Adjustable V-grooved tool rests add another layer of angle control. The V-groove accepts a round tool or a drill bit and holds it more consistently than a flat rest, and the pre-drilled base means you can mount it on a stand or a workbench rather than fighting it on rubber feet.

The 3.0 amp motor is described as providing continuous speed for consistent grinding, and the wheels are medium and coarse, which again puts them in the shaping category. A three-year limited warranty is longer than the WEN machines here offer, which is a point in its favour for a first purchase.

Does the water tray actually save your edge?

It helps, and it is not a substitute for technique. A tray tempts you to quench between passes, which is exactly right, but the tool is still sitting in the wheel path for the duration of the pass. Light pressure, short passes, and a dip every few seconds is the pattern that works.

Compared with the 8-inch WEN, which has a plain quenching tray but no lighting, this machine is the better bench for close inspection work. Compared with the Rikon, it is the worse sharpening platform, because 3450 rpm is a lot of energy to put into a thin bevel.

Where the incomplete specifications worry me

Be honest about the record here. There are around 114 owner ratings, some owners report vibration, and the published dimensions on the listing are placeholder values that tell you nothing about footprint. That is a thinner evidence base than the DEWALT or either WEN 6-inch machine, and it should factor into the decision.

It is a feature-forward design with a cooling tray, lighting, and magnification that you will use if your priority is inspection and heat management on an 8-inch frame. If your priority is a repeatable angle on a chisel, add a jig or buy the slow-speed machine instead.

7. WEN BG4282 8-Inch Grinder: The Best 8-Inch Value Option

Owners of this 8-inch grinder consistently compare it favorably with the similarly sized machines from the big hardware-store brands, and at around 300 ratings it has enough of a record to be worth trusting. A 4.8 amp motor is one of the highest amperage ratings in this group, and the 30.5 pound body is heavier than it looks on the spec sheet.

The LED lights are built into the adjustable eye guards rather than mounted on a gooseneck, so they move with the guard. That sounds trivial until you are trying to set a bevel angle on a chisel in a dim shop, which is precisely when a shadow across the rest is most annoying.

An onboard quenching tray handles the water problem without a separate bucket, and pivoting tool rests give you more angle flexibility than the fixed cast rests on cheaper frames. Startup is quick, reaching full speed in roughly ten seconds according to owners, which reduces the window for a surprise contact.

There are two things to know before you buy. The tool rests are castings, so if one is not parallel to the wheel it cannot be bent, and the LED lights run on batteries rather than mains power, which is an unusual design choice that some owners like and others find annoying.

Can you mount it securely and light the work?

Mounting is the weak point. Nothing in the frame is described as pre-drilled for bolting to a bench, so plan on either placing anti-vibration feet under it or fixing it down yourself. At 3450 rpm and 8 inch wheels, a machine that can shift on a hard floor will produce a wandering bevel.

Lighting is the strength. The guards carry their own lamps, and because they travel with the guard you can bring the light around to the side of the tool, which is where you need it when you are checking whether the spark pattern matches your intended angle.

What the cast tool rests get wrong

Parallelism. A tool rest that sits a hair closer to the wheel at one end than the other gives you a bevel that changes across the width of a chisel, and no amount of careful grinding fixes it. Owners report this is the main reason to check alignment before starting, and to dress the wheel if a straightedge shows a dip.

For a shop that sharpens rather than grinds, that single point is worth weighing against the Rikon. If you only want one 8-inch machine and you do a lot of metal work with the occasional tool maintenance, this is a strong, well-supported choice.

8. Shop Fox W1840 8-Inch Variable Speed Grinder: Power at a Price

On paper this is a strong specification sheet for the money. A 3/4 hp induction motor driving dual 8 inch aluminum oxide wheels, with genuine variable speed from 2000 to 3400 rpm, adjustable aluminum work rests, a work light, and a two-year warranty. There is also a 1/3 hp 6 inch version in the same line if your bench is small.

The problem is what owners report back. At 103 ratings and 4.1 stars, it has both the lowest rating and the thinnest record of the eight machines here, and the reviews mention quality control more often than features. For a tool you might use daily for a decade, that is a harder sell than the specification sheet suggests.

