The Universal Choice for Steel Productivity
UE6020 Grade (The Fracture Barrier): The UE6020 is a high-toughness CVD-coated grade specialized for P-Class (Steel) turning. It features a specialized multi-layer coating that provides a high degree of resistance to flank wear and cratering. Its greatest strength lies in its ability to prevent edge fracture during interrupted cuts or when machining parts with a rough, uneven surface.
MH Chipbreaker (Universal Medium Cutting): The MH geometry is the first choice for medium-range cutting. It balances a sharp cutting edge with a reinforced land, allowing for smooth chip breaking across a broad spectrum of feed rates. This eliminates the need for tool changes between semi-roughing and semi-finishing passes, significantly reducing cycle times.
0.8mm (1/32") Corner Radius: The 08 radius is the most popular size for general-purpose turning. It provides excellent edge strength while maintaining low enough cutting forces to be used on a wide variety of lathe sizes and power ratings.

UE6020 (The Impact Fighter): Choose this grade for jobs with unstable parts, interruptions, or older machines. It is the toughest "all-rounder" for steel.
MC6025 (The High-Speed All-Rounder): Switch to MC6025 for high-speed continuous cutting in stable environments to maximize tool life and throughput.

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.
