Chipbreaker Profile
The D88 series features an optimized chipbreaker geometry designed for reliable chip evacuation and reduced cutting forces:
- Chipbreaker Type: Double-margin with polished flutes
- Flute Profile: Parabolic flute design for enhanced chip flow
- Margin Width: 0.15 mm (narrow margin for reduced friction)
- Web Thickness: Tapered web (18% to 12% of diameter) for improved point strength
- Surface Finish: Mirror-polished flutes (Ra 0.2 μm) to prevent chip adhesion
- Edge Preparation: Light hone (0.02 mm) for edge stability and coating support

Application Map by Operation
| Operation | Suitability | Max Depth | Notes |
|---|---|---|---|
| Through-Hole Drilling | ★★★★★ | 3×D | Standard application, excellent chip control |
| Blind-Hole Drilling | ★★★★★ | 3×D | Reliable chip evacuation with peck cycle |
| Deep Hole Drilling | ★★★★☆ | 5×D | Use peck drilling cycle with internal coolant |
| Spot Drilling | ★★★★☆ | 0.5×D | Excellent centering accuracy |
| Counterboring | ★★★☆☆ | 1×D | Reduce feed by 30% for best results |
Recommended Cutting Conditions
Values are starting recommendations. Optimize based on machine rigidity, workpiece material, and coolant conditions.
| Material | Vc (m/min) | Feed f (mm/rev) | RPM | Coolant |
|---|---|---|---|---|
| Carbon Steel (C45) | 91 | 0.174 | 5352 | Emulsion 8-10% |
| Alloy Steel (42CrMo4) | 81 | 0.154 | 4709 | Emulsion 8-10% |
| Stainless Steel (304) | 68 | 0.143 | 4014 | Emulsion 10-12% |
| Stainless Steel (316) | 60 | 0.128 | 3492 | Emulsion 10-12% |
| Gray Cast Iron (GG25) | 111 | 0.194 | 6531 | Air / MQL |
Operating Guidelines
- Run-in Procedure: Reduce cutting speed by 20% for the first 50 holes to stabilize coating and edge
- Peck Drilling: For holes deeper than 3×D, use peck cycle with 1×D peck depth and full retract
- Coolant Pressure: Minimum 20 bar (290 psi) for through-tool coolant; 10 bar (145 psi) for external
- Coolant Concentration: 8-12% emulsion for steel; 10-15% for stainless steel
- Tool Life Indicator: Monitor flank wear (VB max 0.3 mm) and hole diameter deviation
- Re-sharpening: Not recommended for solid carbide drills; replace when worn
- Storage: Keep in original packaging; avoid contact with other tools to prevent edge chipping
Toolholder Compatibility
| Holder Type | DIN Standard | Clamping Range | Runout |
|---|---|---|---|
| Hydraulic Chuck | DIN 69871 | 5.4 mm | ≤ 3 μm |
| ER Collet (ER16/ER20) | DIN 6499 | 5.4 mm | ≤ 5 μm |
| Shrink Fit Holder | DIN 69893 | 5.4 mm | ≤ 3 μm |
| Drill Chuck (Keyless) | DIN 238 | 0.5-13 mm | ≤ 15 μm |
Recommendation: For optimal hole accuracy and tool life, use hydraulic chucks or shrink-fit holders with runout ≤ 5 μm at 3×D.
