In Reply to: Optimum speed for drilling pc boards??? posted by grhughes on May 27, 2012 at 08:30:13:
I thought from the memory of my visits to PCB manufacturing plants that high speed drilling was the norm so I checked.
This from Wiki - "Coated tungsten carbide is recommended since many board materials are very abrasive and drilling must be high RPM and high feed to be cost effective. Drill bits must also remain sharp so as not to mar or tear the traces. Drilling with high-speed-steel is simply not feasible since the drill bits will dull quickly and thus tear the copper and ruin the boards."
