Grade Details - Key Grade Characteristics
Grade TC is a premium micro-grain carbide substrate engineered for exceptional wear resistance and thermal stability in high-speed drilling applications.
- Substrate: Ultra-fine tungsten carbide (0.5–0.8 μm grain size)
- Coating: Advanced PVD multi-layer coating for reduced friction and heat dissipation
- Hardness: 1,650 HV (Vickers)
- TRS: >4,200 MPa (transverse rupture strength)
- Operating Temp: Up to 800°C intermittent
Grade Comparison Matrix
| Property | Grade TC | Standard Grade |
| Wear Resistance | ★★★★★ | ★★★☆☆ |
| Toughness | ★★★★☆ | ★★★☆☆ |
| Heat Resistance | ★★★★★ | ★★★☆☆ |
| Coating Adhesion | ★★★★★ | ★★★★☆ |
Chipbreaker Profile
The optimized flute geometry and point design ensure efficient chip formation and evacuation, minimizing built-up edge and improving hole quality.
- Chipbreaker Type: Continuous helical flute with polished gash
- Chip Form: Controlled 6–9 mm C-shaped chips for steel; 3–6 mm for stainless
- Surface Finish: Mirror-polished flutes (Ra < 0.2 μm) to reduce adhesion
- Edge Preparation: Honing (T-land) for enhanced edge stability
Recommended Applications & Workpiece Materials
| Material Group | ISO Code | Machinability |
| Low-alloy / Carbon Steel | P.1 – P.3 | Excellent |
| Stainless Steel (Austenitic) | M.1 – M.2 | Good |
| Cast Iron (Grey / Ductile) | K.1 – K.3 | Excellent |
| Titanium Alloys | S.1 – S.2 | Good |
| High-temp Alloys (Ni-based) | S.3 | Moderate |
Application Map by Operation
| Operation | Suitability | Notes |
| Through-hole Drilling | Recommended | Optimal chip evacuation |
| Blind-hole Drilling | Recommended | Peck cycle recommended >2×D |
| Stack Drilling | Conditional | Reduce feed by 15% |
| Micro-drilling | Recommended | Rigid setup required |
Recommended Cutting Conditions
| Material | Cutting Speed (Vc) | Feed per Rev (fn) |
| Carbon Steel | 60 – 90 m/min | 0.10 – 0.18 mm/rev |
| Alloy Steel | 50 – 80 m/min | 0.08 – 0.15 mm/rev |
| Stainless Steel | 40 – 60 m/min | 0.08 – 0.12 mm/rev |
| Cast Iron | 70 – 100 m/min | 0.12 – 0.20 mm/rev |
| Aluminum Alloy | 100 – 150 m/min | 0.15 – 0.25 mm/rev |
Operating Guidelines
- Use high-pressure coolant (minimum 70 bar) for holes deeper than 3×D to ensure chip evacuation.
- Maintain runout below 0.02 mm TIR for diameters ≤ 3 mm; below 0.03 mm for larger diameters.
- Peck drilling cycle recommended for blind holes >2×D depth to prevent chip packing.
- Ensure rigid workpiece clamping and minimal overhang to avoid vibration and chatter.
- Inspect cutting edges before each use; do not re-sharpen coated drills.
Toolholder Compatibility
| Holder Type | Compatibility | Recommendation |
| Hydraulic Chuck | Universal | Best for <6 mm diameters |
| ER Collet Chuck | Universal | Use ER16–ER25 precision collets |
| Shrink Fit Chuck | Universal | Recommended for high-speed |
| Weldon Shank Holder | Not applicable | Cylindrical shank only |
