TCMT 110308 AH725 Tungaloy turning insert — PVD-coated carbide, 60° triangular

The TCMT110308 AH725 Tungaloy insert is an ISO-standard triangular turning insert designed for external and internal turning, offering a universal, crack-resistant grade for mixed steel and stainless steels applications.

• PVD-coated carbide grade AH725
• Universal, crack-resistant for steel and stainless steels
• 60° triangular insert with 0.8 mm corner radius
• Cylindrical hole with single-side countersink

Stable performance across mixed materials

The combination of the AH725 grade and a PVD surface layer provides a balance between toughness and wear resistance that supports processing of both steel and stainless steels. As a universal, outburst-resistant grade, AH725 reduces the need for frequent insert changes when batches vary, which improves machine uptime. The PVD coating (Physical Vapour Deposition) enhances resistance to adhesion and thermal wear; this results in more predictable tool life and steadier cutting forces during interrupted cuts or variable feeds.

Geometry engineered for consistent surface quality

A 60° triangular cutting shape paired with a 0.8 mm corner radius produces a controlled cutting edge that maintains stability under radial and axial loads. The modest corner radius offers a compromise between edge strength and the ability to achieve a fine surface finish; larger radii increase edge support, while smaller radii favour sharpness. The 7° clearance angle and a plate thickness of 3.18 mm contribute to reduced rubbing and improved heat evacuation, translating into repeatable part tolerances and a reliable finish in serial production.

ISO compatibility and secure mounting for fast changeover

As an ISO-standard turning insert, compatibility with holders is determined by form, clearance angle, tolerance class, fastening type, size and thickness. The cylindrical hole with a single-sided countersink (40°–60°) ensures positive seating and straightforward indexing when used with the matching clamp set and screws. The system build—insert, matched external holder or boring bar, support shim and clamp—minimises set-up time and supports faster, safer tool changes on the shop floor.

Process security and predictable tool life

The integrated single-sided chipbreaker and the AH725 substrate are optimised for stable chip control and consistent edge behaviour, particularly useful for smaller tools or setups with high demands on process security. Selecting the correct chipbreaker and insert grade according to workpiece material and machining strategy will reduce scrap and enhance productivity. The robust carbide substrate and PVD finish combine to produce a dependable performance profile that supports controlled wear progression rather than sudden failure.

FAQ

What materials can this insert machine effectively?
The TCMT110308 AH725 Tungaloy insert is intended for machining steel and stainless steels; the universal AH725 grade provides crack resistance across varying components.

How does the PVD coating benefit performance?
The PVD coating on the AH725 substrate reduces adhesion and thermal wear, improving edge stability and producing more predictable tool life for the TCMT110308 insert.

Which holders are compatible with this insert?
Compatibility depends on holder form, clearance angle, tolerance class, fastening method, size and thickness; use holders designed for ISO triangular inserts to secure the TCMT110308 correctly.

What is the effect of the 0.8 mm corner radius?
A 0.8 mm corner radius increases edge strength and supports consistent surface finish while balancing cutting forces and allowing controlled material removal in turning operations.

Is the insert suitable for interrupted cuts or small tools?
Yes; the AH725 grade is described as crack-resistant and suitable for smaller tools and applications with high demands on process security, making it well suited to interrupted cuts.
