Can I use a metal drill bit for plastic?
Yes but there are challenges with the kind of pressure a standard jobbers drill creates in cut. The problem in the web of the drill creating too high of thrust forces when cutting the plastic. This can result in unwanted fracturing on the sides and bad breakout when its through the hole.
How do I identify a drill bit?
- Wood Drill Bits: These can be identified by a small, pointed tip at the very end. If you look closely, you can see spurs on each side.
- Masonry Drill Bits: These bits have a gently sloping tip.
- Metal Drill Bits: These have a wide-angled point at the end, and they may also be painted black.
What is each drill bit used for?

What are all the different types of drill bits?
- Twist Drill Bits. Also known as high-speed bits, they resemble corkscrews and are some of the most popular bits.
- Brad Point Drill Bits.
- Masonry Drill Bits.
- Rivet Drill Bits.
- Spade Drill Bits.
- Installer Bits.
- Step Bits.
- Auger Bits.
Are drillbits color coded?
