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.

Technical FAQ & Buying Guide
Absolutely. Our CNC carbide inserts (including CNMG, WNMG, DNMG, and APMT series) are manufactured strictly adhering to international ISO/ANSI specifications. A CNMG 120408 from OYYU BEYOND will flawlessly fit any standard turning tool holder or indexable tool from major global brands like Sandvik Coromant, Kennametal, Iscar, Walter, or SECO, providing a highly cost-effective premium alternative without sacrificing tolerance or tool life.
We offer optimized CVD and PVD multi-layer coatings for different ISO material groups:
- For Carbon/Alloy Steel (ISO P): Choose our thick multi-layer CVD coated grades (e.g., Al2O3 + TiN). They provide exceptional crater wear resistance and thermal barriers during high-speed dry or wet roughing.
- For Stainless Steel (ISO M): Choose our nano-structured PVD coated grades with sharp, positive chipbreakers (like -TM or -MA). This combination prevents work hardening and effectively controls sticky chips.
The optimal cutting parameters vary depending on the workpiece hardness and operation type:
- For General Steel Turnings: Recommended cutting speed ($V_c$) ranges from 150 to 280 m/min, with a feed rate ($f$) of 0.15 to 0.45 mm/rev.
- For Stainless Steel Finishing: Recommended cutting speed ($V_c$) is 120 to 200 m/min, with a feed rate ($f$) of 0.10 to 0.25 mm/rev.Always adjust parameters based on early wear patterns: increase $V_c$ if built-up edge occurs, or reduce $V_c$ if severe flank wear is observed.
