Best bench grinder
A 3/4 HP 8" grinder with a cast-iron base and machined aluminum tool rests.
A bench grinder is the fastest way to reshape a chipped chisel, put a new bevel on a plane iron or lathe gouge, clean rust off old tools and dress a mower blade. The best bench grinder for most shops is the DEWALT DW758: a 3/4 HP, 8″ grinder with a cast-iron base and machined aluminum tool rests. The RIKON 80-805 is the best bench grinder for woodworking tools, because it runs at 1,750 RPM with white wheels that sharpen cooler, the WEN BG4286 is the budget slow-speed pick and the WEN BG4276 is the cheapest grinder worth buying.
Below are seven picks, from a 6″ budget grinder to a grinder and belt sander combo, a comparison table, short reviews from the makers’ specifications, a buying guide and the setup that makes sharpening repeatable.

Best Bench Grinder Overall
The DW758 is the bench grinder most shops can buy once and keep. A 3/4 HP induction motor spins two 8″ wheels at 3,600 RPM for fast stock removal, and the cast-iron base and motor housing add the weight that keeps a grinder from shaking. DEWALT fits precision-machined aluminum tool rests instead of the stamped steel rests on cheaper grinders, so your chisel or lathe tool sits on a flat, square surface. There’s 12-1/2″ between the wheels, more room than usual for long work, and rear exhaust ports in the guards. It comes with a 36-grit and a 60-grit wheel, eye shields and spark deflectors, and carries DEWALT’s 3-year limited warranty. For fine sharpening, most woodworkers swap one stock wheel for a finer white or CBN wheel. Mid price tier.

Best Bench Grinder for Woodworking
Woodworkers grind for a different reason than mechanics: to put an edge on chisels, plane irons and turning gouges without burning the steel. That’s what the 80-805 is set up for. Its 1/2 HP motor turns at 1,750 RPM, half the speed of a standard grinder, so the edge heats more slowly. It comes with 8″ x 1″ white aluminum oxide wheels in 60 and 120 grit, the friable wheels sharpening jigs are made for, on a 5/8″ arbor. Both tool rests adjust, and the left one has a groove for drill bits. The cast-iron base sits on anti-vibration rubber feet, and RIKON includes adjustable eye shields, spark arrestors and a diamond wheel dresser. It’s backed by a 5-year warranty. Mid price tier.

Best Budget Slow-Speed Grinder
The BG4286 brings the slow-speed idea to the budget price tier. A 3 A soft-start motor turns 8″ x 1″ wheels at up to 1,750 RPM, so edges heat more slowly than on a standard grinder, and the soft start avoids the jolt when you switch on. It comes with a 60-grit general wheel and a 120-grit fine wheel, the same pairing as the RIKON, plus pivoting tool rests, adjustable eye guards and a base with pre-drilled mounting holes. Guards come off easily for wheel changes, which matters if you plan to fit a CBN or white wheel later. WEN backs it for two years. Against the RIKON you give up the diamond dresser, the drill-bit groove and three years of warranty. Budget price tier.

Best Budget 8-Inch Bench Grinder
The BG4282 is an 8″ grinder at a budget price with two features that make sharpening easier. The adjustable eye guards have LED lights built in, so the wheel and the edge are lit where you’re looking, and an on-board quenching tray holds water to cool the work during long sessions, which is what keeps a chisel from losing its temper. A 4.8 A motor turns 8″ x 1″ wheels at up to 3,450 RPM, and WEN includes a 36-grit and a 60-grit wheel and pivoting tool rests. It’s a full-speed grinder, so dip often and use a light touch on thin edges. WEN backs it for two years. Budget price tier.

Best Cheap Bench Grinder
The BG4276 is the lowest price tier here and the simplest way to put a grinder on the bench. A 2.1 A motor turns 6″ x 3/4″ wheels at 3,450 RPM on a 1/2″ arbor, with a 60-grit wheel for general work and a 36-grit wheel for fast removal. A flexible work light points where you need it, the eye guards adjust, and at about 16 lb it’s easy to move or store. For cleaning up rusty tools, reshaping a screwdriver, dressing a mower blade or roughing a bevel, it does the job. For fine sharpening, the small wheels and high speed mean you need a light touch and frequent dips in water. WEN backs it for two years.

Best Variable-Speed Bench Grinder
A variable-speed grinder lets one machine do both jobs: fast grinding at the top of the range and gentler sharpening at the bottom. The BG625V does it on a budget. Its 2.5 A motor runs from 2,000 to 3,400 RPM, set with a dial. It takes 6″ x 3/4″ wheels on a 1/2″ arbor and comes with an 80-grit wheel for general sharpening and a 36-grit wheel for heavy removal. The tool rests pivot for angled work, a flexible work light lights the wheel, and the eye guards adjust. Note that 2,000 RPM on a 6″ wheel is still faster at the rim than a 1,750 RPM 8″ grinder, so quench thin edges. WEN backs it for two years. Budget-to-mid price tier.

