Tungaloy WNMG060412E-TM T9125 Turning Insert
Superior Toughness for High-Speed Steel Turning & Medium Cutting
Product Overview
"Which insert provides the best edge strength for medium turning of alloy steel while maintaining a long tool life at high speeds?"
The Tungaloy WNMG060412E-TM T9125 is the industry benchmark for general steel turning (ISO P). Utilizing the T9125 CVD grade, it features PremiumTec surface technology which significantly reduces friction and crater wear. The TM (Medium-cut) chipbreaker is paired with a robust 1.2mm nose radius, making it the ideal choice for applications requiring high edge security, increased feed rates, and excellent chip evacuation in carbon and alloy steels.
Core Performance Advantages
- T9125 CVD Grade: Multi-layered coating (TiCN-Al2O3) optimizes wear resistance and thermal protection at high speeds.
- Robust 1.2mm Radius: Provides exceptional edge strength, allowing for higher feed rates and improved durability in rougher environments.
- TM Geometry: Optimized chipbreaker land provides a stable cutting edge that prevents crater wear during medium turning.
- Six Cutting Edges: The Trigon (W) shape offers the economy of multiple edges with the strength of a square insert.

Why Machinists Trust T9125
"The 1.2mm radius is a beast for our rougher alloy steel parts. T9125 holds the edge twice as long as our previous brand."
— Mike D., USA"Ottima resistenza. Rompitruciolo TM perfetto per acciai da costruzione."
— Alessandro M., Italy"Consistent performance in high-speed production. My first choice for 1045 steel."
— Hiroshi S., Japan"Top Standzeit bei Stahl. Sehr zuverlässig bei mittleren Schnitttiefen."
— Klaus K., GermanyFrequently Asked Questions
Q: Is the 1.2mm radius too large for finishing?
A: This radius is optimized for medium-to-heavy cutting. While it can finish, it requires a higher feed rate to avoid vibration and may not be suitable for very fine precision finishes compared to a 0.4mm radius.
Q: What is 'E' in the model code?
A: The 'E' refers to the cutting edge treatment (honing/rounding). This increases edge security and prevents premature chipping under load.
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.
