CPMT09T308 AH8015 indexable turning insert by Tungaloy — PVD-coated carbide, 80° rhombic geometry

The CPMT09T308 AH8015 is an ISO-standard indexable insert for external and internal turning, optimised for machining heat-resistant alloys with predictable wear behaviour and consistent surface quality

• PVD-coated carbide AH8015
• ISO rhombic 80° geometry
• 0.8 mm corner radius
• Compatible with ISO turning holders

Consistent grade for demanding alloys and uptime

The AH8015 grade is a PVD-coated carbide developed as a balanced solution between wear resistance and cutting-edge stability, making it particularly suitable for machining heat-resistant alloys. The coating reduces adhesion and thermal softening at the cutting edge, which translates into longer intervals between indexings and fewer tool changes. For production environments focused on throughput, this grade supports consistent component quality while reducing downtime, so that cycle times remain predictable and scrap rates are lowered.

Geometry and rigidity designed for reliable surface finish

An 80° rhombic geometry with a 0.8 mm corner radius provides a stable engagement angle that helps to control cutting forces and vibration during turning. The nominal 11° relief angle and the plate thickness of 3.97 mm contribute to insert rigidity; together these factors help to maintain dimensional accuracy and repeatable surface finish across serial runs. Explaining briefly: the included angle and corner radius determine how load and heat are distributed at the cutting zone—smaller radii help when precision is required, while the rhombic form improves access for various contouring operations.

Secure fastening and simple integration into existing toolholders

Compatibility with holders is governed by form, relief angle, tolerance class, fastening method, size and thickness, and this ISO-format insert is designed to match common external holders and boring bars. The insert is supplied with a cylindrical hole and a single-side countersink (40°–60°), enabling secure clamping and straightforward indexing. Using a standard ISO clamping system reduces handling errors and makes inventory management easier, as holders, shims and spare screws form a simple system build for workshop integration.

Controlled chip formation and efficient production

The one-sided chipbreaker on this insert supports predictable chip formation for a range of cutting conditions, aiding chip evacuation and decreasing the risk of built-up edge. Combined with the PVD coating and the carbide substrate, this leads to a favourable cost-benefit ratio where tool life and surface integrity justify process consistency. In practical terms, the result is fewer interruptions for tool changes, improved surface quality and enhanced process reliability—attributes that directly support higher machine utilisation and lower per-part machining costs.

FAQ

What materials is this insert best suited for?
The CPMT09T308 AH8015 indexable turning insert is intended primarily for heat-resistant alloys, offering a good balance of wear resistance and edge stability for general turning operations.

Is the insert compatible with standard ISO holders?
Yes. The insert follows ISO dimensions (09T308) and is compatible with holders that match the form, relief angle, tolerance class, fastening and thickness; the cylindrical hole with countersink ensures secure clamping.

What does the AH8015 designation indicate?
AH8015 denotes a PVD-coated carbide grade engineered for first-choice performance on heat-resistant materials, providing improved tool life and stable cutting-edge behaviour under thermal stress.

Can this insert be used for internal machining as well as external turning?
Yes. The rhombic geometry and compact corner radius allow the insert to be used for both external and internal turning, with appropriate holder selection and cutting parameters.

How does the chipbreaker affect production stability?
The one-sided chipbreaker promotes controlled chip formation and evacuation, reducing the risk of interruptions from tangled chips and contributing to consistent surface finish and process reliability.
