TPMT110204 AH725 TPMT turning indexable insert, 60° triangular, by Tungaloy

The TPMT110204 AH725 is an ISO-conforming triangular indexable insert designed for external and internal turning, offering a universal, fracture-resistant grade for steel and stainless steel applications.

• PVD-coated carbide grade AH725
• Universal, fracture-resistant for steel and stainless
• 60° triangular form with 0.4 mm corner radius
• Central hole with 40°–60° countersink

Consistent process security through robust grade and coating

The combination of a PVD-coated surface and the AH725 carbide grade delivers a balance of wear resistance and toughness suited to variable component batches and intermittent interrupted cuts. This indexable insert reduces the frequency of edge failures in demanding operations, which directly supports longer uninterrupted cycle times and fewer tool changes. Compatibility within the ISO insert family ensures predictable replacement routines, while the universal nature of the grade allows use across a broad range of steels and stainless steels without frequent grade swaps.

Geometry engineered for repeatable surface quality and chip control

A 60° triangular form with a 0.4 mm corner radius provides a compromise between strength and fine finishing capability: the 60° included angle stabilises cutting forces, while the 0.4 mm radius improves edge life and surface integrity on external profiles. The one-sided chipbreaker and the central hole with a single-side countersink (40°–60°) support reliable chip flow and secure seating in the toolholder, reducing chatter and producing consistent part finish on both long and short runs. The 2.38 mm plate thickness helps maintain rigidity in smaller tool assemblies.

Simple integration into ISO-based turning systems

Delivered as part of an ISO insert system, the package assumes use with a matching external holder or boring bar, plus the necessary underlay/clamping set and spare screws. Secure clamping is achieved by the cylindrical hole and the specified countersink geometry, which together prevent micro-movement and ensure repeatable positioning after index changes. Selection of the appropriate chipbreaker and insert grade should follow an assessment of workpiece material, cut depth and machine/tool stability, thereby aligning productivity goals with process reliability.

Applications that benefit from the TPMT design

This insert is particularly suitable for machining shops performing both external and internal turning where a flexible, robust solution is required for steels and stainless steels. The compact triangular format works well for smaller tools and setups where tool change frequency must be minimised without sacrificing surface quality. Brand-recognised manufacturing standards support predictable results and help maintain machining consistency across batches and operators.

FAQ

What materials is the TPMT110204 AH725 suitable for?
The TPMT110204 AH725 insert is designed primarily for steel and stainless steel, its fracture-resistant AH725 grade allowing reliable performance across mixed batches.

How does the 0.4 mm corner radius affect finishing?
A 0.4 mm corner radius on the TPMT110204 AH725 balances edge strength with surface finish, improving part quality while extending edge life under moderate feeds.

Which holders are compatible with this ISO insert?
Compatibility depends on holder form, relief angle, tolerance class, mounting and insert thickness; the TPMT110204 AH725 fits any ISO holder matching those parameters.

Is the insert supplied with clamping hardware?
The insert is intended for use within a system comprising an ISO insert, matching external holder or boring bar, underlay/clamping set and spare screws, which should be procured as required.

What is the purpose of the countersunk central hole?
The cylindrical hole with a 40°–60° single-side countersink secures the insert in the pocket and ensures repeatable seating and clamping for stable machining with the TPMT110204 AH725.
