Tungaloy TCMT110202-PS T9115 Turning Insert
High-Performance CVD Coated Carbide | T9115 Steel Grade | 0.2mm Precision Radius
What is the best carbide grade for high-speed continuous steel finishing?
The Tungaloy TCMT110202-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 0.2mm corner radius (02) 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.
0.2mm Radius Precision
The ultra-small radius allows for intricate profile turning and fine boring with minimal vibration, making it perfect for small-diameter parts with strict Ra requirements.

Real Feedback from Global Machinists
⭐⭐⭐⭐⭐ "Perfect for Finish Boring" - James D., USA
"The 0.2 radius is exactly what we needed for our precision bores. Very low vibration and the T9115 grade lasts much longer in high-speed runs than my previous coated carbide."
⭐⭐⭐⭐⭐ "Stable and Precise" - Karl R., Germany
"Tungaloy Japan never disappoints. Consistent results part after part. Great chip control with the -PS breaker even at very light feeds."
⭐⭐⭐⭐ "Great Life at High Vc" - Lin S., Singapore
"Run it fast and it shines. Excellent service from the Beyond team, products are definitely genuine factory stock."
⭐⭐⭐⭐⭐ "Mirror Finish" - Marco V., Italy
"Superior surface Ra compared to standard PVD inserts. T9115 is my go-to for finishing carbon steel components."
⭐⭐⭐⭐⭐ "Reliable B2B Partner" - Arjun P., India
"The technical specifications provided were spot on. These inserts increased our throughput on the CNC lathe by 20%."
8. FAQ - Professional Support
Q: Is T9115 suitable for Stainless Steel?
A: T9115 is optimized for ISO P (Steel). For Stainless (ISO M), we recommend PVD grades like AH725 for better work-hardening resistance.
Q: Can I use this for interrupted cuts?
A: The 0.2mm radius is delicate. For heavy interrupted cuts, we suggest using a 0.4mm or 0.8mm radius to increase edge toughness.
Q: Does it fit my existing STUCR11 bar?
A: Yes, it fits any holder designed for the TCMT 1102 / TCMT 21.5 standard pockets.
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.
