    Match grit size and micron ratings to the texture, appearance, and flatness you need to achieve.

    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.
