TNMG 160404 AH8015 — Indexable turning insert, PVD‑coated carbide, 60° by Tungaloy

TNMG160404 AH8015 is an ISO‑standard indexable insert for general turning of heat‑resistant alloys and similar materials

• ISO 160404 triangular insert
• PVD‑coated cemented carbide grade AH8015
• Double‑sided chipbreaker geometry
• Cylindrical hole for secure clamping

Consistent performance for turning heat‑resistant alloys

The insert is manufactured from cemented carbide with a PVD coating, a combination engineered to balance wear resistance and edge stability when machining demanding alloys. This grade is specified as AH8015 and is suited as a first choice for the general machining of heat‑resistant materials; the coating improves abrasion performance while helping to maintain a dependable cutting edge. The result is fewer unscheduled insert changes and a more predictable tool life, which supports efficient production planning and reduces process variability.

Geometry and compatibility that simplify tool selection

The triangular plate offers a 60° cutting angle with a 0.4 mm corner radius and a plate thickness of 4.76 mm, dimensions that provide repeatable positioning and good access in both external and internal turning tasks. The insert is double‑sided, providing multiple cutting edges before replacement, and features a cylindrical hole for positive clamping. Compatibility with ISO‑standard toolholders is governed by form, clearance angle, tolerance class, fastening method, size and thickness; selecting a matching holder and clamping set ensures correct seating and consistent cutting performance.

Practical shop‑floor advantages

Using an indexable insert reduces downtime compared with brazed or solid tools because individual edges can be rotated or replaced quickly. The double‑sided chipbreaker improves chip control across varying depths of cut, which helps maintain surface quality and reduces the likelihood of chip entanglement. For stable processes, pair the plate with a holder suited to the workpiece rigidity and machining strategy; choosing the correct chipbreaker and grade according to material and machining stability yields measurable gains in cycle time and tool life.

Guidance for selecting grade and process setup

The AH8015 grade is designed as a versatile option that balances tool life and edge strength for heat‑resistant alloys and comparable materials. When higher edge stability or different wear characteristics are required, consider alternative grades or coatings matched to the workpiece and cutting conditions. For precise matching of insert geometry, holder type and clamping hardware, Metav Werkzeuge can advise on the appropriate components to achieve the desired surface finish and process reliability.

FAQ

Which materials is this insert best suited for?
The AH8015 grade is intended primarily for the general machining of heat‑resistant alloys; the PVD‑coated cemented carbide in the TNMG160404 AH8015 insert offers a balance of wear resistance and edge stability for these materials.

Is the insert indexable on both sides?
Yes, the plate is double‑sided, providing multiple usable edges before replacement and improving cost efficiency per insert.

How is holder compatibility determined?
Compatibility with toolholders follows ISO standards and depends on form, clearance angle, tolerance class, fastening, size and thickness; for TNMG160404 AH8015 (SKU: 6947352‑Tungaloy), match the insert geometry to the holder and secure with the appropriate clamping set.

Can this insert be used for internal turning operations?
Yes, the triangular geometry and compact dimensions make the insert suitable for both external and internal turning, provided an appropriate holder is used for reach and rigidity.

What practical benefits does the PVD coating provide?
The PVD coating enhances abrasion resistance and helps maintain cutting edge integrity during machining of tougher alloys, contributing to more consistent tool life and surface finish.
