Grade Comparison Matrix
| Property | GW15 | Standard Grade | Improvement |
| Wear Resistance | Excellent | Good | +35% tool life |
| Heat Resistance | Superior | Standard | +20% cutting speed |
| Chipping Resistance | High | Moderate | +40% edge stability |

Chipbreaker Profile
Precision-ground chip grooves with mirror-polished surfaces prevent chip welding and ensure reliable evacuation. The through-coolant (TD) design delivers coolant directly to the cutting edge at pressures up to 70 bar, ensuring effective temperature management and chip breaking even in blind-hole applications.
Recommended Applications & Workpiece Materials

| Aluminum 7075-T6 | Standard grades | Very Good | ✓ Primary |
| Copper C110 | Standard grades | Good | ✓ Recommended |
| Brass C360 | Standard grades | Good | ✓ Recommended |
| Magnesium AZ91D | Standard grades | Moderate | ○ Conditional |
Application Map by Operation
| Operation Type | Suitability | Depth Limit | Notes |
| Through-hole Drilling | ★★★★★ | 2.5×D | Optimal chip evacuation |
| Blind-hole Drilling | ★★★★☆ | 2.5×D | Use peck cycle for depths >3×D |
| Stack Drilling | ★★★★☆ | 2.5×D | Ensure adequate clamping |
| Cross-hole Drilling | ★★★☆☆ | 2×D | Reduce feed by 30% |
| Inclined Entry | ★★★☆☆ | 1.5×D | Max 15° inclination angle |
Recommended Cutting Conditions
| Parameter | Value Range | Optimal | Unit |
| Cutting Speed (Vc) | 70-110 | 70 | m/min |
| Feed per Revolution (fn) | 0.12-0.20 | 0.12 | mm/rev |
| Axial Depth (ap) | Up to 2.5×D | 1.5×D | × diameter |
| Spindle Speed (n) | 4,500-7,000 | 4,500 | rpm |
| Coolant Pressure | 20-70 | 40 | bar |
| Coolant Type | Emulsion / MQL | Emulsion 8-10% | - |
Operating Guidelines
- Always use through-coolant at minimum 20 bar pressure for optimal chip evacuation and tool life
- For depths exceeding 3×D, employ a peck drilling cycle with 1×D peck depth and 50% retract
- Maintain runout below 0.01 mm TIR to prevent premature corner wear and ensure hole straightness
- Verify workpiece clamping rigidity; minimum clamping force should resist 1.5× maximum thrust force
- When entering inclined surfaces, reduce feed to 50% for the first 0.5×D engagement depth
- Monitor spindle load; do not exceed 85% of rated spindle torque during drilling operations
- Replace tool when flank wear exceeds 0.15 mm or when burr formation increases significantly
