Tungaloy WNMG080408-TM T9135 Carbide Turning Insert
Industrial Grade CVD Coated Trigon Inserts for Steel Excellence
Product Overview
"Which insert is best for high-speed medium cutting in steel with interrupted cuts?"
The Tungaloy WNMG080408-TM T9135 is the industry's answer to efficient steel turning. This insert features the T9135 grade, a specialized CVD-coated carbide that balances extreme wear resistance with the toughness required to handle slight interruptions. The TM (Medium-cut) chipbreaker is designed with a unique geometry that ensures smooth chip evacuation across a wide range of feed rates, preventing chip bird-nesting and protecting your workpiece finish.

— Kenji H., Japan"Great customer support. They helped us dial in the Vc for our new Okuma."
— Sarah B., UKFrequently Asked Questions
Q: Is T9135 suitable for stainless steel?
A: T9135 is optimized for Steel (P). For Stainless Steel (M), we recommend Tungaloy AH630 or AH645 grades.
Q: What is the benefit of the 0.8mm nose radius?
A: The 0.8mm (432) radius provides higher edge strength and better surface finish at higher feed rates compared to a 0.4mm radius.
Q: Can I use this for finishing?
A: The TM breaker is for medium cutting. For fine finishing, consider the TSF or TFP chipbreaker geometries.
Machining Pro Tip: For maximum tool life, ensure a stable tool overhang and use high-pressure coolant to enhance chip evacuation when using the TM geometry in deep cuts.
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.
