Made from tough tungsten carbide, Perma-Grit® Rotary Attachments are designed to cut and shape your composite materials aggressively and with great precision. Use them to cut through fiberglass and carbon fiber laminates with ease.

Each attachment is supplied with a 0.12" (6 mm) arbor and is turned down from steel before the tungsten carbide grit is welded to the surface. This allows for smooth, well-balanced operation with a powered rotary cutting tool, like our hand-held #2307 Dremel. They will not "fray" or shatter the edges of your composite, leaving little to no need for finish work.

Perma-Grit Attachments feature a special grit cutting edge for use with traditional or reverse-drive drills. After repeated use, attachments have proven to maintain their edge without breakage, and cut even more aggressively than more expensive diamond materials. They don't clog easily, but can be cleaned, if necessary, with a wire brush and/or Acetone (part #9).
