I'm predrilling holes in 1/2" ACX plywood (pine) with a 1/8" bit. The bit is a standard straight 2 flute bit and I can't imagine at 12,000 RPM that the wood offers any serious resistance. I'm running an HSD spindle and currently run at 1 ips for one plunge.
From the experience gallery would I have a problem running at 2 ips, or 3 ips for the Z plunge? Should I peck drill? I only ask because I spend a fair amount of time predrilling. I don't want to damage the spindle, but I'd like to run as fast as possible.
I know an air drill and second Z would be best for my projects... I'm saving up for that.
