Features:

1. 3D Flute Design for Enhanced Performance

Aggressive Chip Removal – Unique 3D spiral grooves prevent clogging, even in deep-hole drilling.
Reduced Cutting Forces – Smoother penetration in hard-to-machine materials.
Minimized Vibration – Improves hole accuracy and surface finish.

2. Solid Tungsten Carbide Construction

Extreme Hardness (90+ HRA) – Ideal for abrasive materials (cast iron, Inconel, hardened steels).
High Heat & Wear Resistance – Maintains sharpness longer than HSS or cobalt drills.

3. Specialized Coating (Optional)

AlTiN (Aluminum Titanium Nitride) – Best for high-temperature alloys (Inconel, Waspaloy).
TiCN (Titanium Carbo-Nitride) – Improves wear resistance in cast iron.
Uncoated (Polished) – For non-ferrous metals & general-purpose use.

4. Heavy-Duty Applications

✔ CNC machining, oil & gas, aerospace components
✔ Deep-hole drilling (up to 5× diameter)
✔ High-speed drilling in cast iron & superalloys
