BEYOND HRC60 3D Coated Carbide Drill Bits (3.0-3.95mm) - 3xD Ultra-Hard Series for Demanding Machining
Engineered for robustness in critical applications, the BEYOND 3.0-3.95mm series represents the perfect balance of strength and precision. Combining an HRC60 ultra-hard tungsten carbide core with an advanced 3D coating and a reinforced 3x diameter flute length, this drill bit is built to deliver reliable, high-quality holes in the most challenging materials, from pre-hardened steels to abrasive cast iron.
Key Features & Benefits:
- HRC60 Ultra-Hard Tungsten Carbide: Offers exceptional wear resistance and edge retention, significantly outperforming HSS and standard carbide drills in high-hardness materials.
- Advanced 3D Coating (Bronze): Minimizes friction and heat buildup, prevents material adhesion, and extends tool life for more consistent performance over time.
- Reinforced 60° Point Angle & 3xD Flute Length: Ensures aggressive yet stable penetration, excellent centering, and efficient chip evacuation in deep-hole drilling operations.
- Robust Core & Precision Straight Shank: The thicker core diameter in this size range dramatically increases torsional strength, reducing the risk of breakage under high loads.
- Optimized for 3-4mm Range: Specifically engineered for stability in this critical diameter range, preventing deflection and ensuring hole accuracy.

| Drill Diameter (mm) | Recommended Speed (RPM) | Feed Rate (mm/rev) |
|---|---|---|
| 3.0 - 3.2 | 6,500 - 8,000 | 0.03 - 0.045 |
| 3.3 - 3.5 | 5,800 - 7,200 | 0.035 - 0.055 |
