Review on 45 Speed Steel Gauge for Gyros 22010 by Joe Lantz
Drills have a good cutting edge, they are sharp.
I was surprised they didn't bend or break under hand pressure with a hand vise. Drilled 27 holes with a .025 bit in 1/4 thick very hard plastic. I was very surprised when they didn't bend or break when used with a Dremel power tool. Buy the same as the chuck to use these drill bits on my Dremel tool. I drilled 36 holes with a .031 bit in a teflon guide.
Pros
- Very impressive
Cons
- Large and bulky
