Recommended Cutting Conditions
| Material | Cutting Speed Vc (m/min) | Feed per Tooth fz (mm) | RPM Range |
|---|---|---|---|
| Carbon Steel (C < 0.5%) | 115–158 | 0.06–0.14 | 7,321–10,058 |
| Alloy Steel (HB 180–280) | 97–134 | 0.06–0.14 | 6,222–8,549 |

| Tool Steel (H13, 40 HRC) | 57–79 | 0.04–0.08 | 3,660–5,029 |
| Titanium Alloy (Ti6Al4V) | 40–55 | 0.02–0.06 | 2,562–3,520 |
Operating Guidelines
- Ramp Entry: Use helical or ramp entry at maximum 2°–3° angle to minimize impact loading on cutting edges.
- Coolant: External flood coolant at 5–8% concentration. Air blast acceptable for dry machining of hardened steels.
- Runout: Maintain TIR below 0.01 mm at the tool tip for optimal tool life and surface finish.
- Chip Load: Start at the lower end of the recommended feed range and increase gradually based on machine stability and chip formation.
- Tool Overhang: Minimize overhang to 3×D or less. For overhangs exceeding 5×D, reduce cutting parameters by 30–40%.
- Edge Preparation: Inspect cutting edges before each use. Do not use tools with chipped or worn edges.
- Storage: Store in original packaging away from moisture and corrosive environments.
