BEYOND HRC60 5D Carbide Drill Bits (5.0-6.9mm) - Industrial-Grade Deep Hole Drilling Performance
Master challenging deep hole applications with the BEYOND 5.0-6.9mm 5D series. Engineered with an advanced 140° point angle and exceptional 5x diameter flute length, these HRC60 carbide drills deliver reliable performance in deep cavity drilling operations. Perfect for mold manufacturing, hydraulic components, and aerospace structures where extended reach and precision are paramount.
Key Features & Benefits:
- Extended 5xD Flute Length: Unmatched 5:1 depth-to-diameter ratio enables drilling deep cavities up to 34.5mm, eliminating the need for specialized deep-hole drilling equipment in many applications.
- Optimized 140° Point Angle: Wide point geometry reduces thrust force by 50-60%, ensures excellent centering accuracy, and prevents walking on curved or angled surfaces.
- HRC60 Ultra-Hard Tungsten Carbide: Superior wear resistance and structural integrity maintain dimensional stability throughout extended deep-hole operations in abrasive materials.
- Reinforced Core Design: Enhanced web thickness and optimized flute geometry provide maximum torsional strength, reducing deflection and breakage risk in deep-hole applications.
- Precision Ground Flutes: Specialized helix angle and rake geometry ensure efficient chip evacuation, preventing chip packing and tool failure in extended reach drilling.

Deep Hole Drilling Tip: Use peck drilling cycles (G83) with retractions every 1-1.5x diameter for effective chip breaking. Maintain high-pressure coolant flow (minimum 15 bar) through the tool. Reduce feed rates by 25% when approaching maximum depth. Ensure perfect tool holder alignment to minimize runout and deflection.

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.
