Polishing Stones for Steel

Just the right hardness level for polishing steel tools, molds, and dies. These stones also double as a good choice for general polishing. Choose the stone shape that best matches the contour of your work surface. These stones can be used by hand or in a power tool with a holder (both sold separately). To keep debris from building up, apply a water-soluble or oil-based lubricant during use.

Silicon Carbide Abrasive—Silicon carbide stones, also known as Crystolon stones, are extremely sharp. These stones remove material more quickly than aluminum oxide stones. They are best for the early polishing stage when you want to clear away more material from your work surface. However, they give you less control over material removal than aluminum oxide stones, so stopping at an exact point is more difficult to do.

Clog-Resistant Polishing Stones for Steel

No need to stop and clean these stones as you polish—they’re filled with oil to keep debris from getting stuck in the pores. Use a holder to polish by hand or with a power tool (both sold separately). You’ll also need a water-soluble or oil-based lubricant to wash away debris and reduce friction and heat on your workpiece.

Polishing Stone Assortments for Steel

Keep stones of different grits on hand for each step of polishing steel tools, molds, and dies. The polishing stones in these assortments are the most common choice for general polishing. These stones can be used by hand or in a power tool with a holder (both sold separately). To keep debris from building up, apply a water-soluble or oil-based lubricant during use.

Uniform-Finish Polishing Stones

Prevent uneven polishing marks. Unlike other polishing stones, these stones never leave your work surface for a uniform finish. You move them around with a lapping rod (sold separately), which you can lift off to pause your work—instead of removing the stone. Choose the stone shape that best matches the contour of your work surface.

Lubricate your work surface with either a water-soluble or oil-based lubricant. To make sure the lapping rod doesn’t slip off of the polishing stone as you work, create a small indentation in the stone with a diamond grinding bit. For best results, install the lapping rod in a reciprocating polisher.

Water-Activated Sharpening Stones

Sharpen cutting edges faster and with less pressure than standard stones. Instead of applying a lubricant, add a few splashes of water to form an abrasive slurry. The slurry removes imperfections efficiently, exposing fresh grit as it forms.

For duller blades, sharpen with multiple stones, moving from coarser to finer grits. Use 220 grit to smooth away damage, 500 grit for the initial pass, 1200 grit for polishing, and 1400 grit for an ultra-fine, mirror-like finish.

Add a mat to catch the slurry and keep your work area clean.
