BEYOND 14-15.9mm 3xD Coolant Through Carbide Drill Bits
Heavy-Duty 3xD Coolant Through Drills with Robust D14/D16 Shanks
BEYOND 14-15.9mm 3xD coolant through carbide drill bits are engineered for the most demanding large-diameter drilling applications in heavy industry. Featuring robust D14 and D16 shank designs, these professional-grade tools deliver exceptional stability and precision in materials up to HRC60 hardness.
The advanced internal coolant system, combined with precision-ground 140° point angles, ensures efficient heat dissipation and superior chip evacuation. Manufactured from premium sub-micron grain carbide with TiAlN coating, these drills offer extended tool life and consistent performance in continuous production environments.
Key Features & Benefits
Large Diameter Industrial Range
14.0mm to 15.9mm complete size coverage with 0.1mm increments for precision large-scale drilling.
Robust Shank System
D14 (14mm) and D16 (16mm) shank diameters provide maximum stability and vibration damping.
Optimized 3xD Length
60-65mm flute length ensures ideal balance between drilling depth and tool rigidity.
HRC60+ Material Performance
Specially formulated carbide grade maintains cutting efficiency in hardened steels and super alloys.
140° Precision Point Geometry
Advanced point angle reduces thrust force and ensures accurate hole positioning in large diameters.
High-Pressure Coolant Ready
Internal coolant channels optimized for 30-50 bar pressure systems for maximum efficiency.
