About Finishing

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.

Fast-Cutting Smoothing Stones

Also known as Crystolon stones, these abrade quickly to create a smooth or extra-smooth finish on 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. We recommend using a water-soluble or oil-based lubricant with stones that are not oil filled.
