Material Grade: UE6110 (The Steel Master)
The UE6110 grade is a CVD coated carbide designed for a broad range of steel turning. Its multi-layer coating provides high resistance against flank wear and cratering. It is optimized for P-class materials, offering incredible tool life in stable environments where high cutting speeds are required.
Geometry & Chipbreaker
The WCMT geometry is a positive rake design that lowers cutting resistance. This helps in maintaining part accuracy and achieving a superior surface finish. It is excellent for clearing chips efficiently during high-precision CNC machining of standard steels.
Recommended Cutting Parameters
Optimized for P10-P25 steel machining:
- Cutting Speed (Vc): 180 - 320 m/min (590 - 1050 SFM)
- Feed Rate (f): 0.08 - 0.20 mm/rev (0.003 - 0.008 ipr)
- Depth of Cut (ap): 0.3 - 2.0 mm
*Note: Ensure rigid clamping to take full advantage of the UE6110's high-speed capabilities.

Questions & Answers
Q: Is WCMT020104 UE6110 suitable for stainless steel?
A: While it can cut stainless, UE6110 is specifically optimized for Steel (P-class). For better results in stainless steel, we recommend the US735 or MC7025 grades.
Q: What kind of chip control should I expect?
A: The WCMT geometry provides excellent chip breaking at medium-to-light depths of cut, ensuring safety for both the machine and the operator.
Q: Does this fit my small boring bar?
A: Yes, this 02-size insert is commonly used in small diameter internal boring bars (e.g., 6mm or 8mm shanks).
Material Comparison Tip: UE6110 vs. UE6020
Choose UE6110 when your primary goal is high-speed wear resistance in stable steel turning. If your application involves heavy interruptions or unstable setups, consider UE6020 for its higher fracture toughness.
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.
