BEYOND HRC60 3D Internal Coolant Solid Carbide Drill Bit 10–11.9mm – 140° Point Angle Extra Hard Straight Shank Twist Drill
Product Overview
The BEYOND HRC60 3D Internal Coolant Carbide Drill Bit is designed for precision CNC applications requiring high rigidity and smooth chip evacuation. It features internal coolant holes, a 140° point angle for accurate centering, and a 3×D drilling depth ratio for stable deep-hole drilling in hardened steel and alloys.
Key Features
- 3×D flute length (3 times the diameter) for efficient deep-hole drilling.
- 140° large point angle reduces cutting resistance and improves centering accuracy.
- Internal coolant design ensures effective cooling, chip removal, and extended tool life.
- Manufactured from ultra-fine HRC60 solid tungsten carbide for exceptional hardness and wear resistance.
- Suitable for CNC machining centers, drilling machines, and precision equipment.
Application Materials
- Hardened Steel (up to HRC60)
- Alloy Steel
- Tool Steel
- Stainless Steel
- Cast Iron / Ductile Iron
