Chipbreaker Profile
For micro-drill applications, the flute geometry acts as the primary chip evacuation system:
- Flute Form: Parabolic gullet optimized for 1.41 mm diameter
- Chip Evacuation: Helical flute with polished surface (Ra 0.1 μm) to prevent chip welding
- Chip Thinning: Rake angle 12° for reduced cutting forces and improved chip curl
- Edge Preparation: Micro-honing (0.01 mm) to enhance edge stability
Recommended Applications & Workpiece Materials
Primary Applications:
- Precision hole drilling in medical device components
- Micro-hole machining in aerospace fasteners
- Electronics industry connector pin holes
- Automotive fuel injection nozzle orifices
- Mold and die venting holes
Compatible Materials: Carbon steel, alloy steel, cast iron
Application Map by Operation
| Operation | Suitability | Notes |
|---|---|---|
| Through-hole Drilling | ★★★★★ | Optimal chip evacuation |
| Blind-hole Drilling | ★★★★☆ | Peck cycle recommended |
| Cross-hole Drilling | ★★★☆☆ | Reduce feed by 30% |
| Inclined Entry | ★★★☆☆ | Spot drill pre-stage advised |
Recommended Cutting Conditions
| Parameter | Value | Unit |
|---|---|---|
| Cutting Speed (Vc) | 80-120 | m/min |
| Feed per Revolution (fn) | 0.08-0.15 | mm/rev |
| Depth of Cut (ap) | 1.5-3.0×D | mm |
| Spindle Speed (n) | 18,060-27,090 | rpm |
| Coolant | Internal / External Mist | — |
Operating Guidelines
- Peck Cycle: For holes > 3×D, use 0.5×D peck depth with full retract to break chips
- Coolant Pressure: Minimum 20 bar for internal coolant to ensure chip evacuation
- Runout: Maintain TIR < 0.005 mm at tool tip for optimal tool life
- Pre-drilling: Not required for standard 140° point; use spot drill only for inclined surfaces
- Tool Life Indicator: Replace when flank wear (VB) exceeds 0.08 mm or when burr formation increases
