TNMU 070308 AH3135 indexable milling insert — Tungaloy, PVD-coated carbide, 60°

The TNMU070308 AH3135 is an indexable insert for Tungaloy milling systems, designed for face, shoulder, groove, high-feed and contour milling where a sharp cutting edge and process security are required.

• TNMU070308: triangular 60° insert, 0.8 mm radius
• PVD-coated carbide AH3135 for wear resistance
• Cylindrical hole with double countersink 40°–60°
• Double-sided chipbreaker for consistent chip control

Stable machining across diverse milling tasks

The AH3135 grade is a PVD-coated carbide developed for wear and chipping resistance, which supports longer tool life and steady performance in mixed-production environments. In practical terms, the coating reduces flank wear rates and helps maintain a sharp edge under fluctuating cutting conditions; this leads to fewer tool changes and more predictable cycle times. The insert’s suitability for face, shoulder, groove, high-feed and contour milling means it can standardise tooling across several operations, reducing inventory complexity while maintaining process reliability.

Geometry engineered for secure seating and repeatability

A triangular plate with a nominal 60° included angle and 0.8 mm corner radius provides a balance between edge strength and cutting definition. The geometry, combined with a 3.18 mm plate thickness and a cylindrical hole with a double-sided countersink, ensures precise seating and uniform clamping force when the correct clamping screw and seat geometry are used. This mechanical stability reduces vibration, improves surface finish and supports consistent dimensional outcomes on successive parts, which is essential for high-accuracy or high-volume production runs.

Predictable chips and simplified process setup

Integrated double-sided chipbreakers promote controlled chip formation over a wide range of cutting parameters, easing swarf evacuation and lowering the risk of re-cutting. The AH3135 grade’s resistance to chipping supports a reliably sharp cutting edge, which is particularly advantageous when machining interrupted cuts or mixed-material batches. As part of the full tool system — milling body, insert, clamping screw and, where applicable, backing pad — the component must be matched to the toolholder family to achieve the stated benefits. If unsure whether this insert meets specific requirements or additional technical data is needed, Metav Werkzeuge’s advisors are available to provide further guidance.
