Have a job that we're running with an 1" indexable drill 1.5" Deep in 6061 without CTS at 3,000 RPM, 12IPM and pecking .250" and the deeper it gets the worst it sounds. The chips look good, no BUE but sounds rough. Without CTS, would a spade drill be a better option?
The holes get profiled to size so I don't care about the finish the drill leaves just need to get a better MRR.
This is on a 40 taper machine if that matters.
