BEYOND 6-7.9mm 3xD Coolant Through Carbide Drill Bits
Heavy-Duty 3xD Coolant Through Drills for Industrial Applications
BEYOND 6-7.9mm 3xD coolant through carbide drill bits are engineered for robust performance in demanding industrial machining applications. The 3x diameter length provides optimal stability and reach for deep hole drilling in hard materials, making these drills ideal for heavy-duty manufacturing environments.
With advanced internal coolant technology, these drills efficiently deliver high-pressure coolant to the cutting edge, dramatically reducing thermal stress and ensuring superior chip evacuation. The premium micro-grain carbide construction, combined with the optimized 140° point angle, delivers exceptional accuracy and extended tool life in materials up to HRC60 hardness.
Key Features & Benefits
3xD Optimal Length Ratio
3x diameter length provides the perfect balance between drilling depth and tool rigidity for stable performance in hard materials.
6-7.9mm Industrial Range
Comprehensive size coverage from 6.0mm to 7.9mm with standard 0.1mm increments for versatile industrial applications.
Advanced Coolant Delivery
Internal through-tool coolant system reduces heat generation by up to 40% and ensures efficient chip removal in deep holes.
HRC60+ Material Capability
Specifically engineered to efficiently machine hardened steels, tool steels, and super alloys with maximum productivity.
140° Optimized Point Angle
Advanced point geometry ensures excellent centering accuracy, reduces thrust force, and minimizes drill walking.
Industrial-Grade Carbide
