BEYOND HRC60 3D Coated Carbide Drill Bits (7.0-7.95mm) - Heavy-Duty Performance for Industrial Applications
Meet the industrial workhorse for demanding drilling applications. The BEYOND 7.0-7.95mm series combines robust construction with advanced 140° point angle technology to deliver exceptional performance in the most challenging materials. Featuring an HRC60 ultra-hard tungsten carbide core and premium 3D coating, these drills are engineered for high-volume production environments where reliability, precision, and cost-efficiency are critical.
Key Features & Benefits:
- Industrial-Grade 140° Point Angle: Dramatically reduces thrust force by up to 65%, enabling higher feed rates and eliminating work hardening in stainless steels and high-temperature alloys.
- HRC60 Ultra-Hard Tungsten Carbide: Exceptional wear resistance and edge retention for extended tool life in abrasive materials, significantly reducing cost per hole in production runs.
- Advanced 3D Multi-Layer Coating: Superior thermal barrier properties reduce friction and heat generation, preventing material adhesion and extending tool life in continuous operation.
- Reinforced Core & 3xD Flute Design: Enhanced web thickness and optimized flute geometry provide maximum rigidity and efficient chip evacuation in deep-hole applications.
- Production-Optimized Geometry: Specifically engineered for the 7-8mm range with balanced chipbreaker design that prevents chip packing in stringy materials.

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.
