WNMG080412-TM T9135 Turning Insert
Premium Tungaloy Solution for High-Efficiency Steel Machining
Product Overview
"Which carbide insert grade provides the best balance of wear resistance and edge strength for medium-heavy steel turning?"
The Tungaloy WNMG080412-TM T9135 is engineered to solve the challenges of high-speed steel turning. Utilizing the T9135 CVD grade, this insert features a thick Al2O3 layer that offers exceptional heat resistance. The TM chipbreaker (Medium-cut) and the 1.2mm (047") nose radius provide a robust cutting edge that excels in medium turning applications where surface finish and edge stability are critical.
Core Performance Advantages
- T9135 PremiumTec Coating: A dual-layer CVD coating (TiCN + Al2O3) that drastically reduces crater wear during high-velocity cuts.
- Robust 1.2mm Radius: Provides high edge strength and enables higher feed rates while maintaining structural integrity.
- Stable TM Geometry: Designed specifically for chip control in the medium cutting range (P15-P35), ensuring smooth evacuation.
- Double-Sided Economy: Trigon shape provides 6 usable cutting edges, lowering your cost-per-part significantly.

Expert Choice: User Feedback
"The 1.2mm radius on the T9135 grade is a beast for forged steels. Excellent tool life."
— Mike D., USA"Qualität ist hervorragend. T9135 ist sehr stabil bei unterbrochenem Schnitt."
— Stefan W., Germany"Perfetto per acciai legati. La geometria TM rompe bene il truciolo."
— Marco V., Italy"Consistent performance. We use these for our automotive production line in Nagoya."
— Takashi K., JapanCommon Technical Questions
Q: When should I choose WNMG080412 over WNMG080408?
A: Use the 1.2mm radius (080412) for higher edge security and when your machining parameters allow for a larger radius to increase feed rates.
Q: Can I use T9135 for stainless steel?
A: T9135 is optimized for Steel (ISO P). While it can handle some 400-series stainless, we recommend the AH600 series for Austenitic Stainless Steel (ISO M).
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.
