Chipbreaker Profile
This 2-flute 3×D design features an optimized point geometry with split-point grind for enhanced centering and reduced thrust forces. The extended flute profile ensures efficient chip evacuation in deep-hole applications.
| Chipbreaker Type | Standard 2-Flute Open Profile (3×D) |
| Chip Control | Excellent - optimized for deep-hole chip evacuation |
| Flute Form | Parabolic - optimized for rigidity and chip flow |
Recommended Applications & Workpiece Materials
Ideal for cr-mo steel, power gen alloys in aerospace sectors. This 3×D drill excels in:
- CNC machining centers with rigid toolholding
- High-precision deep-hole making (H7-H9 tolerance)
- Through-hole and blind-hole drilling up to 3×D depth
- Dry or MQL (Minimum Quantity Lubrication) machining
- High-volume production environments
Application Map by Operation
| Operation | Suitability | Notes |
|---|---|---|
| Through-Hole Drilling (3×D) | ★★★★★ | Excellent chip evacuation |
| Blind-Hole Drilling (3×D) | ★★★★☆ | Peck cycle recommended |
| Counter-Boring | ★★★☆☆ | Limited by point geometry |
| Spot Drilling | ★★★★☆ | Use rigid setup |
Recommended Cutting Conditions
| Material Group | Vc (m/min) | fn (mm/rev) | Coolant |
|---|---|---|---|
| Cr-Mo Steel | 68-120 | 0.054-0.172 | Emulsion / MQL |
| Stainless Steel | 58-105 | 0.054-0.138 | High-Pressure Coolant |
| Cast Iron | 88-150 | 0.054-0.172 | Dry / Air Blast |
Operating Guidelines
- Maximum hole depth: 3×D (three times drill diameter) — do not exceed without peck cycle
- Use rigid toolholding (HSK63A or higher recommended) to minimize runout
- Ensure workpiece clamping rigidity to prevent vibration and hole oversize
- For diameters below 1mm, reduce Vc by 20% and use peck drilling cycle
- Inspect drill point after every 50 holes in abrasive materials
- Store in original packaging to prevent edge damage
Toolholder Compatibility
| Shank Type | Cylindrical (h5 tolerance) |
| Recommended Collet | ER16, ER20, ER25 (precision grade AA) |
