- Coating: Multi-layer TiAlN-based PVD coating
- Hardness: 92.0 HRA (±0.5)
- Transverse Rupture Strength: 4,200 MPa
- Coating Thickness: 2.5 μm (±0.5)
- Coefficient of Friction: 0.35 (dry machining)
- Oxidation Resistance: Up to 1,100°C

Recommended Cutting Conditions
| Material | Cutting Speed Vc (m/min) | Feed fn (mm/rev) | Coolant |
|---|---|---|---|
| Low Carbon Steel | 80-120 | 0.15-0.25 | Emulsion / MQL |
| Medium Carbon Steel | 60-100 | 0.12-0.20 | Emulsion |
| Stainless Steel (Austenitic) | 40-70 | 0.10-0.18 | High-pressure coolant |
| Gray Cast Iron | 100-150 | 0.20-0.35 | Dry / Compressed air |
| Aluminum Alloy | 150-300 | 0.15-0.30 | MQL / Air blast |
| Titanium Alloy | 25-45 | 0.08-0.15 | High-pressure emulsion |
| Hardened Steel (45-55 HRC) | 20-40 | 0.05-0.12 | Oil-based coolant |
Note: Values are starting recommendations. Optimize based on machine rigidity, workpiece clamping, and desired surface finish. Reduce speeds by 20% for holes deeper than 3×D.
Operating Guidelines
- Runout Tolerance: Maintain TIR (Total Indicated Runout) below 0.01 mm at the tool tip for optimal tool life and hole accuracy.
- Coolant Pressure: For deep holes (>3×D), use minimum coolant pressure of 20 bar (290 psi) directed through the tool center.
- Peck Cycle: When drilling beyond 5×D, implement peck drilling with retract distance of 0.5-1.0 mm to facilitate chip evacuation.
- Entry Angle: Ensure perpendicular entry (±1°) or use a spot drill to prevent walk-off and chipping.
- Pre-drilling: For holes >10 mm or cross-drilling, consider a pilot hole of 0.5×D depth for guidance.
- Chip Control: Monitor chip shape; target C- or 6-shaped chips. Long stringy chips indicate insufficient feed or worn edges.
- Tool Change: Replace tool when flank wear exceeds 0.15 mm or when burr formation increases at hole exit.
Toolholder Compatibility
| Holder Type | Standard | Taper | Compatibility |
|---|---|---|---|
| Hydraulic Chuck | DIN 69871 | SK40 / SK50 | ★★★★★ Recommended |
| Shrink Fit Holder | DIN 69893 | HSK-A63 / HSK-A100 | ★★★★★ Recommended |
| Collet Chuck (ER) | DIN 6499 | ER25 / ER32 | ★★★★☆ Suitable |
| Milling Chuck | DIN 1835 | Weldon / Whistle Notch | ★★★★☆ Suitable |
| Drill Chuck (Keyless) | DIN 238 | B16 / B18 | ★★★☆☆ Not Recommended |
For best results, use hydraulic or shrink-fit holders to minimize runout and maximize tool life. Collet holders are acceptable for general applications but require careful torque management.
