Longer tool life through a wear-resistant coating

The insert's PVD-coated carbide grade AH120 delivers a wear- and fracture-resistant cutting edge, which extends service intervals and reduces machine downtime. As an ISO-standardised indexable insert, the design supports repeatable seating and secure clamping, contributing to stable cutting conditions and reproducible component quality. The combination of coating and substrate is aimed at conserving edge integrity where a sharp geometry and process reliability are required.

Consistent chip control and reliable cutting performance

A double-sided chipbreaker on the triangular plate improves chip formation under varied cutting conditions, helping to avoid built-up edge and uncontrolled chip flow. The insert's geometry — 60° main angle with a 1.2 mm corner radius — provides a balance between strength and fine surface finish, allowing effective material removal while maintaining the cutting-edge robustness needed for medium to demanding turning tasks. Selecting the appropriate chipbreaker style and grade helps match the insert to workpiece material and machining stability.

Easy integration into ISO tool systems for faster setup

Compatibility with standard indexable holders is determined by the insert form, clearance angle, tolerance class, attachment method, size and thickness. The TNMG form and the cylindrical hole ensure positive mechanical location and tightening in the seat, while the 6.35 mm plate thickness and 27 mm size offer stable support under cutting forces. This standardisation reduces set-up time and simplifies inventory management when multiple holders or backup inserts are required.

Practical application guidance for turning tasks

Designed for both external and internal turning, this insert is best used where a sharp cutting edge and secure process behaviour are priorities; the AH120 grade is specifically formulated to resist wear and chipping during turning. For best results, match the chipbreaker and grade selection to the workpiece material, machining parameters and setup rigidity.

FAQ

What is the primary use of this insert?
The TNMG270612 AH120 insert is intended for external and internal turning operations where a sharp cutting edge and process security are required; it is an ISO-standard triangular indexable insert from Tungaloy (SKU 6808698-Tungaloy).

Which cutting conditions suit the AH120 grade best?
The AH120 PVD-coated grade is tailored for applications needing wear resistance and reduced edge chipping during turning; choose the chipbreaker and cutting data according to the workpiece material and the rigidity of the setup.

How is the insert mounted in the tool holder?
The insert locates on a matching seat and is clamped using the central cylindrical hole; compatibility depends on form, clearance angle, tolerance class, attachment method, size and thickness of the insert and holder.

Can both sides of the insert be used?
Yes, the insert is double-sided with a reversible cutting geometry, allowing indexing to a fresh cutting edge once one edge is worn, increasing usable edges per insert.

What are the key dimensions to check for holder compatibility?
Important dimensions are the 27 mm size, 6.35 mm thickness, 60° triangular form and 1.2 mm corner radius; verify these against holder specifications and tolerance classes for correct seating.
