BEYOND HRC65 8D Internal Coolant Solid Carbide Drill (13.0–14.9mm)
BEYOND HRC65 8D Solid Carbide Drills are engineered for deep-hole and high-precision drilling in hard and tough materials. Manufactured from premium fine-grain tungsten carbide and coated with a high-performance nano composite coating, they ensure stable cutting, superior heat resistance, and long service life even under high-speed machining conditions.
Features
- HRC65 ultra-hard carbide substrate – Perfect for hardened steel, die steel, and alloy steel.
- 8D (8×D) long drill design – Enables deep-hole machining with excellent straightness and stability.
- Internal coolant holes – Optimize chip evacuation and cooling during cutting, preventing tool wear.
- High-precision cutting edges – Reduce cutting force and burr formation for smooth hole finishes.
- Advanced TiAlN / Nano coating – Provides oxidation resistance and increases tool life by 2–3 times compared to uncoated tools.
Recommended Materials
Designed for drilling hardened steel (≤65HRC), die steel, cast iron, tool steel, and heat-treated alloy 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.
