Recommended Cutting Conditions
Values are starting recommendations. Optimize based on machine rigidity, workpiece material, and coolant conditions.
| Material | Vc (m/min) | Feed f (mm/rev) | RPM | Coolant |
|---|---|---|---|---|
| Carbon Steel (C45) | 84 | 0.226 | 2822 | Emulsion 8-10% |
| Alloy Steel (42CrMo4) | 74 | 0.206 | 2483 | Emulsion 8-10% |
| Stainless Steel (304) | 61 | 0.177 | 2057 | Emulsion 10-12% |
| Stainless Steel (316) | 53 | 0.162 | 1789 | Emulsion 10-12% |
| Gray Cast Iron (GG25) | 104 | 0.256 | 3493 | Air / MQL |
Operating Guidelines
- Run-in Procedure: Reduce cutting speed by 20% for the first 50 holes to stabilize coating and edge
- Peck Drilling: For holes deeper than 3×D, use peck cycle with 1×D peck depth and full retract
- Coolant Pressure: Minimum 20 bar (290 psi) for through-tool coolant; 10 bar (145 psi) for external
- Coolant Concentration: 8-12% emulsion for steel; 10-15% for stainless steel
- Tool Life Indicator: Monitor flank wear (VB max 0.3 mm) and hole diameter deviation
- Re-sharpening: Not recommended for solid carbide drills; replace when worn
- Storage: Keep in original packaging; avoid contact with other tools to prevent edge chipping
Toolholder Compatibility
| Holder Type | DIN Standard | Clamping Range | Runout |
|---|---|---|---|
| Hydraulic Chuck | DIN 69871 | 9.5 mm | ≤ 3 μm |
| ER Collet (ER16/ER20) | DIN 6499 | 9.5 mm | ≤ 5 μm |
| Shrink Fit Holder | DIN 69893 | 9.5 mm | ≤ 3 μm |
| Drill Chuck (Keyless) | DIN 238 | 0.5-13 mm | ≤ 15 μm |
Recommendation: For optimal hole accuracy and tool life, use hydraulic chucks or shrink-fit holders with runout ≤ 5 μm at 3×D.
