Tungaloy TCMT16T304-PS AH725 Turning Insert
Professional Steel Machining | Advanced AH725 PVD Grade | 0.4mm Radius
What is the best PVD grade for high-precision finishing on steel alloys?
The Tungaloy TCMT16T304-PS AH725 is a robust triangular indexable insert designed for finishing and semi-finishing of ISO P (Steel) and ISO M (Stainless Steel). Utilizing the industry-leading AH725 PVD multi-layered coating, this insert provides incredible toughness and thermal stability. The -PS chipbreaker is Tungaloy's specialized geometry for finishing operations, ensuring excellent chip evacuation even at very light depths of cut. 100% Made in Japan, it delivers the precision required for high-end CNC manufacturing and boring operations.
AH725 Multi-Layer PVD
Designed for general-purpose turning of steels. The multi-layered PVD coating ensures high resistance to built-up edge (BUE) and offers long, predictable tool life.
-PS Finishing Breaker
The PS (Power Sharp) geometry features a sharp cutting edge that reduces cutting resistance and allows for superior chip control at low feeds.
High Thermal Stability
Engineered to withstand the high heat generated during finishing passes, preventing corner wear and maintaining surface Ra quality across large batches.

Recommended Cutting Parameters (AH725)
-
Cutting Speed (Vc): 80 - 180 m/min
-
Feed Rate (f): 0.05 - 0.20 mm/rev
-
Depth of Cut (ap): 0.2 - 2.5 mm
*Optimization Tip: For low-carbon steel, use a higher cutting speed (160m/min) to achieve the best surface finish and reduce tool pressure.*

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.
