The Dremel is a power rotary tool. The Dremel tool rotates at varying high speeds with different bits to accomplish unique tasks.
The Dremel performs cutting (on glass, plastic, and wood), sharpening, engraving, polishing, & sanding. Put on the specific bit with a wrench for desired bit, for the specific job (some cutting bits are multi-use and can cut multiple surfaces). Make sure the bit is snug before the next job. There are kits which include a variety of bits and other necessities available at your local hard ware store (home depot or lowes) tip: Dremel bit should be nice & snug on the Dremel to avoid slippage.
