Application Map by Operation

Operation TypeSuitabilityNotes
Through-Hole Drilling✓ IdealFull chip evacuation with internal coolant
Blind-Hole Drilling✓ IdealPrecise depth control, reduced burr formation
Peck Drilling✓ RecommendedUse 1.5–2D peck depth for optimal chip breaking
Stack Drilling△ CautionEnsure rigid clamping and alignment
Micro-Drilling✗ Not ApplicableFor diameters < 2.0 mm, use D88-Micro series
Trepanning✗ Not RecommendedUse dedicated trepanning tools

Note: Values are starting recommendations. Optimize based on machine rigidity, coolant delivery, and hole depth. Use internal coolant pressure ≥ 20 bar for optimal performance.

Operating Guidelines

  • Coolant: Use water-soluble coolant (8–10% concentration) or neat oil. Minimum internal coolant pressure: 20 bar (290 psi).
  • Run-In: For first 10 holes, reduce Vc by 20% and fn by 15% to stabilize cutting edge.
  • Peck Cycle: Recommended peck depth = 1.5–2.0 × D for depths > 3×D. Retract fully to clear chips.
  • Entry Angle: Ensure perpendicular entry (±0.5°) or use spot drill (120°) to prevent walk-off.
  • Exit Strategy: Reduce feed by 30% when breaking through to minimize burr formation.
  • Tool Life Check: Monitor flank wear (VB). Resharpen or replace when VB > 0.3 mm or when surface finish degrades.
  • Storage: Store in original packaging at 15–25°C, humidity < 60%. Avoid contact with corrosive agents.
