Drill Bits Bending

[george wilson]

Interesting bending of carbide drills. I only ever use them for drilling out broken taps,so don't have much real experience with them. And then,I only use the straight flute variety,or solid spade pointed ones. I haven't seen small carbide end mills doing any bending without shattering,and I do use them. But must bow to carbide drill experience.

I can see that small carbide drills would bend more than larger ones. I suppose they are thinner in diameter for their length,allowing more bending to take place.

Must be a different manufacturer than the ones I have seen. Most chip or break at the mere sight of the work.

If I had a set of those drills I could retire my right angle drill.