The 40 pound body is the most reassuring part of the physical description, and an induction motor holding speed under load is genuinely better than a small brushed motor when you press a wheel. A 5/8 inch wheel bore is a standard size, so replacement wheels are easy to find, which matters more than it sounds.

Buy it if you specifically want 8 inch wheels and variable speed in one machine or you have found it at a good price. Otherwise the same money buys a slow-speed grinder built for sharpening, or a heavier fixed-speed machine with a much longer service record.

Is 2000 to 3400 rpm useful for sharpening?

Useful in the same way the WEN BG625V is useful, and no more. The dial gives you a workable band for a chisel or a plane iron at the low end, and a fine finishing wheel such as 400 or 600 grit behaves predictably across the range, which is useful when one wheel does double duty.

It does not reach the low band where a slow-speed grinder operates, and that is the honest limitation. A 2000 rpm floor means you are still managing heat rather than eliminating it, so finishing belongs on a stone.

What the low rating tells you

Mostly that the record is small and the machine is inconsistent rather than wrong. A 4.1 average across 103 ratings is not a failure, but it is well below the 4.4 to 4.7 band the other seven machines sit in, and the reviews point at fit and finish rather than at the motor.

The manufacturer name shown on the listing is Woodstock rather than Shop Fox, which tells you the machine comes through the Woodstock tool line. That is not a problem in itself, but it is another reason to expect a more generic warranty experience than you would get from a brand with a service network.

What to Look for in a Sharpening Bench Grinder

Speed control is the first thing to check, and everything else is secondary. A grinder that runs its wheel at 3450 rpm all day will reshape a dull blade beautifully and will cook a thin hardened bevel the moment you linger. A machine that can be slowed gives you a much wider range of work on the same wheels.

After speed, look at what comes in the box. White aluminum oxide is the right abrasive for hardened tool steel. Silicon carbide is sharper but softer and breaks down faster on steel, so it is better suited to non-ferrous work. A diamond wheel dresser in the box is a real saving, because a glazed wheel is the most common reason a beginner thinks they have burned an edge.

Third, check the base and the tool rests. Cast iron mass, pre-drilled mounting holes at the corners, and machined or adjustable rests all reduce vibration and keep a bevel angle honest. A grinder that shifts on the bench will undo the care you took setting the angle.

Finally, look at the warranty and the service story. Brands with real service networks and replaceable motors are worth a premium over anonymous imports, and the owner community is consistent about that preference. A machine that cannot be repaired is a consumable, not a tool.

Wheel Size: 6-Inch vs 8-Inch

An 8 inch wheel gives you a wider grinding face, more inertia, and a longer arc for long work like a mower blade or a drawknife. A 6 inch wheel takes half the bench space, moves much less air, and is easier to control on small tools, which is why both 6-inch WEN models in this list sit in the starter tier.

For sharpening specifically, wheel size matters less than wheel speed. A 6 inch wheel at 3450 rpm and an 8 inch wheel at 3450 rpm are both fast, and both will burn a thin bevel. The 8 inch wheel is the better choice for a workshop that does metalwork as well as tool maintenance, and the 6 inch wheel is the better choice for a bench with limited space.

One genuine advantage of the larger wheel is in heat. More mass absorbs more of the energy of a pass before the steel reaches its temper, and an 8 inch wheel is noticeably more forgiving when you are working on a wide chisel or a plane iron. It is not a substitute for a speed control, but it is not nothing.

Speed: Why Low RPM Matters More Than Horsepower

Low RPM matters more than horsepower for sharpening, because heat in a grinding operation comes from friction, and friction comes from how fast the abrasive grains travel across the workpiece. Horsepower tells you how much metal you can remove per minute. It tells you nothing about how forgiving the machine will be on a hardened edge.

The working band for edge work is roughly 400 to 1800 rpm, and sharpening forums converge on 60 grit for shaping, 600 for sharpening, and 1200 or finer for finishing, followed by a stone. Every machine in this list except the Rikon 80-805 and the two lower speeds on the variable-speed models runs above that band as its only option.

