BEYOND HRC65 8D Solid Carbide Drill with Internal Coolant (19.0–20.0 mm)
The BEYOND HRC65 8D Solid Carbide Drill delivers extreme precision and durability for deep-hole drilling applications. Manufactured from ultra-fine carbide substrate and coated for superior wear resistance, this drill provides stable performance up to HRC65 materials. With internal coolant channels and an 8×D length-to-diameter design, it ensures efficient chip evacuation, lower cutting temperatures, and extended tool life.
🔧 Product Features
- Ultra-hard HRC65 carbide material — for cutting hardened steel, die steel, and alloy steel.
- 8×D long-length deep hole design — provides accuracy and rigidity in deep drilling.
- Internal coolant holes — improve chip evacuation and reduce heat for smoother drilling.
- Nano-coating technology — enhances wear resistance and prevents built-up edge.
- Precision-ground flutes — ensure optimal chip flow and superior hole surface finish.

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.
