TPMT 130304 AH725 — ISO turning insert, PVD-coated carbide (Tungaloy)

TPMT 130304 AH725 is an ISO-standard triangular turning insert designed for external and internal turning, offering a universal, breakage-resistant grade for steel and stainless steels.

• PVD-coated carbide for high wear resistance
• Universal AH725 grade for steel and stainless
• ISO triangular insert with secure central hole
• 0.4 mm corner radius for stable edge strength

Reliable cutting performance under varied conditions

This ISO triangular insert combines a PVD-coated hardmetal substrate with the AH725 grade to deliver reliable cutting behaviour across mixed batches of carbon and stainless steels. The coating reduces flank wear and helps maintain a consistent cutting edge over longer cycles, which translates into fewer interruptions for insert changes and a more predictable process. With the geometry geared towards both finishing and moderate roughing tasks, the insert contributes to reproducible surface quality and stable tool life, supporting higher overall productivity in turning applications.

Simple integration with ISO holder systems

The insert follows ISO dimensions and mounting conventions, so compatibility is achieved via matching form, clearance angle and size with the chosen holder, clamping kit and mounting screw. The triangular shape and central cylindrical hole with a one-sided countersink ensure secure clamping and accurate positioning in standard ISO turning holders. Specified values such as 3.18 mm thickness, a 60° cutting geometry and an 11° clearance make selection straightforward when replacing inserts or setting up new tool assemblies, reducing setup time and minimising trial-and-error on the shop floor.

Improved chip control and application guidance

Equipped with a PM chipbreaker, the insert is aimed at controlled chip formation during both external and internal turning. The modest 0.4 mm corner radius balances edge strength and surface finish: it reduces the risk of edge chipping while still enabling close tolerance finishing. For best results, select the chipbreaker and grade according to workpiece material and fixture stability; the AH725 grade is particularly suited to mixed production where process security and consistent performance are priorities. These choices contribute directly to lower scrap rates and steadier cycle times.

FAQ

Is this insert suitable for stainless steel?

The TPMT130304-PM AH725 is designed as a universal, breakage-resistant grade for steel and stainless steels and performs well under mixed-material production.

What are the key geometry values to check for holder compatibility?

Check the 60° cutting geometry, 11° clearance angle and 3.18 mm thickness; these values determine compatibility with ISO holders and clamping kits.

Which chipbreaker does the insert use and what is the benefit?

The PM chipbreaker promotes controlled chip formation during turning, improving chip evacuation and reducing the risk of tangling in both external and internal operations.

How does the 0.4 mm corner radius affect machining?

A 0.4 mm corner radius increases edge strength and reduces the likelihood of chipping while still permitting good surface finish and tolerance control in finishing passes.

Can the insert be used for internal turning as well as external turning?

Yes, the ISO-standard triangular design and PM chipbreaker make it suitable for both external and internal turning, especially where process security and variable workpiece materials are factors.
