A bench grinder spins a pair of abrasive wheels for shaping and sharpening tools such as chisels, plane irons and drill bits. Wheel speed matters: standard 3,450 to 3,600 RPM models remove metal quickly, while low or variable speed models give more control and tend to run cooler at the edge.
The six grinders below are all 8 inch designs, from a low-speed RIKON to two variable-speed models and a grinder with a belt sander. Motor, speed and weight come from each product’s listing page. We have not used these grinders ourselves. Power figures are the makers’ own, and the manual covers wheel mounting, guards and tool rests.

Bench Grinder FAQ
Why does speed matter for sharpening?
Lower speeds give finer control and let the edge stay cooler. Many tool sharpeners prefer slow or variable models.
Do I need a water tray?
It helps cool a tool while you work. It is not a substitute for light passes.
The Short Version
For standard speed with lights, the Metabo. For variable speed with a water tray, the VEVOR MD200GT. For variable speed and work rests, the Shop Fox. For slow speed on a cast base, the RIKON. For a water tray and warranty, the SKIL. For a belt sander too, the VEVOR combo.
