Rotary Tools - Rotary Tool Guidehttp://www.rotary-tools.org/
Rotary tools are handheld power tools that can accomodate rotating bits. They are designed either as a motor with a flexible shaft or as a unit with the rotary bits attached directly to the tool. Many parts and accessories are available to provide drilling, sanding, carving, cutting, grinding, or routing capabilities. These tools use small rasps, trimming tools, and grinding wheels, as well as various bits and burrs.