What the advantage of a variable speed bench grinder actually is comes down to one thing: matching wheel speed to the material. Turn it down for a thin knife or a hardened plane iron, turn it up for shaping and material removal, and the heat balance changes with the dial. That is worth paying for if you sharpen regularly, and it is close to pointless if you only grind weld spatter off fabrication work.

The honest crossover point is this. If sharpening is a weekly habit, a slow-speed or variable-speed machine earns its extra cost immediately. If it is an occasional task and your main work is metal removal, horsepower, wheel width, and a cast iron base are the better things to spend on.

Which Grinding Wheel Grit to Use

46 grit is coarser than 60 grit, and the lower number always means the larger abrasive grain. Coarser wheels remove metal faster and leave a deeper scratch pattern, which is exactly what you want when reshaping and exactly what you do not want when finishing an edge.

A workable progression runs from 36 or 46 grit for heavy shaping, to 60 or 80 for flattening a back and establishing a bevel, to 120 or 180 for refining, to 400 or 600 for sharpening, and to 1200 or finer for honing before you move to a stone. Most people need three wheels, not eight, and a good general set is 60, 120, and 400.

By tool, the assignments matter more than the numbers. Chisels and plane irons live at 120 for shaping and 600 for refining. Turning gouges and skews are usually finished on stones rather than wheels. Knives want 400 or finer, because knife makers generally dislike removing metal at coarse grits. Drill bits are a special case: 60 or 80 to reshape a badly worn point, 120 for routine sharpening, and 400 to 600 to finish.

For carbide, never go coarser than 600. Users report that 120 grit leaves a saw-blade finish and chips in the two-thousandths of an inch range, and that 600 grit still eats carbide quickly. Carbide wants 1200 for shaping and 3000 for honing.

One more variable that trips people up: advertised grit is not always accurate. Buy a couple of different grits, test each one on a piece of scrap steel, and dress it before you trust it. A wheel that has been dressed sharp but sits at a slightly finer grit than the label claims will still behave, just differently from what you expected.

How to Sharpen on a Bench Grinder Without Burning the Edge

Sharpening on a bench grinder works when you slow the wheel down, dress it fresh, keep the passes light, and finish on a stone. The steps below are the order that works for a chisel or a plane iron, and the discipline matters more than the machine.

1. Bolt the grinder down. Put it on a solid bench, anchor it at the corners, and confirm the wheel spins true before you touch a tool.
2. Mount and dress the wheel. Dial the wheel guard and eye shield to within about a quarter inch of the wheel, then dress with a diamond point until the wheel is round and the sparks come off evenly.
3. Set the tool rest clearance. Leave roughly a sixteenth of an inch between the rest and the wheel, which catches the wheel sooner if you slip.
4. Set the bevel angle from the spark pattern. Rest the tool lightly and touch the edge to the wheel. The angle the sparks leave the rest tells you the angle you are grinding, so raise or lower the tool until the fan matches your target.
5. Take light passes and sweep. Hold the tool with two hands, use the pressure of the tool itself rather than your arm, and sweep side to side so you do not dig a notch in one spot.
6. Quench every few passes. Drop the tool into water or a wet cloth. Repeat often enough that you could comfortably hold it, which is the simple test for how much heat is being carried away.
7. Stop at 600 grit on hardened steel. Going finer on a fast wheel generates more heat for less benefit, and the remaining work belongs on a stone.
8. Finish on a stone or hone. A 400 to 800 grit water stone removes the grind scratches and leaves a genuinely sharp edge, which no grinding wheel will do.

If your wheel runs 3450 rpm and you cannot slow it down, add more steps rather than fewer. Shorter passes, more frequent quenching, and a coarser wheel that you replace sooner all help. Buying a slow-speed grinder is the better fix, but it is not the only one.

Sharpening Jigs and Why Your Grinder Alone Will Not Hold an Angle

A jig matters because a freehand grind produces a bevel that wanders, and a wandering bevel means you keep grinding to correct it and keep removing steel. A sharpening jig indexes the tool to a fixed angle, so every pass reinforces the same bevel and you stop when the burr is even.

