BEYOND HRC60 3D Internal Coolant Solid Carbide Drill Bit 10–11.9mm – 140° Point Angle Extra Hard Straight Shank Twist Drill
Product Overview
The BEYOND HRC60 3D Internal Coolant Carbide Drill Bit is designed for precision CNC applications requiring high rigidity and smooth chip evacuation. It features internal coolant holes, a 140° point angle for accurate centering, and a 3×D drilling depth ratio for stable deep-hole drilling in hardened steel and alloys.
Key Features
- 3×D flute length (3 times the diameter) for efficient deep-hole drilling.
- 140° large point angle reduces cutting resistance and improves centering accuracy.
- Internal coolant design ensures effective cooling, chip removal, and extended tool life.
- Manufactured from ultra-fine HRC60 solid tungsten carbide for exceptional hardness and wear resistance.
- Suitable for CNC machining centers, drilling machines, and precision equipment.
Application Materials
- Hardened Steel (up to HRC60)
- Alloy Steel
- Tool Steel
- Stainless Steel
- Cast Iron / Ductile Iron

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.
