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
When choosing CNC cutting tools, check the full model code, dimensions, grade and selected variant before ordering. Do not rely on the product image alone.
For carbide inserts, tool holders, drills and end mills, compare the mounting dimensions, connection type and manufacturer's specifications with your holder or machine. If you are unsure, share your existing part number and machining application with us before ordering.
Check the product listing for the selling unit, pack quantity and included components. If it is unclear whether the price is per piece or per pack, or whether a tool body and inserts are sold separately, contact us before purchasing.
Select cutting speed, feed rate and depth of cut using the relevant manufacturer's recommendations for your tool model, workpiece material, machine conditions and coolant method. The same settings are not suitable for every product or application.
