Chipbreaker Profile
The SGM06157 features an optimized variable-helix flute geometry with a laser-etched surface finish. The chipbreaker design ensures:
- Controlled chip curling radius of 4.6–7.0 mm
- Chip thickness reduction of 18% compared to standard geometries
- Enhanced chip evacuation through variable flute spacing
- Reduced built-up edge (BUE) formation on tool steel workpieces
Recommended Applications & Workpiece Materials

Application Map by Operation
| Operation Type | Suitability | Max Depth (×D) | Notes |
|---|---|---|---|
| Through-Hole Drilling | ★★★★★ Recommended | 3×D – 5×D | Optimal chip evacuation |
| Blind-Hole Drilling | ★★★★☆ Suitable | 2×D – 3×D | Use peck cycle recommended |
| Stack Drilling | ★★★☆☆ Possible | 1×D – 2×D | Clamp workpiece securely |
| Micro-Drilling | ★★★★☆ Suitable | 1×D – 2×D | High spindle speed required |
| Enlarging / Reaming | ★★☆☆☆ Not Recommended | — | Use dedicated reamer |
Recommended Cutting Conditions
| Workpiece Material | Cutting Speed Vc (m/min) | Feed fn (mm/rev) | Coolant |
|---|---|---|---|
| Mild Steel (P.1) | 92.0 | 0.216 | Emulsion (8%) |
| Stainless Steel (M.1) | 46.0 | 0.167 | Emulsion (10%) + EP |
| Cast Iron (K.1) | 69.0 | 0.224 | Dry / MQL |
| Alloy Steel (P.4) | 78.0 | 0.194 | Emulsion (8%) |
| Tool Steel (P.7) | 55.0 | 0.162 | Emulsion (10%) + EP |
Note: Values are starting recommendations. Optimize based on machine rigidity, workpiece clamping, and surface finish requirements. Reduce Vc by 15% for blind holes.
Operating Guidelines
- Spindle Speed (n): Calculate using n = (Vc × 1000) / (π × D). For 5,8mm at 92.0 m/min: 5049 RPM
- Feed Rate (vf): vf = fn × n. At 0.216 mm/rev: 1090.6 mm/min
- Peck Cycle: For depths > 2×D, use peck depth of 0.5×D to 1.0×D with full retract
- Coolant Pressure: Maintain 10–15 bar for through-tool coolant systems
- Run-out Tolerance: Keep tool run-out below 0.116 mm (2% of diameter) at the tool tip
- Pre-drilling: Not required for 5,8mm; tool is self-centering with 140° point angle
- Tool Life Monitoring: Expected tool life: 20–30 min in continuous steel cutting
Toolholder Compatibility
| Holder Type | Standard | Clamp Method | Compatibility |
|---|---|---|---|
| Hydraulic Chuck | DIN 69871 | Hydraulic clamp | ★★★★★ Excellent |
| Shrink Fit Holder | ISO 12164 | Thermal shrink | ★★★★★ Excellent |
| ER Collet Chuck | DIN 6499 | Collet clamp | ★★★★☆ Very Good |
| Milling Chuck | DIN 1835 | Wedge clamp | ★★★☆☆ Good |
| Drill Chuck | DIN 238 | Keyless/keyed | ★★☆☆☆ Limited |
For optimal performance, use hydraulic or shrink-fit holders with HSK-A63 or BT40 taper interfaces. Ensure TIR (Total Indicator Reading) does not exceed 0.005 mm at 3×D projection.
