Chipbreaker Profile
This 2-flute design features an optimized point geometry with thinned-web grind for enhanced centering and reduced thrust forces. The flute profile ensures efficient chip evacuation in blind-hole and through-hole applications.
| Chipbreaker Type | Standard 2-Flute Open Profile |
| Chip Control | Excellent - suitable for short-chip materials |
| Flute Form | Parabolic - optimized for rigidity |
Recommended Applications & Workpiece Materials
Ideal for mild steel, structural steel in medical sectors. This drill excels in:
- CNC machining centers with rigid toolholding
- High-precision hole making (H7-H9 tolerance)
- Through-hole and blind-hole drilling
- Dry or MQL (Minimum Quantity Lubrication) machining
- High-volume production environments
Application Map by Operation
| Operation | Suitability | Notes |
|---|---|---|
| Through-Hole Drilling | ★★★★★ | Excellent chip evacuation |
| Blind-Hole Drilling | ★★★★☆ | 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 |
|---|---|---|---|
| Mild Steel | 67-116 | 0.053-0.141 | Emulsion / MQL |
| Stainless Steel | 57-101 | 0.053-0.113 | High-Pressure Coolant |
| Cast Iron | 87-146 | 0.053-0.141 | Dry / Air Blast |
Operating Guidelines
- Maximum hole depth: 3×D (three times drill diameter) for optimal performance
- 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
