TPMT 130308 AH725 – Turning indexable insert (ISO) by Tungaloy

A TPMT 130308 AH725 triangular ISO indexable insert designed for external and internal turning, offering a universal, fracture‑resistant PVD‑coated carbide grade for mixed material machining.

• PVD-coated carbide grade AH725
• Universal for Stahl and rostfreier Stahl
• 60° triangular geometry for stable turning
• 0.8 mm corner radius for fine finishes

High uptime through material and coating choice

The combination of a PVD-coated surface and the AH725 carbide grade is aimed at stable chip formation and extended edge life when machining a range of materials. This optimises production time by reducing unplanned tool changes and supports predictable tool life, which is particularly valuable in mixed‑material lots. The design promotes process security and helps to maintain component tolerances with fewer interventions.

Compatibility that simplifies tool selection

The ISO indexable format ensures straightforward integration into standard tool holders; compatibility is governed by insert form, relief angle, tolerance class, fastening method, size and thickness. The triangular 60° geometry and the specified hole style facilitate secure clamping and repeatable seating in holders. Clear specification of dimensions and fit reduces set‑up time and minimises the risk of incorrect mounting, helping to maintain consistent cycle times.

Precision edge form for fine finishing and strength

With a 0.8 mm corner radius, the insert balances edge strength and surface finish capability. The moderately rounded corner supports higher feed options than a sharp edge while still achieving good surface quality in finishing passes. The PS chipbreaker supports controlled chip breaking across a variety of turning tasks, so fewer interruptions for chip management are required and surface integrity is preserved.

Practical guidance for productive turning

This insert is intended for turning (external and internal) where reliability and adaptability are priorities. Select the TPMT 130308 AH725 variant to harmonise cutting data across Stahl and rostfreier Stahl workpieces and to reduce tool change frequency. For confirmation of holder compatibility or cutting data recommendations, technical advisers are available and supply of replacement screws and clamping sets is straightforward through the tooling system.

FAQ

What materials is this insert suitable for? The TPMT130308-PS AH725 insert is specified for machining Stahl and rostfreier Stahl and performs well where mixed material batches require a universal, fracture-resistant grade.

Which insert geometry does the product use and what is its benefit? The product features a triangular 60° geometry that provides stable turning performance and secure clamping in standard ISO tool holders.

What is the corner radius and how does it affect surface finish? The corner radius is 0.8 mm; this radius offers improved edge strength while enabling a fine surface finish in many finishing and semi-finishing operations.

How is the insert held in the tool and what is the hole design? The insert uses a cylindrical hole with a one-sided countersink (40°–60°) for positive, repeatable clamping in compatible holder systems.

What identifiers should be used when ordering spare inserts? Order using the manufacturer article number 6856682 or the manufacturer SKU TUN6856682 to ensure delivery of TPMT130308-PS AH725 inserts.
