Operating Guidelines

  • Coolant: High-pressure internal coolant (20+ bar) strongly recommended for holes deeper than 2×D
  • Peck Cycle: For blind holes >3×D, use peck depth of 1×D with full retract to break chips
  • Entry Angle: Drill can self-center up to 15° inclined surfaces; reduce feed to 50% for first 1×D
  • Speed/Feed Ramp: Ramp up to full parameters over the first 10 holes to condition the cutting edge
  • Tool Life Check: Monitor flank wear (VB max 0.3 mm) and replace before quality degradation
  • Storage: Store in original packaging; avoid contact between cutting edges to prevent chipping
