TNMG 160404 AH8015 — Tungaloy turning insert for general turning (PVD-coated carbide, 60°)

TNMG 160404 AH8015 is a triangular ISO turning insert designed for general external and internal turning operations, optimised for machining heat-resistant alloys with consistent performance

• PVD-coated carbide for heat resistance
• Double-sided triangular geometry
• 0.4 mm corner radius for accurate profiles
• Cylindrical-hole ISO-compatible mount

Improved tool life through balanced grade and coating

The AH8015 grade combines a PVD-coated surface with a hard carbide substrate to deliver a favourable compromise between wear resistance and cutting-edge robustness. This balance reduces flank wear in multi-pass turning of tougher alloys and keeps tool change frequency low, enhancing overall process economics. The coating improves thermal stability at the cutting edge, which is particularly beneficial when working with heat-resistant alloys, where cutting zones run hotter than in standard steels.

Precise contours and repeatable geometry for reliable finishes

A triangular insert with a nominal size of 16 mm and a 60° included angle yields predictable approach geometry and a stable cutting line. The 0.4 mm corner radius supports the generation of defined profiles and consistent surface quality while the double-sided arrangement provides two usable edges per indexation, reducing inventory and downtime. These geometric characteristics translate directly into fewer set-up adjustments and reproducible component tolerances in serial production.

Seamless integration with ISO-compatible holders and secure clamping

Compatibility with toolholders is determined by the insert form, ISO code, clearance and fastening style; the TNMG 160404 specification and cylindrical hole facilitate secure mounting in standard clamping systems. The 0° clearance geometry simplifies seat design on the holder and ensures a predictable contact zone, which supports stability during interrupted cuts. Select the chipbreaker and grade according to the workpiece material and machining stability to achieve optimal chip control and tool life.

Practical handling and process benefits for workshop efficiency

A standardised ISO insert such as this reduces spare-part complexity: the combination of indexable edges and straightforward replacement enables rapid insert change and minimal machine downtime. Integration into a system—insert, holder and clamping set—allows predictable setup and consistent results across work shifts.

FAQ

What materials is this insert suitable for?
The TNMG160404 AH8015 Tungaloy turning insert (SKU 6947411-Tungaloy) is designed primarily for the general machining of heat-resistant alloys, offering a balance between wear resistance and edge stability

Is the insert single or double-sided?
This insert is double-sided, providing two usable cutting edges per indexation to reduce inventory and replacement frequency

How is the insert mounted in the holder?
Mounting is via a cylindrical hole and ISO-compatible seat; the TNMG160404 form and tolerance class determine correct holder selection and clamping method

What does the 0.4 mm radius mean for surface finish?
A 0.4 mm corner radius supports precise profile generation and consistent surface finish while offering a compromise between strength and edge definition

Can this insert be re-ground or are there recommended replacement practices?
Indexable inserts like the TNMG160404 AH8015 are typically replaced when worn; replacement ensures repeatable geometry and process reliability rather than re-grinding
