Tungaloy TCMT110204-PS AH725 Turning Insert
Precision Finishing | High-Performance AH725 PVD Carbide | 0.4mm Radius
What is the most effective insert for precision finishing on steel and stainless?
The Tungaloy TCMT110204-PS AH725 is a high-precision triangular indexable insert designed for the rigorous demands of finishing operations. Featuring the state-of-the-art AH725 PVD coated carbide grade, this insert excels in maintaining edge sharpness and preventing built-up edge (BUE) in ISO P (Steel) and ISO M (Stainless Steel) materials. The -PS chipbreaker geometry is specifically engineered for light depths of cut, ensuring excellent chip control and a superior surface finish. 100% Made in Japan, it is the professional choice for CNC machining centers prioritizing accuracy and tool longevity.
AH725 PVD Excellence
A specialized PVD coating with high adhesion strength. It provides a smooth surface that reduces friction and heat, significantly extending tool life in precision turning.
-PS Precision Breaker
The 'PS' (Power Sharp) breaker is Tungaloy's answer to difficult chip control during finishing. It curls and breaks chips effectively at low feed rates.
Tight Tolerance Control
Manufactured with M-class tolerances, ensuring high repeatability and dimensional accuracy for critical component manufacturing.

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 - 1.5 mm
*Machinist Advice: For stainless steel, stay toward the lower end of the Vc range and use ample coolant to maximize the effectiveness of the PVD coating.*

8. FAQ - Machining Support
Q: Why use PVD AH725 instead of CVD grades?
A: PVD coatings allow for much sharper cutting edges, which is essential for precision finishing and preventing built-up edges in sticky materials like stainless steel.
Q: Is this insert suitable for interrupted cuts?
A: While it is optimized for finishing (continuous cutting), the AH725 grade has high adhesion strength which can handle light interruptions better than standard finishing grades.
Q: Will this fit my TCMT 1102 holder from another brand?
A: Yes, as long as your holder is designed for the ISO TCMT 1102 (1/4" Inscribed Circle) specification, it will be perfectly compatible.
Expert Comparison: PVD vs. CVD Finishing
The **PVD AH725** grade is the professional's choice for precision finishing where surface Ra and edge sharpness are critical. For high-speed, heavy-duty production in carbon steel, a **CVD grade** like T9125 would be more efficient. For precision and stainless steel, **Tungaloy Japan** is the industrial gold standard.
