8. Application Map by Operation
| Operation | Suitability | Notes |
|---|---|---|
| Through-hole Drilling | ✓ Excellent | Optimal chip evacuation |
| Blind-hole Drilling | ✓ Good | Use peck cycle for depths >3D |
| Step Drilling | ✓ Good | Reduce feed by 20% at step |
| Counterboring | △ Fair | Not recommended without pilot |
| Reaming | ✗ Not suitable | Use dedicated reaming inserts |
9. Recommended Cutting Conditions
| Material | Vc (m/min) | fn (mm/rev) | Max Depth |
|---|---|---|---|
| Steel (P.1-P.3) | 120-180 | 0.15-0.30 | 4D |
| Steel (P.4-P.6) | 100-150 | 0.12-0.25 | 3D |
| Stainless (M.1-M.2) | 80-120 | 0.10-0.20 | 3D |
| Cast Iron (K.1-K.3) | 100-140 | 0.20-0.35 | 4D |
| Tool Steel (P.6-P.7) | 60-90 | 0.08-0.15 | 2D |
Conditions are starting recommendations. Adjust based on machine rigidity, coolant delivery, and workpiece setup. Use internal coolant (20-30 bar) for optimal performance.
10. Operating Guidelines
- Coolant: High-pressure internal coolant (minimum 15 bar) is mandatory for depths exceeding 2×D
- Peck Cycle: Implement full retract pecking at 1.5×D intervals for blind holes deeper than 3×D
- Entry Angle: Ensure perpendicular entry (±1°) to prevent corner chipping
- Pre-drill: Use a center drill or spotting drill (120°-140°) for irregular surfaces
- Speed Ramp: Reduce cutting speed by 20% for the first 10 mm to stabilize entry
- Insert Change: Replace insert when flank wear exceeds 0.3 mm or when surface finish degrades
- Tool Life: Typical tool life ranges 15-25 minutes in continuous steel machining at recommended parameters
