Grade Details – Key Grade Characteristics
The PR1705 grade substrate is engineered from ultra-fine grain carbide (0.6 μm) for superior hardness and toughness balance. The Advanced PVD Coated layer provides:
- Exceptional wear resistance at elevated cutting temperatures
- Reduced built-up edge formation for improved surface integrity
- Enhanced lubricity minimizing friction coefficient during chip evacuation
- Superior adhesion strength preventing premature coating delamination
Grade Comparison Matrix
| Grade | Coating | Primary Application | Hardness Range |
| PR1535 | PVD (TiAlN) | Steel, Stainless Steel | Up to 35 HRC |
| PR1525 | CVD (TiCN-Al2O3) | Cast Iron, Low Alloy Steel | Up to 30 HRC |
| PR1705 | Advanced PVD | Hardened Steel, Alloy Steel | Up to 45 HRC |
Chipbreaker Profile
This drill features an optimized double-margin land design with polished flute surfaces to ensure smooth chip evacuation. The chipbreaker geometry is specifically tailored for the 6.30mm diameter range, providing:
- Controlled chip curl radius for reliable evacuation through internal coolant channels
- Reduced cutting forces minimizing deflection in deep-hole applications
- Stable chip formation across variable feed rates

| Cast Iron | GG25, GGG50 | ★★★★☆ Very Good |
| Hardened Steel | H13, D2, M2 (≤45 HRC) | ★★★☆☆ Good |
Application Map by Operation
| Operation Type | Capability | Max Depth |
| Through-Hole Drilling | Primary Application | 3×D |
| Blind-Hole Drilling | Recommended | 2.5×D |
| Stack Drilling | Suitable with Peck Cycle | 2×D per plate |
| Micro-Interruption | Limited Suitability | 1.5×D |
Recommended Cutting Conditions
| Workpiece Material | Cutting Speed (Vc) m/min | Feed (fn) mm/rev |
| Carbon Steel (≤30 HRC) | 109.1 | 0.102 |
| Alloy Steel (30-35 HRC) | 99.1 | 0.092 |
| Stainless Steel (Austenitic) | 74.4 | 0.102 |
| Cast Iron (Gray/Ductile) | 119.1 | 0.122 |
Operating Guidelines
- Always use through-tool coolant (minimum 20 bar pressure recommended) for optimal chip evacuation
- Ensure rigid toolholder setup with runout ≤0.01mm to maximize tool life
- Apply peck drilling cycle for depths exceeding 2.5×D to prevent chip packing
- Verify spindle speed calculation: RPM = (Vc × 1000) / (π × 6.30)
- Use high-quality cutting fluid with 8-10% concentration for steel and stainless steel
Toolholder Compatibility
This 6.30mm solid carbide drill is compatible with standard hydraulic chucks, shrink-fit holders, and high-precision collet chucks (ER16/ER20/ER25 depending on shank diameter). For best results, use:
- Hydraulic chucks (Hydrolock type) for vibration damping
- Shrink-fit holders for maximum rigidity in high-speed applications
- ER collet systems with ≤0.005mm runout for general purpose
