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
