TPMT090202 AH725 TPMT — ISO turning insert, PVD-coated carbide, Tungaloy

A TPMT090202 AH725 ISO turning insert designed for external and internal turning applications, featuring a 60° triangular form and an 11° clearance angle for versatile, secure metalcutting.

PVD-coated carbide grade AH725
60° triangular insert, 0.2 mm corner radius
Single-sided chipbreaker, hole with countersink
ISO 09 size, 2.38 mm thickness

Proven performance for mixed-material turning

The PVD-coated AH725 grade is formulated as a universal, chipbreak-resistant option for machining steel and rostfreier Stahl, delivering stable cutting-edge life where workpiece materials vary. PVD coating improves wear resistance and reduces built-up edge tendency, which translates into longer tool life and fewer interruptions. The combination of the PVD layer and the carbide substrate gives a balance between toughness and hardness, making the insert particularly suitable for smaller tools and operations demanding high process security. For shops requiring predictable results across a range of components, this insert minimises downtime and supports steady productivity.

Geometry that supports accuracy and surface quality

The triangular 60° form with a 0.2 mm corner radius provides predictable tool engagement and straightforward programming for turning cycles. The 11° clearance angle reduces rubbing on the flank and helps preserve dimensional accuracy and surface finish during external and internal turning. The single-sided chipbreaker promotes controlled chip formation in common cutting conditions, lowering the risk of entanglement and improving swarf handling. For less experienced operators, these geometric choices simplify setup and make achieving repeatable tolerances easier, while experienced machinists benefit from reduced trial-and-error when optimising feeds and speeds.

Compatibility, mounting and system considerations

As an ISO-standard insert, the plate is compatible with holders when form, clearance angle, tolerance class, fastening method, size and thickness are matched. The TPMT090202 variant includes a cylindrical hole with a one-sided countersink (40°–60°) to suit standard clamping arrangements, while the 2.38 mm plate thickness and ISO 09 size ensure interchangeability with common external holders or boring bars. When integrating into a tool system, confirm the tolerance class and fastening geometry to preserve clamping stability; correct seating and torque of the clamping screw are decisive for achieving the advertised repeatable performance.

Practical benefits and recommended use cases

Select this insert where a robust all-rounder is needed: frequent material changes, smaller tool shanks, or operations where process reliability outweighs maximised material removal rates. The AH725 grade supports productive machining with good edge stability and broad material coverage, reducing the need for multiple grades in mixed-production environments. For finishing passes on shaft work or medium-duty turning of components in batch production, the insert offers consistent surface quality and service life, helping to streamline tooling inventories and simplify tool management.

FAQ

What materials is this insert suitable for?
The TPMT090202 AH725 insert from Tungaloy is specified for machining steel and rostfreier Stahl, offering reliable chip control and edge stability across those materials.

Which holder types are compatible with this ISO insert?
Compatibility depends on form, clearance angle, tolerance class, fastening and size; the TPMT090202 fits standard ISO triangular holders and boring bars designed for ISO 09 plates.

How does the AH725 grade affect tool life?
The PVD-coated AH725 grade enhances wear resistance and edge stability, typically extending in-process life and supporting reproducible results in mixed-material production.

Can this insert be used for both external and internal turning?
Yes, the geometry and mounting hole with countersink make the insert suitable for both external and internal turning when paired with the appropriate holder.

What chip control can be expected from the single-sided chipbreaker?
The single-sided chipbreaker promotes controlled chip formation under common turning conditions, improving swarf evacuation and lowering chip-related interruptions.
