Chipbreaker Profile

The SGM07180 features a precision-ground two-flute geometry with an optimized chipbreaker profile designed for micro-drilling operations. The flute design incorporates a variable helix angle that promotes upward chip flow while minimizing cutting forces and burr formation.

  • Flute Form: Parabolic flute profile for enhanced chip evacuation in deep-hole drilling
  • Chipbreaker Width: 0.075 mm optimized for 0.5 mm diameter
  • Rake Angle: 12° positive rake for reduced cutting resistance
  • Clearance Angle: 8° primary clearance + 15° secondary clearance
  • Margin Width: 0.04 mm for improved hole straightness and surface finish
  • Edge Preparation: 0.01 mm hone (T-land) for edge strength without compromising sharpness

Operating Guidelines

  • Runout Tolerance: Maximum tool runout should not exceed 0.005 mm (TIR) to prevent premature edge chipping and ensure hole accuracy.
  • Peck Drilling: For depths exceeding 2xD, use a peck cycle with retract distance of 0.5-1xD to facilitate chip breaking and evacuation.
  • Coolant Pressure: Minimum 20 bar (290 psi) for through-tool coolant; external flood coolant at 10-15 L/min for standard applications.
  • Spindle Warm-up: Allow 10-15 minutes spindle warm-up at 5,000 RPM before production to ensure thermal stability.
  • Entry Angle: Use a chamfer or center drill (90°) to guide the tool and prevent walk-off on inclined surfaces.
  • Tool Life Monitoring: Monitor flank wear (VB) and replace when VB exceeds 0.05 mm or when burr formation increases significantly.
