9. Recommended Cutting Conditions
Values shown are starting recommendations. Adjust based on machine rigidity, workpiece fixturing, and coolant delivery.
| Workpiece Material | Cutting Speed Vc (m/min) | Feed per Tooth fz (mm) | Depth of Cut ap (mm) | Coolant |
|---|---|---|---|---|
| Carbon Steel (≤ 30 HRC) | 84 - 104 | 0.0008 - 0.0001 | ≤ 0.013 | Emulsion / Air |
| Alloy Steel (30-45 HRC) | 64 - 84 | 0.0008 - 0.0001 | ≤ 0.011 | Emulsion / MQL |
| Hardened Steel (45-55 HRC) | 44 - 64 | 0.0005 - 0.0001 | ≤ 0.007 | Air / MQL |

10. Operating Guidelines
- Run-in Procedure: Reduce cutting speed by 20% for the first 5 minutes of operation to allow coating adaptation
- Tool Overhang: Keep tool overhang (L/D ratio) ≤ 4:1 for optimal stability; use shrink-fit holders for L/D > 5:1
- Chip Evacuation: Ensure adequate coolant pressure (≥ 70 bar for high-speed applications) to prevent chip recutting
- Entry Strategy: Use ramp entry at 1-2° angle or pre-drill entry hole to avoid full-width engagement shock
- Speed/Feed Adjustment: If chatter occurs, reduce speed by 10% and increase feed by 15%; if edge wear is excessive, reduce feed by 20%
- Tool Life Monitoring: Inspect tool after every 30 minutes of cutting time; expected tool life: 45-90 minutes under recommended conditions
- Storage: Store in original packaging at 15-25°C with <60% humidity; avoid contact with other tools to prevent edge damage
11. Toolholder Compatibility
For optimal performance with the 0.011" diameter SGM02318, the following holder types are recommended:
| Holder Type | TIR (max) | Best Application | Clamping Torque |
|---|---|---|---|
| Weldon Flat | ≤ 0.010 mm | Heavy roughing, high torque | 12-18 Nm (set screw) |
| Shrink Fit H6 | ≤ 0.003 mm | High-speed finishing, micro-machining | N/A (thermal interference) |
| Hydraulic H6 | ≤ 0.005 mm | Universal milling, good damping | N/A (hydraulic clamping) |
Holder Selection Tip: For this 0.011" tool, prioritize holders with TIR ≤ 0.005 mm. Shrink-fit or hydraulic holders are strongly recommended for speeds above 15,000 RPM or when surface finish requirements exceed Ra 0.4 μm.
