Okay, Smack me, I am a Noob.
I am having an annoying problem drilling blanks. Seems that the bit likes to "Squeal like a stuck pig". I have a new, sharp, brad-point bit (7mm from Penn State) and no matter what type of wood I am drilling, this hideous squeal comes about midway though the blank. It is so loud, I have to use Hearing Protectors and my dogs run and hide. Any suggestions to quiet this? I am running at a fairly low speed, about 900-1000 rpm. I tried a little Empire (top saver) lube on the bit, It helped a little, but not much. Would parafin (candle wax) help? I have tried other speeds on the drill press, but it makes no difference. Runout is minimal, the bit is square to the table. All other alignments are in spec.
Thanks,
Dave
