Most common drill bit sizes

Recommended Posts

True about drilling metal when I was making my latest Knife I started with a new drillbit and after drilling three holes I had sharpened the drillbit so many times that it was almost down to the shank.

I'm building a clipper at 1/8 scale and do other work at HO scale. I've litterally gone through hundreds of #80 bits in the last 4 years. Next most used would be #78, and #75. Definately buy the more expensive USA made bits. Worth every penny. They don't dull out or break as easily, I can drill over 100 holes with one #80 bit.
