Tungaloy TCMT16T308-PS AH725 Turning Insert
High-Performance Steel Machining | Premium AH725 PVD Carbide | 0.8mm Radius
What is the most durable PVD insert for finishing steel parts?
The Tungaloy TCMT16T308-PS AH725 is a high-performance triangular turning insert designed for precision finishing and semi-finishing of ISO P (Steel) and ISO M (Stainless Steel). Built with the legendary AH725 PVD multi-layered coating, this insert provides an exceptional balance of edge sharpness and thermal stability. The -PS chipbreaker is specifically engineered for light cutting depths, while the 0.8mm corner radius (08) offers superior edge strength compared to smaller radii. 100% Made in Japan, it ensures high reliability for professional CNC manufacturing.
AH725 Multi-Layer PVD
A premium PVD coating that maintains edge sharpness while providing a barrier against built-up edge (BUE). Perfect for finishing sticky materials like stainless and low-carbon steels.
-PS "Power Sharp" Breaker
Designed for high-precision finishing. The -PS geometry breaks chips effectively even at extremely low feed rates, ensuring a clean workpiece surface without scratches.
0.8mm Edge Durability
The 0.8mm radius (08) allows for higher feed rates and better heat dissipation, making it more robust for varied steel applications than the 0.4mm versions.

Recommended Cutting Parameters (AH725)
-
Cutting Speed (Vc): 80 - 180 m/min
-
Feed Rate (f): 0.08 - 0.25 mm/rev
-
Depth of Cut (ap): 0.2 - 2.5 mm
*Optimization Tip: For higher surface quality, increase the cutting speed toward 150m/min and maintain a steady feed rate to engage the -PS chipbreaker effectively.*

8. FAQ - Machining Solutions
Q: Is AH725 good for stainless steel?
A: Yes, AH725 is a multi-layered PVD grade that performs exceptionally well in ISO M stainless steels due to its sharp edge and high heat resistance.
Q: How does the -PS chipbreaker compare to -PM?
A: The -PS is designed specifically for "Power Sharp" finishing at light depths of cut, whereas -PM is a more general-purpose medium cutting breaker.
Q: Will this fit my 3/8" IC holder?
A: Yes, the TCMT 16T3 series is the standard metric equivalent to the 3/8" Inscribed Circle size used in standard ISO holders.
Expert Comparison: PVD vs. CVD Coatings
Select **PVD AH725** for precision finishing and sharp edge requirements to prevent built-up edge. If you are doing heavy-duty roughing at high speeds, a **CVD grade** like T9225 would be more efficient. For precision work, **Tungaloy Japan** is the professional choice.
