Chipbreaker Profile

The proprietary flute geometry on the #29 PR1725 SGS54701 is designed to produce short, manageable chips even at high feed rates. The optimized land width and rake angle combination ensures:

  • Reduced cutting pressure on the drill point
  • Improved chip flow through the 3-flute gullet
  • Minimized built-up edge (BUE) on stainless and sticky materials
  • Consistent chip formation across the recommended speed/feed window

Operating Guidelines

  • Run-out: Ensure spindle run-out is less than 0.01 mm at the tool tip to prevent uneven wear.
  • Coolant Pressure: Maintain minimum 70 bar (1,000 psi) for through-tool coolant to guarantee adequate chip evacuation in 3×D applications. Through-tool internal coolant (TB) for optimal chip evacuation.
  • Peck Cycle: For blind holes deeper than 2×D, use a peck depth of 1–1.5×D with full retract to break chips.
  • Toolholder: Use hydraulic or shrink-fit holders; collet holders are not recommended for 3×D drills.
  • Entry Surface: Chamfer or spot-drill inclined surfaces to prevent drill walk and corner chipping.
  • Re-sharpening: Not recommended; these solid carbide drills are designed as disposable tools for maximum consistency.
