Recommended Cutting Conditions
| Material | Cutting Speed Vc (m/min) | Feed fn (mm/rev) | Coolant |
| Carbon Steel (<700 N/mm²) | 30-50 | 0.15-0.25 | Emulsion / MQL |
| Stainless Steel | 15-30 | 0.10-0.18 | Emulsion (high pressure) |
| Aluminum Alloy | 60-100 | 0.20-0.35 | Air blast / MQL |
| Cast Iron (GG/GGG) | 80-120 | 0.15-0.25 | Dry or compressed air |
| Titanium Alloy | 15-25 | 0.05-0.10 | High-pressure emulsion |
Note: Values are starting recommendations. Optimize based on machine rigidity, workpiece clamping, and coolant delivery. Reduce speeds by 15% for depths exceeding 3xD.
Operating Guidelines
- Run-in Period: Reduce feed by 30% for the first 50 holes to condition the cutting edge.
- Coolant Flow: Ensure adequate coolant delivery to the drill point. Minimum 20 bar pressure for deep-hole applications.
- Tool Runout: Maintain maximum 0.01mm TIR at the tool tip for optimal performance and hole accuracy.
- Peck Cycle: For holes deeper than 3xD, implement peck drilling with 1.5D to 2D peck depth.
- Chip Control: Monitor chip formation. Long, unbroken chips indicate insufficient feed; powdery chips indicate excessive wear.
- Re-sharpening: Not recommended. Solid carbide drills are designed as disposable precision tools for maximum consistency.
- Storage: Store in original packaging away from vibration and humidity to prevent edge chipping.
