Chipbreaker Profile

The SGM08050 features an optimized 2-flute geometry with a precision-ground chipbreaker designed for stainless steel. The flute profile ensures efficient chip evacuation, reduces cutting forces by up to 15%, and minimizes built-up edge (BUE) formation. The polished flute surface (Ra 0.2 μm) enhances chip flow and prevents material adhesion during high-speed operations.

Operating Guidelines

  • Always use high-pressure coolant (minimum 70 bar) for depths exceeding 3xD to ensure proper chip evacuation and heat dissipation.
  • Maintain rigid toolholder and workpiece clamping. Minimum recommended spindle runout: 0.01 mm at the tool tip.
  • For peck drilling cycles, use a retract value of 0.5-1.0 mm and reduce feed by 20% at each peck entry.
  • Ensure coolant concentration of 8-12% for water-miscible fluids; use neat oil for difficult-to-machine materials.
  • Inspect tool wear after every 50 holes; replace when flank wear exceeds 0.15 mm or when burr formation increases.
  • Store tools in original packaging at 15-25°C with humidity below 60% to prevent corrosion of the precision ground edges.
