TPMT130302-PS AH725 — Indexable turning insert, PVD-coated carbide, 0.2 mm corner radius (Tungaloy)

TPMT130302-PS AH725 is an ISO-indexable turning insert designed for external and internal turning, offering a universal, breakage-resistant grade optimised for mixed-material production.

*ISO TPMT130302 triangular form *PVD-coated AH725 carbide grade *0.2 mm corner radius for precision *Suitable for steel and stainless steel

Stable cutting on mixed steels for fewer interruptions

The AH725 grade is a PVD-coated carbide developed as a universal, breakage-resistant solution for applications where the workpiece material varies between steel and stainless steel. Its chemistry and coating promote stable chip formation, reducing the risk of unexpected breakouts during shorter and smaller-tool operations. For production environments with frequent material changes, the insert helps maintain cycle times and reduces scrap rates by delivering consistent edge behaviour and longer usable life compared with untreated grades.

Geometry that delivers repeatable accuracy and secure clamping

The triangular insert features a 0.2 mm corner radius and an 11° relief angle, dimensions that support accurate dimensional control at the cutting edge while allowing controlled chip flow. The insert thickness of 3.18 mm and an inscribed circle of 13 mm combine with the cylindrical hole plus one-sided countersink (40°–60°) to ensure firm seating in the holder and predictable repeatability after index changes. These geometric details translate into fewer setup adjustments and a straightforward way to achieve target tolerances in series turning operations.

System compatibility and practical workshop advantages

As part of an ISO-indexable system, the insert functions within a straightforward assembly: matching external holder or boring bar, a suitable shim or clamp set, and replacement screws. Compatibility is determined by form, relief, tolerance class, fastening method, size and thickness; selecting the correct chipbreaker (PS) and grade supports process security and surface finish. For typical external and internal turning tasks the insert integrates easily into existing tool inventories, offering a balance of performance and flexibility for production and job-shop settings.

FAQ

What materials is this insert suitable for? The Tungaloy TPMT130302-PS AH725 insert is formulated for steel and stainless steel, offering universal performance across mixed-material production.

Which chipbreaker is supplied and when should it be chosen? The insert features the PS chipbreaker; select this chipformer for stable chip control in general turning and where process security is a priority.

How does the 0.2 mm corner radius affect finishing? A 0.2 mm corner radius provides a compromise between edge strength and fine surface finish, allowing precise dimensional control for finishing and light semi-finishing passes.

Is this insert compatible with all ISO triangular holders? Compatibility depends on the holder’s form, relief angle, tolerance class, fastening method, size and thickness; the ISO designation TPMT130302-PS indicates the standard form to match with appropriate holders.

Which components are required to build a complete tool assembly? A complete system comprises the insert, a matching external holder or boring bar, a shim/underlayer or clamp set and the correct fastening screw for secure mounting.
