BEYOND 2-2.9mm 3xD Coolant Through Carbide Drill Bits - HRC60 Hardness
Precision Micro-Drilling for Demanding Applications
BEYOND 3xD Coolant Through Hole Carbide Drill Bits in 2.0mm to 2.9mm diameters are engineered for high-performance micro-deep hole drilling in tough materials up to HRC60 and beyond. The innovative internal coolant channel design is critical at this small scale, effectively reducing heat buildup—the primary cause of tool failure—and ensuring efficient chip evacuation in deep-hole operations.
The robust 140° point angle provides excellent centering accuracy and minimizes walking and vibration, which is paramount when drilling small, precise holes. Made from premium micro-grain carbide, these drills offer exceptional wear resistance and durability, making them the ideal choice for the mold, electronics, and medical industries where precision is non-negotiable.
Key Features & Benefits
- Micro-Diameter Range (2.0mm - 2.9mm): Specifically designed for precision small hole drilling applications.
- 3x Diameter (3xD) Length: Provides the necessary reach for deep hole drilling where standard length drills are insufficient.
- Internal Coolant Through Holes: Delivers coolant directly to the cutting edge, reducing thermal stress, improving tool life, and enhancing chip evacuation in deep, small-diameter holes.
- HRC60+ Hardness Rating: Built to tackle hardened steels, alloy steels, and other difficult-to-machine materials.
- 140° Point Angle: Provides superior stability, reduces thrust force, and prevents walking for precise hole positioning.
- Premium Carbide Substrate: Ensures maximum rigidity, wear resistance, and overall longevity compared to HSS drills.
- Straight Shank Design: Guarantees secure and easy clamping in standard CNC tool holders and collets.
