Chipbreaker Profile

The SGM05030 features a Variable pitch chipbreaker geometry specifically engineered for 4FL ball nose endmills. The edge preparation includes a controlled hone radius of 0.01–0.02 mm to balance edge strength and surface finish quality. This profile promotes upward chip curl and efficient evacuation through the flutes, preventing built-up edge (BUE) and ensuring consistent machining performance even in sticky materials.

Operating Guidelines

  • Ensure spindle runout is less than 0.005 mm TIR for optimal tool life and surface finish.
  • Use high-pressure coolant (minimum 70 bar) for effective chip evacuation in deep cavity milling.
  • Maintain coolant concentration between 8–12% for water-soluble coolants; use neat oil for titanium and nickel alloys.
  • Reduce cutting speed by 20% when machining materials harder than 45 HRC.
  • Implement trochoidal tool paths for slotting operations wider than 1.5 × D1 to minimize radial engagement.
  • Inspect tool edge condition after every 30 minutes of cutting time in abrasive materials.
  • Store tools in original packaging away from humidity and corrosive environments.

Toolholder Compatibility

The SGM05030 is compatible with the following high-precision toolholding systems:

  • HSK-A50, BT40 hydraulic chucks, shrink-fit holders
  • ER11, ER16, ER20 precision collets with ≤0.01 mm runout
  • Shrink-fit holders with H4 bore tolerance
  • Hydraulic expansion chucks for vibration-dampened finishing
  • Recommended clamping torque: 8–12 Nm for 4.0 mm shank
