Larry, Thank you for that.
I am a woodworker by trade and I know I will never find brad point bits in the sizes I need.
Specifically:19, 14, and 8 wire size in stub length, jobber, and aircraft length..
It was something about squaring the tip, and removing the margin on the flutes.
I've seen an article...maybe here...on how to alter a conventional bit to drill Delrin.
Please point me back to that article; I can't find it. I do ok with cold air on the bit and lots of pecking (manual lathe), but it heats up so damn quick!
Does someone make a bit specifically for drilling...
