Grade Details - Key Grade Characteristics
TiAlN Coated Grade — This drill utilizes a tialn coated micro-grain carbide substrate engineered for optimal balance between hardness and toughness. The substrate features:
- Grain Size: 0.8 μm micro-grain structure for superior edge retention
- Coating: TiAlN Coated with 4-layer architecture for heat resistance and reduced friction
- Hardness: 92.5 HRA for extended wear resistance
- Transverse Rupture Strength: 3,200 N/mm² for impact resistance
- Application Range: Ideal for high-speed drilling operations
Grade Comparison Matrix
| Property | D90 2000 | Standard Grade | Performance Gain |
|---|---|---|---|
| Wear Resistance | Excellent | Good | +28% |
| Heat Resistance | Very Good | Fair | +33% |
| Chip Control | Excellent | Good | +22% |
| Surface Finish | Mirror | Standard | +46% |
Chipbreaker Profile
The D90 series features an optimized flute and point geometry designed for superior chip formation and evacuation:
- Flute Profile: Parabolic flute design with polished surface (Ra 0.2 μm) to minimize chip adhesion
- Chipbreaker Geometry: Continuous helical chip groove with medium land width for controlled chip curling
- Margin Design: Double margin with 0.15 mm width for hole wall stability and reduced friction
- Point Configuration: Standard chisel with web thinning for reduced thrust force and improved centering
- Coolant Channels: External coolant design for effective heat dissipation
Recommended Applications & Workpiece Materials
| Material | Hardness | Suitability | Notes |
|---|---|---|---|
| Carbon Steel | < 45 HRC | Excellent | High-speed drilling, general machining |
| Aluminum Alloy | Soft | Excellent | High-speed, polished flute recommended |
| Hardened Steel | 45-55 HRC | Good | Reduced feed, peck drilling cycle |
| Cast Iron | < 40 HRC | Excellent | Dry machining or minimal coolant |
Application Map by Operation
| Operation Type | Suitability | Recommended Conditions |
|---|---|---|
| Through-Hole Drilling | ★★★★★ | Standard parameters, through-coolant recommended |
| Blind-Hole Drilling | ★★★★★ | Peck cycle recommended for depths >3×D |
| High-Speed Drilling | ★★★★☆ | Vc 120-200 m/min, rigid setup required |
| Deep Hole Drilling (>5×D) | ★★★☆☆ | Step drilling or specialized deep-hole cycle |
| Micro-Drilling | ★★★☆☆ | Spindle speed >10,000 RPM, minimal runout |
Recommended Cutting Conditions
| Workpiece Material | Cutting Speed (Vc) | Feed per Rev (fn) | Coolant |
|---|---|---|---|
| Carbon Steel | 100-160 m/min | 0.19-21 mm/rev | Emulsion / Synthetic |
| Alloy Steel | 100-140 m/min | 0.11-30 mm/rev | Emulsion 8-10% |
| Stainless Steel | 40-120 m/min | 0.11-19 mm/rev | High-pressure coolant |
| Cast Iron | 120-120 m/min | 0.17-32 mm/rev | Dry / Minimal coolant |
| Aluminum Alloy | 150-350 m/min | 0.16-30 mm/rev | Air / MQL |
Note: Values are starting recommendations. Optimize based on machine rigidity, workpiece clamping, and hole depth requirements. For holes >3×D, reduce feed by 15-25%.
Operating Guidelines
- Runout Tolerance: Maximum tool runout should not exceed 0.02 mm at the cutting edge to prevent uneven wear and hole enlargement
- Peck Drilling: For holes deeper than 3×D, use a peck cycle with retract to break chips and allow coolant penetration
- Coolant Pressure: Minimum 5 bar recommended for through-coolant tools; ensure adequate flow rate for heat removal
- Tool Life Monitoring: Monitor flank wear (VB max = 0.3 mm) and replace before degradation affects hole quality
- Entry/Exit: Use chamfer or center drill for entry; reduce feed by 50% for exit to prevent burr formation
- Storage: Store in original packaging away from moisture and corrosive environments to preserve coating integrity
Toolholder Compatibility
| Holder Type | Compatibility | Notes |
|---|---|---|
| Hydraulic Chuck | Excellent | Best damping, ideal for high-speed applications |
| Shrink Fit Holder | Excellent | Maximum runout accuracy, rigid clamping |
| ER Collet Chuck | Very Good | Use precision collet (ER16/ER20/ER25) for best results |
| Milling Chuck | Good | Suitable for moderate speeds; verify clamping force |
| Drill Chuck (Keyless) | Good | Acceptable for manual/low-speed applications only |