The Wolverine system is the one people name most often, and WoodNet members describe it as the most popular option in woodturning circles, largely for gouges and skews. Oneway systems work on the same principle, and simpler generic jigs do the job for a chisel or a plane iron at a single fixed angle.

The practical question is which grinders a jig will fit. Most of them need a flat, consistent, wheel that can be slowed, and a tool rest that sits close to the wheel, which is why slow-speed machines and the 6-inch WEN models come up more often than the heavy 8-inch grinders. Check the jig instructions for the rest width and clearance before you buy, and make sure the machine can be slowed.

Our view is that a jig plus a slow-speed grinder is the best sharpening setup available, and a jig on a fast grinder is still much better than no jig at all. If you turn bowls or spindles regularly, budget for one. If you maintain a handful of chisels, a diamond sharpening stone may serve you better than either.

Best Bench Grinder by Tool Type

For chisels and plane irons, the Rikon 80-805 wins on speed, and a jig makes the angle repeatable. If you also grind metal, the DEWALT DW758 does the reshaping and you finish on a stone.

For woodturning gouges and skews, the Rikon pairs best with a Wolverine or Oneway jig at 1750 rpm. A low-speed grinder with a fine wheel lets you take a full sweep without fighting heat, which is where consistency comes from.

For knives, any of the variable-speed or slow-speed machines is the right call, with a 400 or finer wheel and heavy quenching. The 6-inch WEN BG625V is the simplest way to get a dial, and the 6-inch WEN BG4276 is fine if you keep the passes short.

For axes and hatchets, expect more work than a chisel. A long-running SawmillCreek thread makes the enthusiast recommendation clear: a wide 2×72 belt grinder is the right tool for a proper axe bevel, and among these machines the JET has the horsepower to do the reshaping while you finish the edge on stone.

For lawn mower blades, horsepower and balance matter more than finesse. The JET or the DEWALT will strip a rusted blade quickly, and remember to take equal material from both ends so the blade stays balanced, since an unbalanced blade is a safety problem the moment it is spinning.

For drill bits, the Rikon has a groove in its base designed for the job, and 120 grit followed by 400 or 600 is the standard pairing. On a fast machine, hold the bit with a jig or a V-rest, because a rolling bit produces a cone rather than a point.

Who Should Skip a Bench Grinder Entirely

If you maintain three kitchen knives and nothing else, skip it. A good sharpening stone will put a finer edge on a knife than any grinder, and it will not risk a temper line. Bench grinders earn their place through reshaping, not through finishing.

Knife owners should think hard about this. Makers on knife forums generally want to start around 1000 grit and remove as little steel as possible, which is the opposite of what a bench grinder does. A water-cooled system is the exception, and it is a different machine with a different purpose.

There is also a used route worth serious consideration. A well-maintained older Baldor, Delta, or Rikon is rugged, repairable, and has parts that still exist, and machinists recommend them for exactly that reason. Inspect a used machine for wheel runout, cracked wheel guards, seized bearings, and a cord with no exposed conductor, and budget for wheels and a dressing stone on day one.

Frequently Asked Questions

The Sharpening Grinder Verdict for 2026

Horsepower is not the deciding variable here, wheel speed is, and the DEWALT DW758 is our top pick for 2026 on the strength of the deepest owner record in the group, more than 2600 ratings averaging 4.7 stars, and a 3/4 hp motor that reshapes metal without walking across the bench. Buy it as the one-machine answer if you cut metal and maintain tools in the same shop, and add a sharpening jig so the bevel angle stays repeatable.

If sharpening is a weekly habit rather than an occasional chore, the RIKON 80-805 is the specialist worth owning alongside it, because 1750 rpm combined with a fixed jig angle protects an edge in a way a 3600 rpm wheel cannot.

For anyone starting out, the WEN BG4276 is a sensible first purchase, and the variable-speed WEN BG625V is the better buy if you think you will grow into it. Replace the factory wheels with finer grits, bolt the machine down, and finish on a stone. That is the whole method, and it is why the best bench grinders for sharpening tools are the ones you can slow down rather than the ones with the biggest motor.
