BEYOND Tungsten Carbide Center Drill Type B 60° HRC55
Precision Center Drill for CNC and Engraving Machines
The BEYOND Tungsten Carbide Center Drill Type B 60° is designed for precise centering and chamfering before drilling. It provides excellent rigidity and durability, ideal for materials up to HRC55. Compared with Type A, the Type B design offers a longer guiding portion for better alignment and positioning.
Features
- Type B structure with enhanced guidance for stable drilling.
- 60° point angle for accurate positioning and reduced runout.
- Made of micro-grain tungsten carbide for high hardness and wear resistance.
- Designed for CNC machining centers and engraving machines.
- Provides excellent surface finish and hole accuracy.
Applicable Materials
Suitable for machining aluminum alloy, stainless steel, ductile cast iron, alloy steel, mold steel, and tempered steel. Stable cutting performance even in high-speed precision machining environments.
Recommended Machines
CNC machining centers, engraving machines, and precision milling machines. Not suitable for hand drills or low-rigidity devices.

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.