Best Bench Grinder and Belt Sander Combo
If you want a bench grinder with a sanding belt, a combo machine puts both on one motor. This one pairs a 6″ grinding wheel at 3,450 RPM with a 2″ x 42″ belt running at 4,480 feet per minute, driven by a 1/3 HP, 3.5 A induction motor. The belt tilts from 0 to 90° and the housing swivels from horizontal to vertical, so you can sand long pieces flat or work on the end of the belt. There are two work tables: a cast-iron one at the belt for sharpening and a larger cast-aluminum one for wood. Belt changes use a quick-release tension and tracking mechanism, and you get a 60-grit white wheel, an adjustable eye shield, an LED light and a cast-iron base on rubber feet. The specs come from BUCKTOOL’s listing. Mid price tier.
How I Chose These Bench Grinders
I started from why woodworkers and DIYers buy a grinder: sharpening edge tools, reshaping damaged ones and general metal cleanup. Then I looked at the bench grinders sold on Amazon today from established brands and picked one for each job: an all-round 8″, a slow-speed grinder for edge tools and a budget version of it, a budget 8″, the cheapest 6″, a variable-speed grinder and a grinder with a sanding belt. Within each group I favored the models more buyers have owned for longer. I compared wheel size, speed, motor, included wheels, warranty and tool rests from the makers’ specifications. I don’t show customer ratings or prices. For how I pick products across the site, see how I choose.
Best Bench Grinder for Woodworking
For woodworking, a grinder’s real job is sharpening, and that changes what to look for. The enemy is heat: if a chisel or plane iron turns blue at the edge, the steel has lost its hardness there and won’t hold an edge until you grind past it. That’s why woodworkers favor slow-speed grinders (1,750 RPM, like the RIKON 80-805 and WEN BG4286) with white aluminum oxide wheels, which break down to expose fresh, sharp grit instead of glazing and heating the steel.
Wheels: Gray, White or CBN
The gray wheels most grinders ship with are hard and coarse, good for steel cleanup and fast shaping. White aluminum oxide wheels cut cooler and are the classic choice for edge tools. CBN (cubic boron nitride) wheels are steel discs coated with abrasive: they don’t wear out of shape or need dressing, run cool and suit high-speed steel turning tools well, but they cost more and need a grinder with a matching arbor, such as the JET JWBG-8NW, which ships without wheels for that reason.
Sharpening Jigs
Freehand grinding takes practice. A jig holds the tool at a fixed angle against the wheel so every grind matches the last, which is how turners keep gouge profiles consistent. Jig systems such as the Pro Grind sharpening system for 8″ grinders mount in front of the wheel; check that your grinder’s wheel height and footprint fit the jig’s base before you buy.
Turners Need a Grinder First
Lathe tools dull within minutes of turning, so for turners a grinder isn’t optional. If you’re setting up for turning, my best wood lathe guide covers the lathe side, and a slow-speed 8″ grinder with a jig is the usual partner.
How to Choose a Bench Grinder
6-Inch or 8-Inch?
An 8″ wheel has a larger radius, so the hollow it grinds into a bevel is shallower, and it has more rim speed at the same RPM, which means faster cutting. 8″ grinders also tend to have bigger motors and tool rests. A 6″ grinder is cheaper, lighter and fine for occasional work. If you’ll sharpen chisels and plane irons or use a jig, buy an 8″.
Speed
Standard grinders run at about 3,450 to 3,600 RPM for fast metal removal. Slow-speed grinders run at about 1,750 RPM, which heats edges less and is the usual choice for woodworking tools. Variable-speed grinders like the WEN BG625V let you choose, though their lowest setting may still be faster than a dedicated slow-speed machine.
Motor and Mass
Induction motors (all the picks here) run quietly and last. A heavier grinder with a cast-iron base, like the DEWALT DW758 or RIKON 80-805, vibrates less, and vibration shows up as a rough, chattered bevel. Bolt any grinder to a bench or a stand; WEN’s 4288T grinder stand puts the wheel at working height and adds a water pot for quenching.
Tool Rests, Lights and Guards
Flat, adjustable tool rests matter more than any other feature for sharpening, because they set the bevel angle. Machined rests are better than stamped steel. Built-in lights help you see the spark line at the edge, and a quench tray or water pot keeps steel cool. Keep the eye shields on and the spark deflectors close to the wheel.
💡 Pro Tip: Dress the Wheel, Dip the Steel
A wheel that’s loaded or out of round grinds hot and uneven. Dress it flat with a diamond dresser before sharpening, keep a cup of water next to the grinder and dip the tool every few seconds, and use light pressure. Stand to one side when you switch a grinder on, in case a wheel is cracked: ring-test new wheels before you mount them.
Bench Grinder With a Sanding Belt
A sanding belt is better than a wheel for flat bevels, knives and shaping wood or plastic. There are two ways to get one. A combo machine like the BUCKTOOL 2×42 puts a wheel and a belt on one motor. Or you can add a belt arm to an 8″ grinder you already own; my guide to choosing a belt grinder compares those attachments with full 2×72 machines. For woodworking rather than metal, a belt and disc sander with a wider belt and a miter gauge is usually the better buy.
🏆 The Verdict
The best bench grinder for most shops is the DEWALT DW758: 3/4 HP, 8″ wheels, a cast-iron base and machined rests. For sharpening chisels, plane irons and lathe tools, the RIKON 80-805 runs at 1,750 RPM with white wheels, and the WEN BG4286 does the same on a budget. The WEN BG4282 is the budget 8″ with lights and a quench tray, the WEN BG4276 the cheapest, the WEN BG625V the variable-speed option, and the BUCKTOOL 2×42 Combo adds a sanding belt.
