Chipbreaker Profile

The SGS56131 features a proprietary GH - High-feed chipbreaker for stable machining optimized for alloy steel (≤ 55 hrc) machining. The flute geometry incorporates a variable helix design that reduces harmonic vibration and promotes stable chip formation. Wide, polished flutes ensure rapid chip evacuation, preventing recutting and extending tool life.

FeatureBenefit
Variable Helix AngleReduces chatter and vibration in high-speed drilling
Polished Flute SurfaceMinimizes chip adhesion and built-up edge formation
Reinforced CoreEnhanced torsional rigidity for stable hole accuracy
Self-Centering PointEliminates wandering on inclined or curved entry surfaces

Recommended Applications & Workpiece Materials

High-speed machining of steel and cast iron. Optimized for production environments requiring maximum metal removal rates.

Spindle Speed (n)25873881RPM
Depth of Cut (ap)12.312.3mm (full diameter)
Max Hole Depth-30.8mm (3xD standard)

Note: Start at the lower end of the parameter range and increase gradually based on machine stability and chip formation. Use internal coolant (10-15% emulsion or MQL) for optimal performance.

Operating Guidelines

  • Ensure workpiece clamping rigidity to prevent vibration and hole oversize.
  • Use through-spindle coolant at minimum 20 bar pressure for holes deeper than 2xD.
  • Peck drilling recommended for depths exceeding 3x cutting diameter.
  • Maintain toolholder TIR below 0.01 mm for holes requiring H7 tolerance.
  • Replace drill when flank wear exceeds 0.15 mm to maintain surface finish.
  • Pre-drill pilot hole (1xD depth, 0.2 mm larger point diameter) for inclined entries >5°.

Toolholder Compatibility

High-precision hydraulic chucks, shrink-fit holders, and milling chucks with TIR ≤ 0.005 mm recommended
