I make this part frequently from 416. I thought I would try it using POM-C. My normal work path is to center drill followed by a 9/16" through hole followed by a 1-1/8" hole to a specified depth. The results shown below are not good using the 1-1/8" bit. I was running at 30 rpm and the bit was pulling itself through the material with such aggressiveness that it pulled the 3MT chuck shank from the drill press spindle.
How can I improve this?
