Grade Details - Key Grade Characteristics
TC Grade represents Tungsten Carbide substrate with high wear resistance and thermal stability. Ideal for high-speed machining of ferrous materials. The micro-grain carbide structure provides an optimal balance between hardness and toughness, enabling reliable performance under aggressive cutting parameters.
- Sub-micron grain carbide structure for superior edge retention
- AlTiN multi-layer PVD coating for enhanced heat resistance and reduced friction
- High hot hardness maintaining cutting edge integrity up to 1,100°C
- Optimized cobalt binder content for fracture resistance in interrupted cuts
- Low affinity to ferrous materials minimizing built-up edge formation

Chipbreaker Profile
The 2fl flute geometry of the SGS57735 is engineered with a proprietary chipbreaker profile that promotes efficient chip formation and evacuation. The flute design features:
- Parabolic flute form maximizing core strength while maintaining chip flow capacity
- Polished flute surface (Ra 0.2 μm) reducing chip adhesion and friction
- Optimized flute depth-to-width ratio for balanced chip curling and evacuation
- Reinforced core diameter providing rigidity for deep-hole drilling up to 5×D
- Variable helix angle design minimizing harmonic vibration and chatter

Recommended Cutting Conditions
| Material | Cutting Speed Vc (m/min) | Feed fn (mm/rev) | Coolant |
|---|---|---|---|
| Carbon Steel | 40–80 | 0.05–0.15 | Emulsion / MQL |
| Alloy Steel | 30–70 | 0.05–0.13 | Emulsion recommended |

| Aluminum | 120–180 | 0.10–0.20 | MQL / Air blast |
Operating Guidelines
- Ensure workpiece is rigidly clamped with minimal overhang to prevent vibration and tool deflection
- Use high-quality collet or hydraulic chuck with TIR ≤ 0.01 mm for optimal hole accuracy
- Maintain coolant concentration at 8–10% for water-based emulsions to prevent thermal cracking
- Implement peck drilling cycle for holes deeper than 3×D to ensure chip evacuation and prevent packing
- Monitor tool wear by checking corner radius; regrind or replace when flank wear exceeds 0.15 mm
- Reduce cutting speed by 15% when entering cross-holes or interrupted cuts to prevent chipping
- Always start with manufacturer-recommended parameters and optimize based on machine rigidity and setup
