How to choose
- Grinding vs. cut-off: 1/4 in. thick grinding wheels are for side grinding; thin cut-off wheels are for cutting only and must not be side-loaded
- Match the grinder: 4-1/2 in. wheels fit most hand grinders; 7 in. wheels need a large grinder rated for that size and RPM
- Arbor: 7/8 in. arbor wheels mount with a flange nut; 5/8-11 hubbed wheels thread straight onto the spindle for faster changes
- Material: pick metal wheels for steel and masonry wheels or diamond cup wheels for concrete and stone
