Rotary tools such as the Dremel, Fordom and Black & Decker systems use high-speed, low-torque motors to power a variety of accessories. Bits, brushes, burrs and other attachments spin at 5,000 to 35,000 rpm to cut, clean, grind or shape nearly any material. Accessories attach either directly to the tool or to a flexible shaft that allows more freedom of movement.

Instructions
1
Select the appropriate attachment for your application. Place it in the collet and tighten the collet nut to secure it.
2
Use a light touch and let the rotary tool do the work. Make several passes with light pressure instead of one heavy-handed pass.
3
Use a wire brush attachment at low speeds (below 15,000 rpm) to remove rust and clean metal objects. Always use a brush made of a material softer than the item you're cleaning to avoid damage.
4
Attach a cutting bit to the rotary tool for clean cuts in drywall or ceramic tile. Use a cutting wheel on a mandrel to cut through metal.
5
Use router bits to make mortises and shape wood and other soft materials. Don't attach router bits to a flexible shaft as they may kick back during operation.
6
Attach a high-speed cutter to carve or shape soft metals, wood or plastic. Use an engraving cutter bit for more intricate work.
7
Attach an aluminum-oxide abrasive wheel to the rotary tool for removing paint or polishing steel. Use felt or synthetic pads on a mandrel for cleaning and final polishing at lower speeds.
