I am drilling a hole in A36. It has been difficult with multiple sharpenings per hole. I don’t mean the final hole, I mean per step I need to sharpen 2-4 times. I am using a Silver and Demming set of bits. Using lathe is not an option due to the length of the piece.
Details
Final diameter 1inch
A36 alloy 1.5 inches thick
Using small manual mill
Turning at minimum speed which is 315 RPM
Two questions
What is the proper way to drill, how many bits to use to finally get to 1 inch?
What is an easy way to get a pilot hole drilled all the way through?
