Chipbreaker Profile
The D91 series features an optimized flute design with variable helix geometry to ensure efficient chip evacuation:
- Flute Profile: Parabolic flute for enhanced chip flow
- Core Thickness: 35% of tool diameter for maximum rigidity
- Margin Width: 0.15 mm per margin (dual margin design)
- Web Thinning: Advanced web thinning for reduced thrust force
- Chipbreaker Type: Natural parabolic chip formation (no additional breakers required)
- Surface Finish: Mirror-polished flutes (Ra 0.1 μm) to prevent built-up edge
Recommended Applications & Workpiece Materials
| Material Group | Machinability | Recommended |
|---|---|---|
| Carbon Steel (C < 0.5%) | ★★★★★ | Ideal |
| Alloy Steel (HB 180-280) | ★★★★☆ | Excellent |
| Stainless Steel (Austenitic) | ★★★★☆ | Very Good |
| Cast Iron (Grey/Ductile) | ★★★☆☆ | Good |
| Titanium Alloys | ★★★☆☆ | Moderate |
Application Map by Operation
| Operation Type | Suitability | Notes |
|---|---|---|
| Through-Hole Drilling | Primary Application | Optimal chip evacuation |
| Blind-Hole Drilling | Recommended | Peck cycle recommended |
| Deep Hole Drilling (L/D > 5) | Conditional | Use internal coolant |
| Micro-Drilling | Not Applicable | Diameter exceeds micro range |
Recommended Cutting Conditions
| Material | Cutting Speed (Vc) | Feed (fn) | Coolant |
|---|---|---|---|
| Low-Carbon Steel | 100-120 m/min | 0.15-0.25 mm/rev | Emulsion / MQL |
| Medium-Carbon Steel | 80-100 m/min | 0.12-0.20 mm/rev | Emulsion |
| Stainless Steel 304 | 60-80 m/min | 0.10-0.18 mm/rev | High-Pressure Emulsion |
| Alloy Steel 4140 | 70-90 m/min | 0.12-0.20 mm/rev | Emulsion / Oil |
Operating Guidelines
- Runout: Maintain TIR < 0.01 mm for optimal tool life and hole accuracy
- Coolant: Minimum 3-5% emulsion concentration; high-pressure (70+ bar) recommended for deep holes
- Peck Cycle: For depths > 3×D, use 1×D peck depth with full retract to break chips
- Entry Angle: Use chamfer or center drill to prevent walk; 90° entry preferred
- Speed Ramp: Reduce speed by 20% for first 10 holes to condition cutting edge
- Tool Change: Monitor flank wear; replace when VBmax = 0.3 mm or when burr formation appears
Toolholder Compatibility
| Holder Type | Compatibility | Notes |
|---|---|---|
| Hydraulic Chuck | ★★★★★ | Best damping, recommended |
| Shrink Fit | ★★★★★ | Excellent rigidity |
| ER Collet (ER25+) | ★★★★☆ | Ensure > 2/3 clamping length |
| Drill Chuck | ★★★☆☆ | Acceptable for short holes only |
