BEYOND HRC60 3D Coated Carbide Micro Drill Bits: Precision for Demanding Materials
Engineered for excellence, BEYOND's 3D coated carbide micro drill bits (1.0-1.95mm) are designed to tackle the most challenging materials with exceptional precision and durability. The HRC60 hardness and innovative 3x diameter flute length make these bits ideal for deep, precise holes in hardened steels, stainless steel, and alloys on your CNC machining centers and engraving machines.
Key Features & Benefits:
- ✅ Ultra-Hard HRC60 Tungsten Carbide: Withstands extreme pressure and retains a sharp cutting edge far longer than HSS drills.
- ✅ Advanced 3D Coating (Bronze Color): Reduces friction, improves heat dissipation, and significantly extends tool life.
- ✅ 3x Diameter (3xD) Flute Length: Perfect for deeper hole drilling and precision milling operations in confined spaces.
- ✅ Precision Ground Straight Shank: Ensures maximum grip and minimal run-out for superior accuracy in collets and chucks.
- ✅ Micro Diameter Range (1.0mm - 1.95mm): Designed for high-precision applications in electronics, mold making, and fine mechanics.
Ideal Applications & Materials:
- Primary Materials: Hardened Steel (HRC~65), Pre-hardened Steel (P20, H13), Tool & Die Steel, Stainless Steel (SUS303, 304, 416), Alloy Steel (SCM, SCr, SNCM).
- Perfect for Use On: CNC Machining Centers, Precision Engraving Machines, Jewelry Making Tools, PCB Drilling, and Mold Manufacturing.
Technical Specifications & Cutting Data Reference:
For hardened steel (HRC~45-65), stainless steel, and alloy steel.

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.
