BEYOND HRC60 3D Coated Carbide Drill Bits (4.0-4.95mm) - 140° Point Angle for Superior Performance in Tough Materials
Experience drilling redefined with the BEYOND 4.0-4.95mm series featuring an innovative 140° point angle. This advanced geometry, combined with an HRC60 ultra-hard tungsten carbide core and 3D coating, is specifically engineered for challenging materials like stainless steel, high-temperature alloys, and hardened steels. The obtuse point angle reduces axial thrust force, minimizes walking, and prevents work hardening - delivering cleaner, more accurate holes with extended tool life.
Key Features & Benefits:
- Optimized 140° Point Angle: Significantly reduces thrust force by up to 40% compared to standard points, preventing work hardening in stainless steels and minimizing burr formation.
- HRC60 Ultra-Hard Tungsten Carbide: Exceptional wear resistance for extended tool life in abrasive and high-hardness materials, reducing tooling costs and machine downtime.
- Advanced 3D Coating (Bronze): Superior thermal barrier reduces friction and heat generation, particularly beneficial when drilling heat-resistant alloys and stainless steels.
- Enhanced Stability with 3xD Flute Length: Provides the perfect balance between depth capability and rigidity, ensuring straight, accurate holes in deep-hole applications.
- Stainless Steel Optimized Geometry: Specifically designed for stringy materials with specialized flute geometry that ensures efficient chip evacuation and prevents chip packing.

Technical Cutting Data Reference:
Optimized for stainless steel, high-temperature alloys, and work-hardening materials.
| Drill Diameter (mm) | Recommended Speed (RPM) | Feed Rate (mm/rev) |
|---|---|---|
| 4.0 - 4.2 | 3,800 - 4,800 | 0.04 - 0.06 |
| 4.3 - 4.5 | 3,400 - 4,300 | 0.045 - 0.065 |
