BEYOND HRC60 5D Carbide Drill Bits (1.0-4.9mm) - Ultra-Long Reach for Precision Deep Hole Drilling
Experience unparalleled deep hole drilling performance with the BEYOND 1.0-4.9mm 5D series. Featuring an innovative 140° point angle and extraordinary 5x diameter flute length, these ultra-hard HRC60 carbide drills are engineered for precision drilling in deep cavity applications. Perfect for mold making, aerospace components, and medical instruments where depth-to-diameter ratio is critical.
Key Features & Benefits:
- Ultra-Long 5xD Flute Length: Exceptional 5:1 depth-to-diameter ratio enables drilling deep cavities and holes that conventional drills cannot reach, eliminating the need for specialized deep-hole equipment.
- Optimized 140° Point Angle Design: Wide point angle reduces thrust force by up to 60%, prevents walking, and ensures excellent centering for precise hole starting in curved or angled surfaces.
- HRC60 Ultra-Hard Tungsten Carbide: Superior wear resistance and rigidity maintain dimensional accuracy throughout extended deep-hole drilling operations, even in abrasive materials.
- Advanced Micro-Grain Carbide Structure: Fine-grained carbide substrate provides exceptional toughness and shock resistance, reducing breakage risk in extended-length drilling applications.
- Precision Ground Flute Geometry: Specially designed helix angle and web thickness optimize chip evacuation in deep holes, preventing chip packing and tool breakage.
