Chipbreaker Profile
The SGS56151 features a proprietary GH - High-feed chipbreaker for stable machining optimized for alloy steel (≤ 55 hrc) machining. The flute geometry incorporates a variable helix design that reduces harmonic vibration and promotes stable chip formation. Wide, polished flutes ensure rapid chip evacuation, preventing recutting and extending tool life.
| Feature | Benefit |
|---|---|
| Variable Helix Angle | Reduces chatter and vibration in high-speed drilling |
| Polished Flute Surface | Minimizes chip adhesion and built-up edge formation |
| Reinforced Core | Enhanced torsional rigidity for stable hole accuracy |
| Self-Centering Point | Eliminates wandering on inclined or curved entry surfaces |
Recommended Applications & Workpiece Materials
High-speed machining of steel and cast iron. Optimized for production environments requiring maximum metal removal rates.
| Material Group | Examples | Hardness Range | Machinability |
|---|---|---|---|
| Carbon Steel | C45, C50, 1045, 1050 | ≤ 250 HB | Excellent |
| Alloy Steel | 4140, 4340, 16MnCr5 | ≤ 300 HB | Very Good |
| Stainless Steel | 304, 316, 17-4PH | ≤ 280 HB | Good |
| Cast Iron | GG25, GG30, GGG40 | ≤ 260 HB | Excellent |
| Hardened Steel | H13, D2, M2 | 45-60 HRC | Good (PR1535 only) |
Application Map by Operation
| Operation Type | Suitability | Notes |
|---|---|---|
| General Drilling | ★★★★★ | Balanced performance across materials |
| Semi-Finishing | ★★★★☆ | Good surface finish (Ra 0.8-1.6 μm) |
| Blind Holes | ★★★★☆ | Effective bottom chip control |
Recommended Cutting Conditions
| Parameter | Min | Max | Unit |
|---|---|---|---|
| Cutting Speed (Vc) | 100 | 150 | m/min |
| Feed per Revolution (fn) | 0.08 | 0.2 | mm/rev |
| Spindle Speed (n) | 4221 | 6332 | RPM |
| Depth of Cut (ap) | 7.54 | 7.54 | mm (full diameter) |
| Max Hole Depth | - | 18.9 | mm (3xD standard) |
Note: Start at the lower end of the parameter range and increase gradually based on machine stability and chip formation. Use internal coolant (10-15% emulsion or MQL) for optimal performance.
Operating Guidelines
- Ensure workpiece clamping rigidity to prevent vibration and hole oversize.
- Use through-spindle coolant at minimum 20 bar pressure for holes deeper than 2xD.
- Peck drilling recommended for depths exceeding 3x cutting diameter.
- Maintain toolholder TIR below 0.01 mm for holes requiring H7 tolerance.
- Replace drill when flank wear exceeds 0.15 mm to maintain surface finish.
- Pre-drill pilot hole (1xD depth, 0.2 mm larger point diameter) for inclined entries >5°.
Toolholder Compatibility
High-precision hydraulic chucks, shrink-fit holders, and milling chucks with TIR ≤ 0.005 mm recommended
| Holder Type | Recommended For | Max Runout |
|---|---|---|
| ER Collet Chuck | General purpose, flexible clamping | ≤ 0.015 mm |
| Hydraulic Chuck | High precision, dampening | ≤ 0.005 mm |
