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.

Straight Triangular

Aluminum Oxide Abrasive—Aluminum oxide stones, also known as India stones, scrape away material slowly to give you more control over how much material you take off. They are good for the final stage of polishing.

Oscillating Tool Backup Pads for Sanding


Starlock Mount	Open Mount

Use these pads on an oscillating tool to support a sanding sheet. Hook and loop lets you quickly attach, remove, and reuse the sheets.

Starlock Mount—Starlock-mount pads can be used with any Starlock-compatible oscillating tools. They have holes to allow dust removal when you connect your tool to a dust extractor and vacuum system to prevent buildup of debris on the abrasive surface.

Open Mount—Open-mount pads are compatible with any non-Starlock oscillating tool. Operate your oscillating tool at two-thirds its maximum speed when using one of these pads.

Handheld Sharpening Stones

Grip by hand and sharpen tools at the angle you need.

Straight Triangle Stone—For Straight and Serrated Blade Edges

Novaculite—Novaculite has extremely fine grains that cut very slowly for the most control over sharpening. Also known as Arkansas stones.

Ceramic Alumina—Extremely hard and wear resistant, these stones sharpen your hardest blades. They cut hard materials slower than cubic boron nitride (CBN) and diamond for finer control.

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.

Straight Triangular

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.

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.

Oscillating Tool Sanding Pad Kits


For Triangle Sheet	Starlock Mount

Everything you need to use your oscillating tool as a sander—great for smaller jobs that a large sander can’t accommodate. Swap out sheets on the backup pads quickly thanks to the hook and loop. These can be used with Starlock-compatible oscillating tools.

For Triangle Sheet—Triangle-shaped sheets reach into tight corners and spaces. They have holes to allow dust removal when you connect your tool to a dust extractor and vacuum system to prevent buildup of debris on the abrasive surface.
