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. We recommend using a water-soluble or oil-based lubricant for stones that are not oil filled.

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.

Polishing Stones for EDM Scale Removal
Remove the tough scale left by the EDM (electrical discharge machining) process. These stones are harder than standard aluminum oxide polishing stones but are not so hard that they will scratch or gouge your workpiece. They abrade slowly, so you can control how much material you remove.
Polish by hand or use these stones in power tools with a compatible holder. You’ll also need lubricant.

Polishing Stones for Hard Metals
Remove imperfections on tools, molds, and dies made from high-grade steel, such as P20 and H13 tool steel, 420 stainless steel, and more. These stones are harder than standard aluminum oxide stones. Thanks to their aluminum oxide abrasive, they slowly remove material to give you more control over how much you take off. Polish with them by hand or secure them in a power tool with the compatible holder. To stop debris from building up, apply a water-soluble or oil-based lubricant during use.

Polishing Stones for Soft Metals
Prevent scratches, tears, and gouges in aluminum, brass, and other soft metal molds and dies as you polish. These stones are softer than standard aluminum oxide stones. Thanks to their aluminum oxide abrasive, they slowly remove material to give you more control over how much you take off. Polish by hand or mount them in power tools with a compatible holder. To keep debris from clogging the surface, apply a water-soluble or oil-based lubricant during use.
