Chipbreaker Profile

Advanced flute profile with variable helix angle minimizes vibration and improves surface finish quality. The through-coolant (TD) design delivers coolant directly to the cutting edge at pressures up to 70 bar, ensuring effective temperature management and chip breaking even in blind-hole applications.

Operating Guidelines

  • Always use through-coolant at minimum 20 bar pressure for optimal chip evacuation and tool life
  • For depths exceeding 3×D, employ a peck drilling cycle with 1×D peck depth and 50% retract
  • Maintain runout below 0.01 mm TIR to prevent premature corner wear and ensure hole straightness
  • Verify workpiece clamping rigidity; minimum clamping force should resist 1.5× maximum thrust force
  • When entering inclined surfaces, reduce feed to 50% for the first 0.5×D engagement depth
  • Monitor spindle load; do not exceed 85% of rated spindle torque during drilling operations
  • Replace tool when flank wear exceeds 0.15 mm or when burr formation increases significantly
