Chipbreaker Profile

The KDZ series features an optimized chipbreaker geometry specifically tuned for 11.3 mm diameter drilling. The land width and groove depth are calibrated to produce tightly curled chips that evacuate smoothly through the flutes, reducing heat buildup and preventing chip jamming in deep-hole applications.

  • Land Width: 0.15 mm (primary), 0.08 mm (secondary)
  • Groove Depth: 0.12 mm
  • Rake Angle: 8° positive
  • Chip Curl Radius: 2.5–4.0 mm (target)
  • Chipbreaker Type: Double-land with central groove

Recommended Cutting Conditions

Values below are starting recommendations for stable setups with internal coolant supply (minimum 20 bar). Adjust based on machine rigidity and workpiece clamping.

Operating Guidelines

  • Coolant: High-pressure internal coolant (20–70 bar) is strongly recommended for 3.0xD drilling to ensure effective chip evacuation and heat dissipation.
  • Peck Cycle: For blind holes exceeding 2.5×D, implement a peck cycle with retract to 0.5×D after each peck depth of 1.0×D.
  • Entry Angle: Ensure the drill enters perpendicular to the surface (±0.5°). Use a spot drill for inclined entries >5°.
  • Pre-drilling: For cast iron or scale-covered surfaces, pre-drill with a 90° spot drill to 0.2×D depth to protect the main cutting edges.
  • Speed Ramp: Reduce cutting speed by 15% for the first 10 mm of engagement to minimize thermal shock on entry.
  • Tool Life Check: Monitor flank wear (VB). Re-index or replace when VB reaches 0.3 mm for steel or 0.4 mm for cast iron.
