TNMG160404 AH8015 ISO turning insert — PVD-coated cemented carbide, 0.4 mm radius (Tungaloy)

the TNMG160404 AH8015 is an ISO‑standard triangular turning insert designed for general external and internal turning of heat‑resistant alloys, offering balanced wear resistance and edge stability

• ISO triangular insert TNMG160404, 0.4mm corner radius
• PVD-coated cemented carbide AH8015 for heat-resistant alloys
• Double-sided chipbreaker for balanced cutting performance
• Cylindrical hole fixing; compatible with ISO holders

Consistent edge life through a balanced grade

The insert is manufactured from PVD-coated cemented carbide, grade AH8015, which has been selected as a first choice for general machining of heat‑resistant alloys. The combination of coating and substrate provides a balance between wear resistance and edge stability, reducing unexpected tool changes and increasing effective production time. The PVD layer enhances resistance to high temperature at the cutting zone, while the base carbide ensures dimensional stability during interrupted cuts.

Predictable clamping and straightforward integration

Designed to the ISO form TNMG160404, the component is compatible with standard external holders and boring bars when matched for form, clearance angle, tolerance class, attachment method, size and thickness. The cylindrical hole ensures secure locating and repeatable clamping forces, which translates into consistent cutting geometry and improved part tolerances. Using ISO‑matched tooling reduces setup iterations and helps maintain flow across multi‑machine shops.

Improved process stability with active chip control

The insert is double‑sided with an integrated chipbreaker, optimised to produce regular chips and avoid tool or machine interruptions. Effective chip control supports higher uninterrupted cutting times and reduces secondary handling, contributing to a measurable productivity gain. When aligned with appropriate cutting data, this geometry supports stable surface finish and lowers cycle time, making the trade‑off between performance and tool cost more favourable for series production.

Application guidance and recommended use cases

Intended for turning operations, the insert suits both external and internal profiles where workpieces demand thermal stability at the cutting edge. Select the chipbreaker and grade in accordance with material, machining strategy and machine rigidity to achieve the best economy per part. Shops machining advanced alloys will benefit most from the balanced performance of this insert, which helps to extend tool life and improve process reliability without complex parameter tuning.
