Tungaloy TCMT110208-PS AH725 Turning Insert
High-Precision Steel Machining | Premium AH725 PVD Carbide | 0.8mm Radius
What is the most durable PVD insert for finishing steel parts?
The Tungaloy TCMT110208-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 coated carbide grade, 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 PVD Coating
Features high-adhesion PVD technology that prevents chipping and built-up edge (BUE). It is the ideal choice for small-diameter parts and finishing where surface quality is critical.
-PS Precision Geometry
The 'Power Sharp' (-PS) breaker provides excellent chip control at low feeds. It curls the chips tightly to avoid workpiece scratching and machine downtime.
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): 0.05 - 0.25 mm/rev
-
Depth of Cut (ap): 0.2 - 2.0 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.*
4. Product Applications
- Precision turning of alloy steels and 300-series stainless.
- Machining of small shafts and hydraulic components.
- Boring operations where vibration damping is necessary.
- Final finishing of heat-treated parts where edge toughness is required.
5. Tool Compatibility
Compatible with standard Tungaloy / ISO boring bars and turning holders designed for TCMT 1102 size inserts (1/4" Inscribed Circle). Fits standard S-STFCR/L shanks.

Professional Machinist Feedback
⭐⭐⭐⭐⭐ "Great for Alloy Steels" - Heinrich L., Germany
"The AH725 grade handles tough alloys beautifully. The 0.8mm radius is strong and doesn't chip during light interruptions."
⭐⭐⭐⭐⭐ "Excellent Surface Finish" - Robert T., USA
"Even with the 0.8mm radius, the finish is fantastic. The -PS breaker keeps the chips short and away from the tool."
⭐⭐⭐⭐ "Very Stable" - Takeshi K., Japan
"Tungaloy quality as expected. Consistent dimensions across the whole box. Very reliable for long production runs."
⭐⭐⭐⭐⭐ "B2B Choice" - Marcus W., UK
"Ordered these for a large contract. CNCHome-Beyond provided original stock quickly. Performance is superior to alternatives."
⭐⭐⭐⭐⭐ "Perfect for Boring" - Tan Wei L., Singapore
"Using these in our 12mm boring bars. Stable cutting and excellent chip evacuation in blind holes."
8. FAQ - Technical Assistance
Q: Is AH725 better than AH120 for steel?
A: AH725 is a multi-layered PVD grade specifically optimized for general-purpose turning with high edge sharpness, making it better for finishing and small parts than AH120.
Q: Can I use this for deep boring?
A: Yes. The triangular TCMT shape combined with the sharp -PS breaker reduces cutting force, which helps minimize vibration in deep boring applications.
Q: Does it fit my standard 1/4" IC holder?
A: Yes, TCMT 1102 designates an 11mm edge length with a 6.35mm (1/4") Inscribed Circle, following ISO standard dimensions.
Industrial Tip: When to choose PVD AH725
Select **PVD AH725** for precision finishing where sharp edges are required to prevent work hardening. For heavy-duty, high-speed production of carbon steels, a **CVD grade** like T9125 might be preferred. For consistency and fine detail, **Tungaloy Japan** is the professional choice.
