TPMT090204 AH725 indexable turning insert — triangular ISO insert for turning, universal grade AH725 by Tungaloy

ISO-standard triangular insert PVD-coated carbide grade AH725 Single-sided chipbreaker for stable chips 0.4 mm corner radius, 60° included angle

Consistent performance for general turning applications

The TPMT090204 AH725 insert is an ISO-standard triangular cutting element designed for routine external and internal turning. Its PVD-coated carbide construction ensures good wear resistance while the AH725 grade provides a balance between toughness and edge stability, which is advantageous when machining both alloyed steel and stainless steels. The result is fewer interruptions, repeatable turning cycles and predictable tool life—important when planning batch production or mixed-material runs.

Stable chip control and surface quality

A single-sided chipbreaker integrated into the geometry promotes reliable chip formation and evacuation, reducing the risk of built-up edge and improving surface finish on the workpiece. The 0.4 mm corner radius contributes to edge strength and a controlled cutting action, which together with the insert’s geometry helps to maintain consistent component tolerances and minimises secondary finishing operations, saving time on downstream processing.

Flexible fit and secure clamping for toolholders

Compatibility with toolholders is determined by form, clearance angle, tolerance class, fastening style, size and thickness; this insert is produced to ISO specifications for straightforward interchangeability. The insert’s cylindrical hole with a single-sided countersink (40°–60°) and a thickness of 2.38 mm enable secure mounting in common external holders or boring bars, promoting stable cutting conditions and repeatable indexability when rotating cutting edges to a fresh corner.

Process security and economical machining

The combination of a universal, break-resistant grade and the PVD coating makes this insert suitable where process reliability is critical, especially in applications with variable workpiece materials or smaller tooling. A consistent edge life reduces scrap and tool-change downtime, supporting higher productivity and predictable manufacturing costs. The geometry’s 60° included angle and 11° clearance support stable engagement and effective force distribution during turning.

FAQ

What materials is this insert suitable for?
The TPMT090204 AH725 insert is intended primarily for steel and stainless steels; the AH725 grade delivers a universal, break-resistant performance across a broad material range.

How does the chipbreaker influence machining?
The single-sided chipbreaker on this Tungaloy insert promotes controlled chip formation and evacuation, improving process stability and surface quality during turning.

Is the insert compatible with standard ISO toolholders?
Yes. The insert is manufactured to ISO dimensions and interfaces (form, size and hole geometry) to ensure compatibility with common external holders and boring bars.

What are the key geometry values to consider when setting up the tool?
Important values include the 0.4 mm corner radius, 2.38 mm plate thickness, 11° clearance and 60° included angle for correct holder selection and cutting parameter calculation.

Can the insert be indexed to a fresh cutting edge?
Yes. The triangular shape provides multiple cutting edges that can be rotated and indexed, extending usable life before replacement.
