Chipbreaker Profile
The SGS56112 features an optimized chipbreaker geometry designed for 3/16" imperial drilling applications. The flute profile incorporates a variable helix design with polished rake surfaces to minimize built-up edge and ensure smooth chip flow. The narrow land width and increased clearance angle promote efficient chip curling and breakage, reducing the risk of chip packing in deep-hole applications.
- Variable helix angle reduces harmonics and vibration
- Polished flute surface (Ra 0.2 μm) minimizes friction
- Optimized chipbreaker width for consistent chip segmentation
- Reinforced cutting edge margin for improved stability

Application Map by Operation
| Operation Type | Depth Ratio | Hole Quality | Recommended |
|---|---|---|---|
| Through-hole Drilling | 2D - 5D | IT8 - IT9 | ✓ Primary Application |
| Blind-hole Drilling | 2D - 4D | IT9 - IT10 | ✓ Recommended |
| Stack Drilling | Variable | IT10 - IT11 | ✓ Suitable |
| Cross-hole Drilling | 2D - 3D | IT9 - IT10 | ✓ With reduced feed |
Recommended Cutting Conditions
| Material | Cutting Speed (Vc) | Feed Rate (fn) | Coolant |
|---|---|---|---|
| Carbon Steel | 100-150 m/min | 0.12-0.35 mm/rev | Emulsion / MQL |
| Alloy Steel | 70-110 m/min | 0.1-0.28 mm/rev | Emulsion / Oil |
| Stainless Steel | 50-80 m/min | 0.08-0.22 mm/rev | Oil / Emulsion |
| Cast Iron | 90-140 m/min | 0.12-0.32 mm/rev | Dry / Air Blast |
Operating Guidelines
- Ensure proper toolholder runout < 0.01 mm to maximize tool life and hole accuracy
- Use recommended coolant pressure (≥ 20 bar) for deep-hole applications (> 3D)
- Maintain consistent feed rate; avoid dwell at hole bottom to prevent work-hardening
- Peck drilling recommended for depths exceeding 3× drill diameter
- Inspect cutting edges before each shift; replace immediately upon chipping detection
- Store in original packaging away from corrosive environments
