Chipbreaker Profile
The SGS51004 incorporates a Narrow-flute high-rake geometry with micro-polished edge for fine chip control. The flute geometry is specifically optimized for the 5.31 mm diameter range, providing:
- Controlled chip curling with reduced cutting pressure
- Enhanced chip evacuation in blind-hole and through-hole operations
- Minimized built-up edge (BUE) formation on ductile materials
- Stable cutting dynamics across variable engagement depths

Application Map by Operation
| Operation | Suitability | Max Depth | Notes |
|---|---|---|---|
| Through-hole Drilling | ★★★★★ | 5×D | Optimal chip evacuation |
| Blind-hole Drilling | ★★★★☆ | 3×D | Use peck cycle recommended |
| Counterboring | ★★★☆☆ | 1×D | Reduce feed by 30% |
| Spot Drilling | ★★★★☆ | 0.5×D | Use rigid setup |
| Micro-hole Drilling | ★★★★★ | 10×D | High-pressure coolant essential |
Recommended Cutting Conditions
| Material | Cutting Speed Vc (m/min) | Feed fn (mm/rev) | Coolant |
|---|---|---|---|
| Carbon Steel | 80-120 | 0.159-0.266 | Emulsion / MQL |
| Alloy Steel | 72-108 | 0.133-0.239 | Emulsion / Oil |
| Stainless Steel | 60-80 | 0.106-0.212 | High-pressure emulsion |
| Cast Iron | 100-140 | 0.212-0.319 | Dry / Compressed air |
| Titanium Alloy | 30-50 | 0.08-0.133 | High-pressure oil |
Note: Values are starting recommendations. Optimize based on machine rigidity, workpiece clamping, and coolant delivery.
Operating Guidelines
- Run-in Period: For the first 5 holes, reduce cutting speed by 20% and feed by 10% to allow coating adaptation.
- Peck Drilling: For depths exceeding 3×D, use a peck cycle with 1×D depth increments and full retract every 2×D.
- Coolant Pressure: Maintain minimum 70 bar (1,000 PSI) for holes deeper than 5×D to ensure adequate chip flushing.
- Tool Life Monitoring: Inspect flank wear every 50 holes. Maximum allowable flank wear (VBmax) = 0.2 mm.
- Storage: Store in original packaging at 15-25°C with <60% humidity. Avoid contact with corrosive agents.
Toolholder Compatibility
Recommended Holder Systems: Precision collet chucks (ER11/ER16), Mini-shrinks (HSK-E25/E32), Dedicated micro-drill holders
