Examples

• 550 RPM to do a 5 mm hole:

Power Tapping - Tapping with a Drill Press

• Requires 2 flute tap to make it easiest, otherwise chips bind up
• Same hole and tap using same fixture with drill press - guarantees alignment
• The tap self-feeds the drill press downwards. This implies that this would not be doable so well with a hand-held drill. Mag drill would work.
