Best Bench Grinders (2026)

The RIKON 80-805 is built for sharpening. A 1/2 HP motor turns two 8 inch wheels at 1,750 RPM, half the speed of a standard grinder, and the listing says this reduces heat build-up. It ships with 60 grit and 120 grit wheels, so you can shape an edge and then refine it, and the tool rests are adjustable.

Heat is the enemy of tool steel. At 3,450 RPM a chisel blue-tints in seconds and loses its temper, while at 1,750 RPM you have more time before the edge overheats. A larger 8 inch wheel also gives a flatter, gentler hollow grind than a 6 inch wheel. Compared with the DEWALT DW758 in this guide, the RIKON gives up raw cutting speed and gains control.

The tradeoff is that slow speed makes heavy stock removal slower, so it is a poor choice for grinding bolts or cleaning weld spatter. Dress the wheels regularly with a diamond dresser, set the tool rest within 1/8 inch of the wheel and wear eye protection. It is the pick for woodworkers. A diamond dresser and a basic angle jig are the two cheap accessories that make this machine far more useful.

The BUCKTOOL 3/4HP is a low-speed grinder with a 4.8 amp induction motor rated 3/4 HP, 1-1/4 HP at peak, spinning two 8 inch wheels at 1,750 RPM. It is designed to take a 1-1/2 inch wide wheel, which gives you more surface for wide tools, and the listing says it is ready for a CBN (cubic boron nitride) wheel.

A CBN wheel is the modern upgrade for sharpening. It cuts cool, never needs dressing and holds its shape for years. The extra motor power helps because CBN wheels are heavier and need steady torque at low speed. Compared with the RIKON 80-805, this unit has more power and a wider wheel, and is aimed at turners and carpenters.

The peak horsepower figure is a marketing number, so treat 3/4 HP as the true rating. Expect to buy a CBN wheel separately, and a jig for repeatable angles. Keep the rests close to the wheel. It suits turners and serious sharpening. If you add a CBN wheel, balance it on the arbor and check the maker's rated RPM against the grinder before mounting.

The DW758 is a classic shop grinder: a 3/4 HP induction motor, 8 inch wheels and a cast iron base and housing, which the listing says gives durability and a long life. Induction motors are quieter and last longer than universal motors, and the cast iron absorbs vibration.

It is a general-purpose grinder for shaping metal, removing rust and rough sharpening of tools like shovels and mower blades. At standard speed it cuts quickly, and that speed is also its limit for delicate sharpening. Compared with the RIKON low-speed unit, it hogs off metal faster but will burn a chisel if you press.

The DEWALT name brings a good dealer and service network. Plan on dressing the wheels, replacing them when they wear down and setting the tool rests properly. It is a sound main grinder for a mixed shop. Keep a bucket of water beside any standard-speed grinder, since cooling the tool every few seconds is the only way to protect its temper.

The JET JBG-8W is the most powerful grinder in the group at 1 HP, with a capacitor-start induction motor driving both 8 inch wheels at 3,450 RPM. One side carries a 36 grit vitrified aluminum oxide wheel for shaping, and the other a wire wheel for cleaning rust and scale. The base and tool rests are cast iron.

The extra horsepower helps it keep speed under load, so it does not bog when you press hard on a bolt or a chisel. Capacitor-start motors give strong starting torque, which matters when you spin up a heavy 8 inch wheel. Compared with the DEWALT DW758 at 3/4 HP, it has more motor and a wire wheel but similar overall use.

Wire wheels throw loose wires, so wear eye and face protection. The 36 grit wheel is coarse for shaping, so you will want a finer wheel for sharpening. It is a workhorse for a general shop. Replace the wire wheel when the wires fray, because a worn one sheds bristles that can embed in skin.

The BUCKTOOL dual-speed grinder gives you both a low and a high speed on one machine, with a 1/2 HP induction motor, cast iron base and two white aluminum oxide wheels in 80 and 120 grit. The listing describes a buffer combo, meaning one end may take a buffing wheel as well.

Dual speed is the feature that makes it flexible. Run low speed for sharpening to keep steel cool and high speed for shaping and rust removal. White aluminum oxide wheels run cooler than gray ones, which suits sharpening, and the 80 and 120 grit pair covers rough and fine work. Compared with the RIKON, it adds a high-speed option for a small increase in complexity.

A 1/2 HP motor is modest, so heavy grinding will bog it. Dress the wheels and check the rests. It is a good all-rounder for a mixed woodworking and light metalwork shop. Switch to low speed before touching a finished edge and high speed only for removing material.

The WEN BG625V is a small 6 inch grinder with a 2.5 amp variable speed motor from 2,000 to 3,400 RPM and a flexible work light. The listing positions it for reviving old tools, knives and bits.

Variable speed in a budget unit is useful. You can drop to 2,000 RPM for sharpening and go up for shaping. The 6 inch wheels are smaller and have less surface speed than 8 inch ones, so the grind is more hollow and less flat. A 2.5 amp motor is a light-duty rating, so heavy grinding stalls it. Compared with the JET and DEWALT units, it is the cheap, light option.

It makes sense for a garage hobbyist who sharpens kitchen knives, garden tools and drill bits. Dress the wheels, set the rests close and use eye protection. It is a modest machine at a modest price. Treat the work light as a bonus and add a stronger bench light if you sharpen often.
