Grade Details — Key Grade Characteristics
Grade TC is a high-performance submicron cemented carbide specifically developed for solid drilling applications. It combines a 8% cobalt binder with ultra-fine tungsten carbide grains (0.5–0.8 μm) to achieve the optimal balance between hardness and toughness.
- Coating: Multi-layer TiAlN-based PVD coating for enhanced heat resistance and reduced friction
- Hardness: 92.5 HRA (±0.5)
- Transverse Rupture Strength: >3,800 MPa
- Operating Temperature: Up to 900°C in the cutting zone
- Primary Application: Medium to high-speed drilling in steels, stainless steels, and cast irons
Grade Comparison Matrix

| Hardness (HRA) | 92.5 | 91.0 | 91.8 |
| Wear Resistance | Excellent ★★★★★ | Good ★★★☆☆ | Very Good ★★★★☆ |
| Toughness | Very Good ★★★★☆ | Excellent ★★★★★ | Good ★★★☆☆ |
| Heat Resistance | 900°C | 600°C | 750°C |
| Recommended Vc (Steel) | 80–120 m/min | 40–60 m/min | 60–90 m/min |
Chipbreaker Profile
The 5.7mm 2-flute geometry features a variable helix design with polished flute surfaces to ensure efficient chip evacuation and minimize built-up edge. The flute profile is optimized for:
- Chip Forming: Controlled curl radius for short, manageable chip segments
- Evacuation: Wide flute gullets with polished surface finish (Ra 0.2 μm)
- Stability: Balanced cutting forces reduce vibration and improve hole straightness
- Margin Design: Dual narrow margins for precise hole sizing and reduced friction
Recommended Applications & Workpiece Materials
| Material Group | ISO Code | Suitability | Notes |
|---|---|---|---|
| Low & Medium Carbon Steel | P.1–P.3 | ★★★★★ Excellent | High-speed capable, long tool life |
| Alloy Steel & Hardened Steel (<45 HRC) | P.4–P.5 | ★★★★☆ Very Good | Reduce Vc by 15% for >35 HRC |
| Austenitic Stainless Steel | M.1–M.2 | ★★★★☆ Very Good | Ensure adequate coolant flow |
| Gray & Ductile Cast Iron | K.1–K.3 | ★★★★★ Excellent | Dry or MQL machining possible |
| Aluminum & Alloys | N.1–N.3 | ★★★☆☆ Good | Use polished flutes to prevent built-up edge |
| Titanium & High-Temp Alloys | S.1–S.2 | ★★☆☆☆ Limited | Reduce speeds by 40%; not recommended for deep holes |
Application Map by Operation
| Operation Type | Suitability | Max Depth | Recommended Conditions |
|---|---|---|---|
| Through-Hole Drilling | ★★★★★ Excellent | 3×D | Standard peck cycle for >2.5×D |
| Blind-Hole Drilling | ★★★★☆ Very Good | 2.5×D | Reduce feed 20% in last 1 mm |
| Stack Drilling | ★★★☆☆ Good | — | Clamp stack firmly; watch for burr formation |
| Micro-Drilling / Engraving | ★☆☆☆☆ Not Recommended | — | Diameter too large for micro applications |
| Trepanning / Core Drilling | ★☆☆☆☆ Not Recommended | — | Use dedicated core drills for this operation |
Recommended Cutting Conditions
Values calculated for 5.7mm diameter. Adjust based on machine rigidity, coolant delivery, and workpiece fixturing.
| Workpiece Material | Cutting Speed (Vc) | Feed per Rev (fn) | Spindle Speed (n) | Feed Rate (Vf) |
|---|---|---|---|---|
| Steel (P) | 100 m/min | 0.15 mm/rev | 5,584 RPM | 837.6 mm/min |
| Stainless Steel (M) | 80 m/min | 0.12 mm/rev | 4,467 RPM | 536.0 mm/min |
| Cast Iron (K) | 120 m/min | 0.18 mm/rev | 6,701 RPM | 1206.2 mm/min |
| Aluminum (N) | 250 m/min | 0.25 mm/rev | 13,960 RPM | 3490.0 mm/min |
Operating Guidelines
- Coolant: High-pressure coolant (70–100 bar) is strongly recommended for holes deeper than 2×D. Use water-miscible cutting fluid with 8–10% concentration.
- Peck Cycle: For depths exceeding 2.5×D, implement a peck drilling cycle with 0.5×D peck depth and full retract to break chips.
- Entry Angle: Ensure perpendicular entry (±1°) to prevent chipping of the drill corners. Use a center drill or spot drill for irregular surfaces.
- Exit Strategy: Reduce feed rate by 30% when approaching through-hole breakthrough to minimize burr formation and corner damage.
- Tool Life Check: Monitor flank wear on the outer corners. Regrind or replace when wear land exceeds 0.3 mm or when hole tolerance begins to drift.
- Speed & Feed Ramp: Start at the lower end of the recommended range and increase gradually while monitoring tool temperature and chip color.
