Chipbreaker Profile
Although the SGM01009 is a solid endmill rather than an indexable insert, its flute geometry incorporates advanced chipbreaker principles:
- Variable Helix Design: Each flute features a slightly different helix angle to suppress chatter and harmonic vibration during high-speed milling.
- Positive Rake Face: The cutting edge presents an optimized positive rake angle that reduces cutting forces, minimizes heat generation, and promotes smooth chip evacuation.
- Core Reinforcement: A robust core diameter of 0.413 mm provides rigidity for deep-pocket milling while maintaining adequate chip flute volume.
- Ball-Nose Profile: The full-radius ball-nose geometry acts as a natural chipbreaker in 3D contouring and finishing passes, directing chips away from the cut zone.
- Edge Preparation: A micro-honed T-land edge preparation (0.02 mm × 20°) prevents chipping on the primary cutting edge while maintaining sharpness for mirror-finish surfaces.

Recommended Cutting Conditions
Values are starting recommendations. Optimize based on machine rigidity, coolant delivery, and workpiece fixturing.
| Material | Vc (m/min) | fz (mm/tooth) | RPM (approx.) | Coolant |
|---|---|---|---|---|
| Mild Steel (P1.1) | 120 – 180 | 0.010 – 0.025 | 60,152 – 90,229 | Emulsion / Air |
| Alloy Steel (P2.5) | 80 – 140 | 0.008 – 0.020 | 40,101 – 70,178 | Emulsion |
| Stainless 304 (M1.0) | 60 – 100 | 0.008 – 0.018 | 30,076 – 50,127 | Emulsion (high pressure) |
| Aluminum 6061 (N1.1) | 300 – 500 | 0.020 – 0.050 | 150,382 – 250,637 | Air / MQL |
| Titanium Ti-6Al-4V (S1.0) | 30 – 60 | 0.005 – 0.012 | 15,038 – 30,076 | Emulsion (flood) |

Operating Guidelines
- Runout Control: Maintain total indicated runout (TIR) below 0.010 mm at the tool tip. Excessive runout will cause uneven flute wear and premature failure.
- Coolant Strategy: For steel and stainless steel, use high-quality water-soluble emulsion at 8-10% concentration. For aluminum, air blast or MQL is preferred to prevent built-up edge.
- Entry Strategy: Use helical or ramp entry when possible. Avoid direct 90° plunging into solid material. If plunging is necessary, reduce feed to 30% and use peck cycles.
- Stepover Recommendation: For finishing, use 5-10% of tool diameter stepover to achieve mirror surface finish (Ra 0.2 – 0.4 μm). For semi-finishing, 20-30% stepover is acceptable.
- Tool Life Monitoring: Inspect the ball-nose radius after every 30-60 minutes of cutting time. A worn radius will produce visible witness marks on contoured surfaces.
- Storage: Store in original packaging away from moisture and vibration. Do not allow tools to contact each other to prevent edge chipping.
Toolholder Compatibility
| Holder Type | Shank Fit | Clamping Force | Runout Potential | Recommended |

| Shrink Fit | H6 | Very high | ≤0.002 mm | ★★★★★ Best for finishing |
| Collet Chuck (ER16/ER20) | H6 | Medium | 0.005 – 0.015 mm | ★★★★☆ Acceptable |
| Milling Chuck (Power) | H6 | High | 0.003 – 0.008 mm | ★★★★☆ Good for roughing |
| Weldon Side-Lock | H6 | Medium | 0.010 – 0.025 mm | ★★☆☆☆ Not recommended for finishing |
