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).
