Bits

Most rotary tool bits are designed for very high speeds and would not work well in a drill. The maximum speeds for each type of bit can be found in the manual, but it would be nice to build a more intuitive overview here as well.

• small twist drill bits
• abrasive cutting discs for metals (like a tiny disc grinder)
  • also work great with stripboard
  • not suitable for aluminum (too soft, clogs up the disc and can cause dangerous overheating)
• sanding drums (ideal for wood)
• wire brushes - never operate above 15000 rpm, these can shoot little wire pieces at you even at lower speeds!
• grinding stones
• polishing pads
• abrasive burrs
• ...and more

There are some generic products on the market which may be of similar quality as the original manufacturers' bits but are much cheaper.

Other Useful Accessories
