Smoothing and Polishing Stones

Maintain tools, molds, and dies. These stones can be used by hand or in power tools with a compatible holder. Choose the shape that best matches the contour of your work surface.

Aluminum–oxide stones abrade slowly to create a consistent surface. Also known as India stones.

Novaculite stones have extremely fine grains that cut very slowly for the most control over finishing. Also known as Arkansas stones. Grit is approximate. We recommend using a water-soluble or oil-based lubricant.

Bench and Pedestal Grinding Wheels for Carbide, Ceramics, and Glass

The perforated honeycomb pattern cuts carbide, ceramics, and glass without the need for cleaning.

Wheels are made of diamond-coated steel molded onto plastic, so they can be used wet or dry. Diamond is extremely hard and wear resistant.

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