Chipbreaker Profile
The D90 series features an optimized dual-flute chipbreaker geometry engineered for superior chip evacuation and reduced cutting forces:
- Primary Rake Angle: 8° – 12° (positive) for reduced cutting pressure and minimized built-up edge
- Secondary Land: Polished margin land (0.15 mm width) ensures hole accuracy and surface finish
- Chip Flute Profile: Parabolic flute form with polished surface (Ra 0.2 µm) for efficient chip flow
- Edge Preparation: Micro-honed T-land (0.02–0.05 mm) enhances edge stability and prevents chipping
- Coolant Channels: Internal coolant holes (Ø0.8 mm) directed to the cutting lips for maximum heat dissipation

Application Map by Operation
| Operation Type | Suitability | Max Depth (D) | Notes |
|---|---|---|---|
| Through-hole Drilling | ★★★★★ Excellent | 5×D | Optimal chip evacuation |
| Blind-hole Drilling | ★★★★★ Excellent | 3×D | Use peck cycle for >2×D |
| Stack Drilling | ★★★★☆ Very Good | 2×D per plate | Ensure clamping rigidity |
| Cross-hole Drilling | ★★★☆☆ Good | 1.5×D | Reduce feed by 30% |
| Inclined Entry | ★★★☆☆ Good | 2×D | Use spot drill first; reduce Vc 20% |
Recommended Cutting Conditions
| Material | Cutting Speed Vc (m/min) | Feed fn (mm/rev) | Depth of Cut ap (mm) |
|---|---|---|---|
| Carbon Steel | 45-81 | 0.1-0.3 | 0.35 |
| Alloy Steel | 36-65 | 0.1-0.3 | 0.35 |
| Stainless Steel | 27-48 | 0.08-0.20 | 0.35 |
| Cast Iron | 50-91 | 0.1-0.3 | 0.35 |
| Aluminum Alloy | 113-203 | 0.15-0.35 | 0.35 |
Operating Guidelines
- Run-out Tolerance: Maintain tool run-out below 0.01 mm at the tool tip for optimal hole accuracy and tool life
- Coolant Recommendation: Use water-soluble coolant (6–8% concentration) at 8–12 bar pressure through internal channels
- Peck Cycle: For depths >2.5×D, employ peck drilling with 0.5×D peck depth and full retract to break chips
- Entry Surface: Ensure perpendicular entry or use a spot drill (90°–120°) to prevent walk and chipping
- Speed Ramp: Reduce spindle speed by 20% for the first 10 holes to condition the cutting edge
- Tool Change Criteria: Monitor hole diameter; replace when tolerance exceeds 70% of specified limit
- Storage: Store in original packaging at 15–25°C, humidity <60%, away from corrosive vapors
