BTW if it matters, the customer will pay $10k+ for my machines and drill
every 4-5 seconds so this is not a hobby-like application.


Also BTW, the best answer we've had yet is to use inverter rated motors,
slow and stop them on the retract, reverse their rotation at a slow speed
whole a brush probes the flutes and forces the debris down and out of the
drill. Then retract the brush and reverse back up to full RPM... Quite a
"How It's Made" opportunity. grin
