I need to machine some HDPE to hold a bunch of specialized tooling for automation cell at work. I need a 1.5D x 1.1 DP hole about 36 times. I bought a 1 1/2" and 1 3/8" spade drill like the one you would use a hand drill to drill through pine.
My two thoughts were that the 1.5" one might do the job or the 1 3/8" one would make me a nasty hole I'd hit with an offset boring head to finish. The work will be done on a Bridgeport.
Thoughts, tips, tricks, warnings welcome.
