TPMT130304-PS AH725 — TPMT 130304 AH725 turning insert by Tungaloy (PVD-coated carbide)

The TPMT130304-PS AH725 is an ISO-indexable triangular turning insert designed for external and internal turning applications, offering universal performance for Stahl and rostfreier Stahl with a PS chipbreaker for controlled chip formation.

• PVD-coated carbide AH725 for Stahl and rostfreier Stahl
• PS chipbreaker for reliable chip control
• Triangle ISO insert 13 mm, 0.4 mm corner radius
• Cylindrical hole with one-sided countersink (40°–60°)

Boosted process reliability through PVD-coated carbide

The PVD-coated carbide grade AH725 is engineered to deliver process reliability across a range of turning operations. Coating hardness and adhesion reduce flank wear and substrate exposure, which extends cutting life and limits unplanned tool changes. For workshops processing mixed batches or frequent material changes, the universal, fracture‑resistant grade supports consistent cycle times and helps maintain throughput. The balanced combination of coating and substrate material minimises thermal and mechanical wear mechanisms that typically shorten insert life.

Consistent edge geometry for reproducible surface quality

A defined insert geometry — including the 60° included angle and 0.4 mm corner radius — ensures a stable cutting edge with predictable material engagement. The modest corner radius provides a robust edge for general turning while contributing to a consistent surface finish, especially when finishing passes are required. Edge strength and radius selection are decisive for avoiding edge chipping when machining interrupted cuts or variable cross-sections; the radius specified here helps to balance edge life and achievable roughness without the need for frequent rework.

ISO sizing and mounting designed for quick changeovers

Manufactured to the ISO series for triangle inserts, the 13 mm size and 3.18 mm thickness enable compatibility with a wide range of triangular holders. The insert is supplied with a cylindrical hole and a one-sided countersink (40°–60°) to secure mounting and repeatable clamping. Compatibility with a toolholder is determined by form, clearance angle, tolerance class, fastening method, size and thickness; these parameters ensure secure seating and accurate repeatability when inserts are indexed or changed, reducing setup time and maintaining component tolerances.

Optimised chip control and versatile application range

The PS chipbreaker supports controlled chip formation across turning tasks, making it suitable for both roughing and light finishing passes in Stahl and rostfreier Stahl. The fracture-resistant nature of the grade is particularly advantageous for smaller tool geometries and operations that place a premium on process stability. By selecting the matching chipbreaker and grade, machining cycles are stabilised, surface integrity is preserved and tool life is extended — delivering measurable productivity gains on batch and single-piece production alike.
