BEYOND HRC60 3D Coated Carbide Drill Bits (3.0-3.95mm) - 3xD Ultra-Hard Series for Demanding Machining
Engineered for robustness in critical applications, the BEYOND 3.0-3.95mm series represents the perfect balance of strength and precision. Combining an HRC60 ultra-hard tungsten carbide core with an advanced 3D coating and a reinforced 3x diameter flute length, this drill bit is built to deliver reliable, high-quality holes in the most challenging materials, from pre-hardened steels to abrasive cast iron.
Key Features & Benefits:
- HRC60 Ultra-Hard Tungsten Carbide: Offers exceptional wear resistance and edge retention, significantly outperforming HSS and standard carbide drills in high-hardness materials.
- Advanced 3D Coating (Bronze): Minimizes friction and heat buildup, prevents material adhesion, and extends tool life for more consistent performance over time.
- Reinforced 60° Point Angle & 3xD Flute Length: Ensures aggressive yet stable penetration, excellent centering, and efficient chip evacuation in deep-hole drilling operations.
- Robust Core & Precision Straight Shank: The thicker core diameter in this size range dramatically increases torsional strength, reducing the risk of breakage under high loads.
- Optimized for 3-4mm Range: Specifically engineered for stability in this critical diameter range, preventing deflection and ensuring hole accuracy.

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.
Yes, we support machine shops, distributors, and global buyers with tiered wholesale pricing and competitive volume discounts. We also provide OEM custom manufacturing solutions for tool holders and carbide inserts based on your technical drawings. Contact our team to request a quick B2B quotation.
We provide secure worldwide express shipping (via DHL, FedEx, and UPS) with specialized, vibration-proof industrial packaging to ensure tools arrive in perfect condition. In-stock items are dispatched within 24-48 hours, while custom or bulk orders typically have a stable lead time of 15-25 days.
All our cutting tools and tool holders are manufactured strictly in accordance with ISO 9001 and international industrial standards. Every batch undergoes 100% rigorous quality control testing using high-precision optical measuring equipment to ensure reliable tool life and stable performance in continuous mass production.
