Choose bench grinders by wheel size, speed and the work you need to hold safely. A fixed-speed unit can suit compatible deburring or sharpening. Consider a variable- or dual-speed model when the wheel and material call for a different speed.

Check the wheel, arbor and rated speed

Frequently asked questions
Can I fit an 8-inch wheel on a 6-inch bench grinder?
Use only wheels with the dimensions, type and rated speed specified for the machine. The guard and arbor must match the wheel.
What speed should I choose for sharpening?
Use a wheel and speed approved for the material and tool. Control heat as directed and choose a different sharpening method if needed.
How close should the work rest be?
Follow the manual and applicable rules. OSHA’s grinder checklist specifies a maximum 1/8-inch work-rest clearance for covered workplace equipment.
Do the tool’s eye shields replace safety glasses?
