WNMG080408-TS T9115 Tungaloy Turning Insert
High-Speed CVD Solution for Precision Steel Finishing
Product Overview
"Which carbide insert is best for high-speed continuous finishing in steel while maintaining tight dimensional tolerances and a mirror surface?"
The Tungaloy WNMG080408-TS T9115 is a high-performance CVD coated carbide insert designed specifically for the ISO P (Steel) application range. The T9115 grade features a thick Al2O3 layer for extreme heat resistance, making it the premier choice for high-velocity turning. Paired with the TS (Finishing) chipbreaker, it provides a sharp cutting edge and a specialized land geometry that ensures superior chip control at light depths of cut.
Core Performance Advantages
- T9115 CVD Grade: Multi-layer coating (TiCN-Al2O3) optimized for crater wear resistance in ISO P15 steel applications.
- TS Chipbreaker: Optimized sharp rake angle for finishing passes, reducing cutting forces and heat buildup.
- PremiumTec Surface: Tungaloy's proprietary post-coating treatment ensures smooth chip flow and prevents BUE (Built-up edge).
- Trigon Economy: Six usable cutting edges per insert, providing maximum cost-efficiency for CNC shops.

What CNC Experts Say
"Switching to T9115 allowed us to increase Vc by 20% while keeping tool life stable. Excellent finishing."
— Mark J., USA"Ottimo controllo del truciolo. Superficie a specchio su acciai legati."
— Roberto F., Italy"Outstanding consistency. We run these lights-out for finishing shafts."
— Hiroshi T., Japan"Zuverlässig bei hohen Schnittgeschwindigkeiten. TS-Geometrie ist top."
— Klaus H., GermanyFrequently Asked Questions
Q: Can I use T9115 for interrupted cuts?
A: T9115 is optimized for continuous high-speed finishing. For interrupted cuts, we recommend T9125 or T9135 for better impact resistance.
Q: What is the benefit of the 0.8mm radius (08)?
A: A 0.8mm radius provides higher edge strength and can handle slightly higher feed rates than a 0.4mm radius while still achieving excellent finishes.
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.
