CNMG190612-ER YBM151 ZCC.CT Carbide Turning Inserts
Product Overview
"Which carbide insert grade is best for high-speed finishing and semi-finishing of austenitic stainless steel while maintaining edge sharpness?"
The CNMG190612-ER YBM151 is specifically engineered for precision in challenging environments. The YBM151 grade utilizes a specialized CVD coating (TiCN + Al₂O₃ + TiN) over a tough substrate, offering exceptional resistance to thermal cracking and plastic deformation. Combined with the ER chipbreaker—a geometry designed for stable chip control in continuous to light interrupted cuts—this insert ensures a superior surface finish on M-class materials.

— Kenji S., JapanFrequently Asked Questions
Is YBM151 suitable for interrupted cutting?
YBM151 is a high-hardness grade optimized for finishing. For heavy interrupted cutting, we recommend the tougher YBM251 or YBM253 grades.
What is the benefit of the ER chipbreaker?
The ER geometry features a strengthened cutting edge specifically for stainless steel, preventing notched wear and edge chipping.
What materials fall under the M-Class category?
M-Class refers to Stainless Steel, including 200, 300, and 400 series (e.g., 304, 316, 420).
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.
