The combination of a PVD-coated carbide grade, ISO triangular geometry and a secure cylindrical hole with countersink ensures stable clamping and consistent performance — order directly via Metav Werkzeuge or contact our consultants for application details.

TPMT110302 AH725 Tungaloy – ISO triangular turning insert, PVD-coated carbide, 60° geometry

The TPMT110302 AH725 is a triangular ISO turning insert for external and internal turning, engineered as a universal, fracture-resistant grade for Stahl and rostfreier Stahl and compatible with standard 60° holders.

• PVD-coated AH725 for high wear resistance
• Universal grade for Stahl and rostfreier Stahl
• ISO triangular insert, 60° geometry
• Cylindrical hole with countersink 40°–60°

Stable machining even with mixed materials

The PVD-coated AH725 grade delivers a balance between toughness and wear resistance that suits variable workshop demands. As a carbide insert with a fracture-resistant formulation, it is particularly effective where material batches include both Stahl and rostfreier Stahl. The practical benefit is fewer insert changes and a steadier cycle time; for operations with smaller tool overhangs or higher demands on process security, this results in more predictable throughput and less scrap. The coating also helps reduce adhesive build-up at elevated cutting temperatures, improving surface finish and tool life.

Secure clamping and precise geometry for consistent cuts

The triangular shape with a nominal cutting angle of 60° and a relief angle of 11° provides a robust support surface in standard toolholders. The insert’s cylindrical hole with one-sided countersink (40°–60°) ensures accurate seating and repeatable clamping by the screw, reducing micro-movements that can degrade dimensions. A corner radius of 0.2 mm supports finishing passes without compromising strength. Together these features improve dimensional stability and make holder compatibility straightforward when the correct form, clearance, tolerance class, fastening and thickness are observed.

Coating and grade explained for better decision-making

The PVD-coated layer on this insert increases resistance to abrasive wear while preserving edge toughness. For customers less familiar with coating technology: PVD (physical vapour deposition) forms a thin, hard film that reduces flank and crater wear without significantly softening the cutting edge. The result is a longer interval between indexings and consistent surface quality. Selecting the AH725 sort offers a universal compromise: better fracture resistance than some harder grades, and improved wear control compared with uncoated grades—ideal for workshops machining mixed steels and rostfreier Stahl.

Practical workshop advantages and setup notes

This ISO insert is supplied in the standard TPMT110302 format and matches common ISO toolholders when the holder’s specifications—form, clearance angle, tolerance class, fastening, size and thickness—are observed. The plate thickness of 3.18 mm and compact 11 mm size make it suitable for light to medium-duty turning where secure seating and small radii are required. The single-sided chipbreaker design promotes predictable chip flow for many turning tasks, reducing the risk of tangling and supporting stable, repeatable cycles on both external and internal operations.

FAQ

What materials is this insert suitable for?
The answer: The TPMT110302 AH725 insert is intended primarily for Stahl and rostfreier Stahl, offering a universal balance between toughness and wear resistance for mixed batches.

How does the PVD coating affect performance?
The PVD-coated AH725 grade reduces abrasive wear and helps maintain a sharper edge at higher temperatures, so the insert sustains longer cutting intervals in turning applications.

Which holder features are required for correct fitment?
Correct fitment depends on holder form, clearance angle, tolerance class, fastening method, size and thickness; the TPMT110302 format matches standard 60° triangular holders when these parameters are observed.

Is this insert suitable for finishing passes with small radii?
Yes, the 0.2 mm corner radius and the 3.18 mm plate thickness support fine finishing cuts while maintaining edge robustness for light to medium-duty operations.

Does the insert include a chipbreaker?
Yes, the insert features a one-sided chipbreaker designed to promote controlled chip evacuation during turning.
