A bench grinder is a stationary tool that spins abrasive wheels for sharpening, shaping, deburring, and cleaning metal. The best bench grinder for your shop depends on the size of the work, the bench space you have, and the motor and wheel features that match your routine.

How to Choose
Matching a bench grinder to your work starts with the same fields that appear on the listings above: wheel size, motor output, speed, included wheels, guards, and mounting. Use the table below to compare the five picks side by side. For more on sharpening technique, see our chisel sharpening guide.
Wheel Size and Speed
Full-size grinders in this roundup use 8-inch wheels and run at 3,450 to 3,600 rpm. The WEN is a 6-inch model at 3,450 rpm. The Ecarke is a 3-inch mini at variable speed from 2,000 to 10,000 rpm. Larger wheels provide a bigger working surface, while the mini format takes less bench space and can slow down for detailed work.
Motor Power and Capacity
The listings describe motors by horsepower or amperage. The DEWALT and Woodskil are 3/4 hp; the JET is 1 hp; the WEN lists 2.1 amps. For heavier shaping and stock removal, review the amp draw or horsepower on the product page. If the motor data is not clear, check the listing before purchase.
Grinding Wheels and Included Extras
Several models come with two wheels: WEN includes 36- and 60-grit; Woodskil includes 36- and 60-grit alumina; JET includes a 36-grit wheel plus a wire wheel; Ecarke includes 36- and 60-grit mini wheels. The DEWALT listing does not state the included wheel grits. If you need a wire wheel for rust and paint, the JET is the model that includes one. The JET listing also notes it accepts most polishing and buffing wheels.
Stability, Guards, and Tool Rests
DEWALT, JET, and Woodskil list cast iron construction. JET, Woodskil, and Ecarke list rubber feet or anti-vibration feet. WEN and Woodskil list adjustable eye guards; Woodskil also has a spark baffle and CSA certification. Tool rest designs vary: DEWALT lists precision-machined aluminum rests, WEN lists pivoting rests, JET lists cast-iron rests, and Woodskil lists an adjustable angle worktable. A stable base and adjustable guards make bench grinding easier to control.
