BEYOND YWMT16T304-ZM T9125 Indexable Carbide Insert
High-precision 35-degree rhombic profiling insert with positive 7-degree relief, engineered for exceptional surface finishes in steel turning.
Product Overview
"Which carbide insert is best for minimizing vibration during deep profiling and internal boring of steel parts?"
The BEYOND YWMT16T304-ZM is the definitive choice for precision CNC profiling. Its unique 35° parallelogram shape provides the necessary clearance for intricate contours, while the ZM chipbreaker ensures stable chip control during light to medium cutting. Powered by the T9125 CVD grade, featuring thick TiCN and Al2O3 coating layers, this insert delivers outstanding wear resistance and tool life in high-speed steel turning (ISO P20-P30).

Verified User Reviews
"Excellent chip control on alloyed steel profiling. The T9125 grade provides a very stable tool life in high-speed conditions."
"Used these on our Swiss lathe for complex kontouring. The surface finish was Ra 0.8 without a problem. Good clearance."
"Stable performance. Very reliable for lights-out machining."
FAQ
💡 Tech Tip: Material Selection
Always use high-pressure through-coolant when profiling to ensure the ZM chipbreaker can effectively eject curls from deep grooves. For continuous high-speed finishing, maintain Vc at the upper limit (300+ m/min) to fully activate the Al2O3 coating layer.
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.
