Dremel 3000 Rotary Multi-Tool


The Dremel multitool is a handheld rotary tool that uses a variety of attachments and accessories. You can use a Dremel tool on wood, metal, glass, electronics, plastic, and many other materials. Dremel tools are very useful for fine detailing and finishing.

This versatile tool is based to a rotation bit at high speed which is held in place with a collet. The Dremel concept relies on high speed as opposed to the high torque of a conventional power drill. By inserting an appropriate bit the tool can perform drilling, grinding, sharpening, cutting, cleaning, polishing, sanding, routing, carving, and engraving.


Always wear safety glasses

How to use

  • Make sure to change the bit while the Dremel is turned off and unplugged.
  • Insert or change bit. Place the bit into the hole at the end of the Dremel and back it out slightly. Tighten the collet nut so that the bit is secure and won't wiggle.
  • To remove the bit, press down on the shaft lock button while turning the collet. This should loosen the bit so you can replace it.
  • Turn on. With the lever on the top of the machine choose the rotation speed. Be careful, this is also the turn on command, when you increase the speed, the spindle starts to move

The bits

Use the right bit for the job. You should choose your bit attachment based on the type of material you'll be working with. Dremel makes many bits with a variety of materials for almost any material. For example, for: Carving and engraving jobs: use high speed cutters, engraving cutters, structured tooth carbide cutters, tungsten carbide cutters and diamond wheel points Routing jobs: use router bits (straight, keyhole, corner, or groove). When using a router, take care to only use router bits. Small drilling jobs: use drill bits (purchased individually or as a set)

Grinding, Sanding, and Polishing

Grinding For grinding, attach the grinding stone bit which can be fixed to the mandrel/shaft. Slide the grinding stone into the front of the tool where it is fully inserted and tighten. Turn your Dremel on and grind on a low setting so you don't overheat the material. Gently hold the grinding stone against the material until it wears down.[12]

  • You can use grinding stones, grinding wheels, chain saw sharpening stones, abrasive wheels and abrasive points to grind a material. Carbide bits tend to work best on metal, porcelain, or ceramic.
  • Use cylindrical or triangular tips for round grinds. To grind a notch into something or grind an inside corner, use a flat disc shape. Or, use cylindrical or triangular tips for round grinding.

Sharpening or sanding Select a sandpaper bit and secure it in your Dremel. Sandpaper bits are available in fine through course grits, and all grades should fit on the same mandrel. Tighten the screw at the end of the sandpaper bit. Turn on your Dremel and set it between 2 and 10. Choose lower settings if you're sanding or polishing plastics or woods. Select a higher setting if you're sanding metal. While holding the material secure, run the bit across the material so that the sandpaper bit completely comes into contact with your material and sharpens or sands it.[13]

  • Make sure that the sanding bits are in good shape so they don't scuff or mark your material. They should fit in the drill snugly and shouldn't be worn down. Have several sanding bits on hand so you can quickly replace them.
  • To sand, you can use sanding bands, sanding discs, flap wheels, shaping wheels and finishing and detail abrasive brushes.
