TCMT 090204 AH725 indexable turning insert – triangular 60° form, PVD-coated carbide, Tungaloy

TCMT090204 AH725 is an ISO-format indexable turning insert for general turning applications, offering a fracture-resistant grade for mixed-material production with stable chip control.

*Universal AH725 grade, fracture-resistant *PVD-coated carbide for improved tool life *Triangular 60° ISO geometry for versatility *Single-sided chipbreaker with 0.4 mm radius

Reliable process security for consistent turning results

The PVD-coated carbide substrate and the AH725 grade combine to provide stable cutting behaviour in variable production environments. This insert is designed to reduce unexpected edge breakouts and to maintain dimensional consistency, which lowers scrap rates and increases first-pass yield. The ISO triangular form with a 60° included angle offers multiple cutting edges per insert and straightforward indexing, supporting faster tool changes and predictable setup times. By focusing on controlled chip formation and a robust cutting edge, the component helps secure repeatable cycle times and reduces downtime related to insert failure.

Efficient versatility across steels and stainless steels

Engineered as a universal solution, the grade suits machining of steel and stainless steels, making it a practical choice where material mixes occur. The single-sided chipbreaker is optimised for general-purpose turning and assists in producing manageable chips under a range of feeds and depths of cut, simplifying chip evacuation and reducing interference with workpiece finish. The combination of material and surface treatment helps preserve edge integrity when small tools or demanding process conditions are required, enabling reliable results without frequent grade changes.

Simple integration, clear ergonomic benefits at the machine

Compatibility is governed by the ISO designation, seating form and clamping interface rather than brand-specific features, so the insert fits holders and boring bars designed for ISO TCMT inserts when size, thickness and hole style match. The 0.4 mm corner radius and 2.38 mm thickness give a balance between edge strength and accessibility in turning profiles, while the cylindrical hole with single-side countersink (40°–60°) supports secure fastening and consistent clamping torque. These characteristics aid tool life predictability and lower the frequency of regrinding or replacement in routine production.

Practical economic effects for the workshop

Choosing a universal, robust insert reduces the need for multiple special grades, which simplifies inventory and purchasing. The combination of a durable substrate and PVD surface treatment contributes to extended cutting performance and fewer insert changes, resulting in lower tooling costs per component and more stable production throughput. For shops prioritising process security and straightforward tooling logistics, this insert represents a cost-effective component in an optimised turning toolset.

FAQ

What materials is this insert suitable for? This insert is specified for machining steel and stainless steels; the AH725 grade provides universal, fracture-resistant performance across those material groups.

How does the chipbreaker affect machining? The single-sided chipbreaker promotes controlled chip formation for general turning operations, assisting chip evacuation and helping to protect the cutting edge during interrupted cuts.

Is the insert compatible with existing ISO TCMT holders? Yes, the insert follows the ISO TCMT090204 dimensions and is compatible with holders and boring bars designed for ISO TCMT inserts when size, thickness and hole style match.

What does the 0.4 mm corner radius mean for surface finish? A 0.4 mm corner radius balances edge strength and accessibility; it supports good surface finish while providing greater resistance to edge chipping compared with smaller radii.

How many cutting edges are available per insert? The triangular ISO form offers multiple indexable edges; indexing the insert restores a fresh cutting edge without replacing the insert body.
