Centerless Grinding Wheels

Remove material and shape metal cylindrical forms or parts without the need for centers or fixtures. These wheels have tight dimensional tolerances and create a smooth surface. They’re good for grinding numerous materials with just a few machines.

Caution: Use only accessories that have a greater rpm rating than the maximum speed of the grinder you choose.
