TPMT 16T308 AH725 — ISO turning insert, triangular 60°, Tungaloy

The TPMT 16T308 AH725 is an ISO-standard triangular turning insert designed for external and internal turning, combining a PVD-coated carbide substrate with a PM chipbreaker for dependable chip control in varied steels.

• PVD-coated carbide AH725 for steel and stainless steel
• 60° triangular insert with 0.8 mm corner radius
• PM chipbreaker for secure chip control
• Compatible with ISO holders with central hole

Reliable chip control for consistent cycle times

The combination of the PM chipbreaker and the AH725 cutting grade delivers predictable chip formation and evacuation, which directly supports shorter cycle times and fewer interruptions. The PVD coating provides a hard, wear-resistant surface that reduces built-up edge on stainless steels while maintaining sharp cutting performance in common alloyed steels. In practice, this means fewer insert changes and a more consistent surface finish across batches, helping to sustain throughput without sacrificing process security.

Simple integration into ISO tooling systems

The insert follows ISO geometry and is specified with a 60° included angle, 11° clearance, 16 mm size and 3.97 mm thickness, ensuring compatibility with established turning holders when form, clearance angle, tolerance class, fixing method, size and thickness are matched. The central cylindrical hole with a single-sided countersink (40°–60°) supports secure clamping and repeatable seating. These standardised dimensions make tool-pool management easier and reduce set-up time when swapping inserts between machines.

Durable edge and broad material coverage for process security

Manufactured from carbide and finished with PVD treatment, the grade is described as a universal, fracture-resistant choice for both steel and stainless steel, especially where material mixes or smaller tooling demands high reliability. The 0.8 mm corner radius balances edge strength and finish capability, enabling light to moderate finishing passes while resisting chipping in interrupted cuts. For production environments that prioritise continuity, this specification supports longer effective tool life and stable part quality.

FAQ

What materials is this insert suited for?

The TPMT 16T308 AH725 is specified for steel and stainless steel work, with the AH725 PVD-coated carbide grade offering universal, fracture-resistant performance across those materials.

How does the PM chipbreaker affect machining?

The PM chipbreaker on this insert supports controlled chip formation and evacuation; the result is improved process stability and reduced risk of chip-related interruptions when turning steels.

Which holder compatibility factors must be checked?

Compatibility is determined by insert form, clearance angle, tolerance class, fixing method, size and thickness; the TPMT 16T308 AH725 uses a central cylindrical hole with a single-sided countersink for secure clamping.

Is the corner radius suitable for finishing operations?

With a 0.8 mm corner radius, the insert provides a balance between edge strength and surface finish capability, suitable for light finishing passes and stable performance in interrupted cuts.

Can the AH725 grade be used for mixed-material production runs?

Yes, the AH725 grade is designed as a universal, breakage-resistant option for varied steels and stainless steels, making it practical for production environments with changing materials.
