    Thin-Face Diamond File Sets

    Thinner than standard diamond files, these are good for reaching into small slots and narrow spaces. Diamond is the hardest, longest-lasting abrasive available and strong enough to file hard materials.

    Image of Specification. Front orientation. Files. Diamond File Sets for Ultrasonic Polishers.

    Keep diamond files of different grits and sizes on hand to gradually shape the slots and grooves on your workpiece. Their small size coupled with the rapid vibrations of your ultrasonic polisher give you precise control over where and how much material you remove. Compared to polishing stones, they'll remove more material. The diamond abrasive makes these some of our toughest files. They last through heavy use, even on hard materials. Install them with their holder (sold separately) into the handpiece of an ultrasonic polisher.

    Ultrasonic Stone Holders

    Detail Polishing Stone Assortments

    Keep stones in different grits on hand to smooth ribs, slots, teeth, and other fine features. The stones in these assortments are thin enough to slip into hard-to-reach areas. Made of bonded ceramic, they’re harder and more wear resistant than aluminum oxide stones, but flexible enough not to crack under pressure. Pair these stones with a holder to polish by hand or with a power tool, such as an ultrasonic polisher. Some holders are sold separately. Apply a water-soluble or oil-based lubricant to help keep debris from building up on the surface.

    Ceramic/Diamond Blend Abrasive—Ceramic/diamond stones have diamond particles spread throughout the ceramic to make them harder and sharper. They won’t wear out as quickly as plain ceramic stones when finishing hardened steel, carbide, and other extremely hard materials.
