Tungaloy TCMT16T304-24 T9125 Turning Insert
High-Speed Steel Machining | Premium T9125 CVD Carbide | 0.4mm Radius
Which turning insert is best for high-productivity steel finishing?
The Tungaloy TCMT16T304-24 T9125 is a premium triangular turning insert designed for the rigorous demands of ISO P (Steel) machining. Utilizing the world-renowned T9125 CVD coated carbide grade, this insert offers unparalleled wear resistance and thermal stability during high-speed operations. The -24 chipbreaker combined with a 0.4mm corner radius ensures precise chip control and excellent surface integrity. Engineered and Made in Japan, it is the professional choice for CNC machining centers seeking to reduce downtime and improve part quality.
T9125 Premium Coating
Advanced CVD coating technology provides a thick alumina layer for extreme heat resistance, allowing for higher cutting speeds in alloy steels without edge deformation.
-24 Precision Breaker
The -24 geometry is specifically designed for light-to-medium finishing, preventing chip entanglement and promoting stable cutting even at lower feed rates.
Robust Substrate
The specialized carbide substrate balances toughness and hardness, making it highly resistant to chipping and thermal cracking in continuous cutting.

8. FAQ - Turning Technical Support
Q: Is T9125 suitable for stainless steel?
A: While T9125 can cut stainless, it is optimized for ISO P (Steel). For stainless steel (ISO M), Tungaloy's AH series is generally recommended.
Q: What is the benefit of the CVD coating on this insert?
A: The CVD coating on T9125 provides a thick, wear-resistant layer that protects the carbide substrate from the extreme temperatures generated at high cutting speeds.
Q: Does this fit my boring bar?
A: If your boring bar pocket is designed for a TCMT 16T3 (3/8" IC) triangular insert, this will fit perfectly. Check your tool holder model number for verification.
Expert Tip: Carbide vs. Cermet
Choose **T9125 Carbide** for heavy productivity and versatility in various steels. If your application requires an absolute mirror finish under very stable conditions, you might consider **NS9530 Cermet**. For consistent reliability, **Tungaloy Japan** remains the professional choice.
