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
