Chipbreaker Profile
The SGS56138 features a proprietary JM - General purpose chipbreaker for medium cutting optimized for carbon steel (≤ 45 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
General machining of carbon steel, alloy steel, and stainless steel. Ideal for through-hole and blind-hole drilling operations.
| 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 |
|---|---|---|
| Micro-Drilling | ★★★★★ | Excellent chip evacuation at high RPM |
| Precision Holes | ★★★★★ | Tight tolerance capability (H7-H8) |
| Through-Holes | ★★★★☆ | Stable exit with reduced burr |
Recommended Cutting Conditions
| Parameter | Min | Max | Unit |
|---|---|---|---|
| Cutting Speed (Vc) | 80 | 120 | m/min |
| Feed per Revolution (fn) | 0.05 | 0.15 | mm/rev |
| Spindle Speed (n) | 10699 | 16049 | RPM |
| Depth of Cut (ap) | 2.38 | 2.38 | mm (full diameter) |
| Max Hole Depth | - | 8.3 | 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
Standard collet chucks (ER16, ER20, ER25), hydraulic chucks, and shrink-fit holders with minimum TIR ≤ 0.01 mm
| Holder Type | Recommended For | Max Runout |
|---|---|---|
| ER Collet Chuck | General purpose, flexible clamping | ≤ 0.015 mm |
| Hydraulic Chuck | High precision, dampening | ≤ 0.005 mm |
| Shrink-Fit Holder | Maximum rigidity, high-speed | ≤ 0.003 mm |
| Milling Chuck | Heavy-duty, high torque | ≤ 0.010 mm |
