Tungaloy TCMT110204-PS T9115 Turning Insert
High-Performance CVD Coated Carbide | T9115 Steel Grade | 0.4mm Precision Radius
What is the best carbide grade for high-speed continuous steel finishing?
The Tungaloy TCMT110204-PS T9115 is a premium triangular indexable turning insert engineered for high-precision finishing operations on ISO P (Steel) materials. Featuring the advanced T9115 CVD coating, this insert provides exceptional wear resistance and thermal stability during high-speed machining. The 0.4mm corner radius (04) and the -PS (Power Sharp) chipbreaker are optimized for light depths of cut, ensuring superior chip evacuation and a high-gloss surface finish. 100% Made in Japan, it is the ideal solution for CNC shops prioritizing dimensional accuracy and reduced downtime.
T9115 CVD Grade
A specialized CVD coated grade with a thick Alumina (Al2O3) layer. It offers extreme crater wear resistance at high temperatures, allowing for cutting speeds far exceeding standard carbide.
-PS Sharp Breaker
The "Power Sharp" geometry features a highly positive rake. It minimizes cutting force and prevents built-up edge (BUE), which is crucial for finishing low-carbon steels.
0.4mm Radius Precision
The 0.4mm corner radius (04) offers the perfect balance between edge strength and surface smoothness, allowing for precise corner details while maintaining tool durability.

Real Feedback from Global Machinists
⭐⭐⭐⭐⭐ "Consistent Finishing" - James D., USA
"The 0.4 radius is my go-to for finishing steel pins. T9115 grade holds the tolerance perfectly throughout the batch."
⭐⭐⭐⭐⭐ "Top Grade" - Karl R., Germany
"Excellent wear resistance. We use these in our high-speed boring bars and the surface finish is mirror-like."
⭐⭐⭐⭐ "Very Stable" - Lin S., Singapore
"Consistent chip breaking and predictable tool life. Genuine Tungaloy product with fast shipping."
⭐⭐⭐⭐⭐ "Industrial Reliable" - Marco V., Italy
"The -PS breaker handles light cuts beautifully. No stringy chips and the Ra is better than advertised."
⭐⭐⭐⭐⭐ "Five Stars" - Arjun P., India
"Beyond OYYU is a reliable supplier. These T9115 inserts significantly reduced our tool cost per part."
8. FAQ - Professional Support
Q: Is T9115 better than T9215 for finishing?
A: T9115 is a classic, highly stable grade. While T9215 is newer, many shops prefer T9115 for its predictable performance in precise finishing passes.
Q: Does this fit my existing S12M-STFCR11 boring bar?
A: Yes, it is fully compatible with any STFCR/L or STUCR/L holder using TCMT 1102 size inserts.
Industrial Tip: CVD vs. PVD for Steel
Select **T9115 CVD Carbide** when your priority is tool life during long, continuous high-speed finishing runs. The thermal protection of Alumina coating allows for higher productivity without losing edge integrity. For precision steel turning, **Tungaloy Japan** is the professional choice.
