Lets talk about drill bits Media

Published: 13 years ago

Shows my collection of drill bits and I talk about deep hole drilling in aluminum and the use of parabolic drill bits. Halfway through I show a drill bit that has been loaded up with chips until it stalled in the hole.

This was taken just after my "G0602 Lathe motor standoff" video due to my frustration with not being able to drill the hole I wanted to. In the end I was able to squeak by making my 12 remaining parts using 1200rpm, 4ipm (up from 2ipm before) and more oil added to my coolant (it was getting pretty watery).
