TPMT 130308 AH725 Turning insert (ISO TPMT130308-PSS, PVD carbide) — Tungaloy

The TPMT130308-PSS AH725 is an ISO‑standard triangular indexable insert for external and internal turning, engineered for universal performance with steels and stainless steels.

• PVD-coated universal grade AH725
• 60° triangular geometry for general turning
• ISO compatibility via form, clearance and size
• 0.8 mm corner radius for robust cutting edge

Consistent machining across varied steels

The PVD‑coated AH725 grade is a carbide formulation designed for predictable wear behaviour when machining carbon steels and stainless steels. The coating improves heat resistance and adhesion while reducing built-up edge, which translates into longer tool life and fewer interruptions. For shops facing frequent material changes, this indexable insert offers a balance between wear resistance and toughness that helps maintain cycle times and surface finish without specialist parameter tuning.

Secure seating and compatibility for fast tool changes

Compatibility with conventional toolholders is determined by the insert’s shape, 11° relief (facing) angle, tolerance class, clamping method and thickness. The triangular format with a central hole and a single‑side countersink (40°–60°) enables reliable indexation on ISO‑type holders and boring bars, permitting quick insert changes and minimising downtime. Clear information on form and tolerance supports correct selection of the matching carrier, reducing setup error and maintaining repeatability in serial production.

Edge geometry that stabilises the process

A 60° wedge angle combined with a 0.8 mm corner radius produces a strong cutting edge that resists chipping under interrupted cuts and light roughing operations. The PSS chipbreaker geometry is intended to control swarf and promote stable chip flow for the specified material range; this reduces vibration and contributes to better surface quality. For operators less familiar with chipbreaker behaviour, the insert’s shape and radius provide an inherently forgiving cutting response that simplifies feed and speed choices.

Practical selection guidance and economic benefits

Choosing the correct chipbreaker and grade depends on workpiece material, rigidity of the setup and required surface finish. In many mixed‑material production scenarios, the universal AH725 grade reduces inventory complexity by covering a broad spectrum of steels and stainless steels while offering dependable edge life. The combination of a PVD coating and a robust geometry supports consistent parts output and fewer tool changes, yielding measurable time savings in batch production and higher overall process productivity.

FAQ

What materials is this insert suited for?
The TPMT130308‑PSS AH725 insert is designed primarily for a wide range of steels and stainless steels, offering a universal balance of toughness and wear resistance.

How does the PSS chipbreaker affect cutting performance?
The PSS chipbreaker promotes controlled chip formation and evacuation; with the AH725 grade it helps reduce vibration and improve surface finish during general turning.

Is the insert compatible with standard ISO toolholders?
Yes; the insert follows ISO dimensions (130308) and is compatible with ISO‑type holders when matched by form, clearance angle, tolerance class and clamping arrangement.

What does the 0.8 mm corner radius mean for operation?
A 0.8 mm corner radius strengthens the cutting edge against chipping and is suited to stable roughing and finishing passes where a balance of edge life and surface quality is required.

Can the AH725 grade reduce tool inventory complexity?
Because AH725 is a universal, fracture‑resistant grade for steels and stainless steels, it often allows consolidation of grades across varying workpiece materials, simplifying stock and selection.
