I've been happy w/ 13k rpm, 900mm/min and ~8mm per peck. Slow Z and excessive pecking generate too much heat. That $10+ per bit price is insane, metric is typically a lot cheaper if you're patient,...

Solid state relays are a better choice; better isolation/less EMI and a simple two-wire low draw (25ma max, typ <10) trigger (e.g....
What you're showing is tearout and it can happen anytime the bit cuts diagonally across the grain. With plywood circles, each ply has two (opposing) quarters most likely to show tearout. The pictured...
