Rotary tool bits & attachments

Every rotary tool bit, sorted by job.

76 kinds of bits, wheels, burrs, brushes and attachments for Dremel-style rotary tools — what each one does in plain English, what material it's for, and how they fit wood carving, metalworking and glass etching.

Three artisan kits built from the bits below.

Wood carving

Wood carving kit, step by step

  1. Rough out with a structured-tooth carbide bit (9933/9934) or a carbide shaping wheel (801).
  2. Shape with high-speed steel cutters (114, 115, 117).
  3. Detail with engraving cutters (105–108) — a flex shaft (225) or detailer's grip (A577) steadies your hand.
  4. Smooth with sanding drums (1/4" and 1/2"), then flap wheels and detail abrasive brushes.

Metalworking

Metalworking kit, step by step

  1. Cut with reinforced cut-off wheels (EZ456, thin EZ409) behind a shield (A550).
  2. Deburr and clean welds with orange/brown aluminum oxide stones.
  3. Shape steel with tungsten carbide cutters (9901–9911).
  4. Clean with the right brush — stainless for stainless/aluminum, brass for gold, copper and brass — then polish with felt + 421 compound and rubber points.

Glass etching & engraving

Glass etching & engraving kit, step by step

  1. Etch with diamond wheel points (7103, 7134, 7144) or a diamond burr set — let the diamond do the work with a light touch.
  2. Shape and smooth glass edges with blue/green silicon carbide stones, then the 425 emery wheel.
  3. Drill holes with diamond-tipped glass bits (662DR/663DR, lubricant included).
  4. Steady hands: detailer's grip (A577), a flex shaft, and fine speed control (the Ryobi PBLRT01 dial goes down to 1,000 RPM). Wear eye protection and a dust mask — don't breathe glass dust.

Read this first

  • Shank size: Dremel says all its rotary accessories use a 1/8" shank, except the 461–463 rubber polishing points (3/32"). Milwaukee's M12 rotary tool and Ryobi's rotary tools also come with a 1/8" collet. source ↗
  • Match the abrasive color to the material: orange/brown aluminum oxide for steel and iron; blue/green silicon carbide for stone, glass, ceramics and non-ferrous metals (Dremel catalog).
  • Cut-off wheels cut with the edge only. Don't sand or cut curves with the flat face.
  • Safety: glasses every time, a dust mask for sanding, grinding and glass, and clamp small parts. Fully seat mandrels in the collet. source ↗
