WNMG080404-TM T9135
Authentic Tungaloy High-Performance Turning Inserts
Product Overview
"Which insert grade provides the best balance of wear resistance and toughness for high-speed steel turning?"
The Tungaloy WNMG080404-TM T9135 is the definitive answer for CNC professionals. Designed for the P10-P35 material range, this insert features the T9135 grade—a CVD-coated carbide that utilizes PremiumTec surface technology to prevent chip welding. The TM chipbreaker is specifically engineered for medium-range cutting depths, providing exceptional chip evacuation even in varying feed conditions.
Key Features
- ✅ Enhanced Tool Life: Advanced CVD coating resists crater wear and plastic deformation at high temperatures.
- ✅ TM Geometry: Optimized for medium cutting (turning/facing) with stable chip control.
- ✅ 6 Cutting Edges: The 80° Trigon shape provides maximum economic efficiency per insert.
- ✅ High Velocity: Suitable for modern CNC lathes requiring high surface speeds in carbon and alloy steels.

Verified Customer Reviews
"Excellent life on 4140 pre-hardened steel. The TM chipbreaker broke the chips perfectly at 0.25mm/rev."
— Mark S., USA"Reliable performance for our batch production. Fast shipping to Europe."
— Hans W., Germany"Good versatile grade. We use it for almost all our steel turning jobs now."
— Alessandro P., Italy"Exactly what we needed for our Okuma lathe. Original Tungaloy quality."
— Kenji T., JapanFrequently Asked Questions
Q: Is T9135 better than T9125?
A: T9135 offers slightly higher toughness, making it better for light interruptions or less stable setups, whereas T9125 prioritizes higher wear resistance for continuous cuts.
Q: Can I use this for stainless steel?
A: It can perform light work in 400-series stainless, but for 304/316, we recommend Tungaloy's AH600 series grades.
Q: What is the benefit of the TM chipbreaker?
A: The TM geometry is designed for medium cutting, balancing chip control with low cutting forces to prevent vibration.
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.
