TNGU120708 AH120 — Tungaloy indexable milling insert (milling)

TNGU120708 AH120 is a triangular, PVD-coated cemented carbide indexable insert for Tungaloy milling systems, designed for face, shoulder, slot, high-feed and contour milling where a sharp cutting edge and reliable process security are required

• PVD-coated cemented carbide AH120
• 0.8 mm corner radius, 60° geometry
• Triangular form, double-sided chipbreaker
• Cylindrical hole with 40°–60° countersink

Consistent cutting edge and coating for dependable results

The AH120 grade combines a PVD-coated surface with a wear-resistant cemented carbide substrate to deliver a consistently sharp cutting edge and controlled flank wear. A physical vapour deposition finish forms a thin, hard layer that reduces adhesion and friction at the cutting zone; this means longer edge life and predictable tool-change intervals. The coating also aids surface integrity on the workpiece and contributes to process stability under moderate to demanding cutting conditions, supporting uninterrupted production cycles and predictable maintenance scheduling.

Precision geometry for accurate, secure clamping

The insert’s triangular shape and 60° cutting angle are complemented by a 0.8 mm corner radius and a plate thickness of 7.94 mm, providing a stable seat and repeatable positioning in compatible milling bodies. The component features a cylindrical hole with a double-sided countersink (40°–60°) to match common clamping systems; proper fitment ensures accurate heat transfer and rigid mounting. Note that plate seat, geometry and cutter body must be technically compatible to achieve rated performance and to preserve the integrity of the clamping interface.

Optimised chip control and targeted milling applications

A double-sided chipbreaker manages cut material for the range of typical operations—face, shoulder, slot, high-feed and contour milling—helping to avoid clogging and improve surface finish. The combination of the chipbreaker design and the AH120 grade is particularly useful when a sharp edge and process reliability are required simultaneously. This makes the insert well suited to medium-duty milling tasks where consistent part quality and minimal rework are priorities, while also providing economic tool utilisation through predictable wear behaviour.

Economical handling and system-level benefits

As an indexable solution, the insert delivers quick edge changes and reduced downtime compared with solid tooling; multiple cutting edges per plate support cost-effective consumption. The robust grade and geometry reduce the frequency of part rejections and support higher first-pass yields, contributing to lower overall machining costs. When integrated into a matched Tungaloy milling system, the insert aids in maintaining stable machining parameters and simplifies inventory by standardising on a proven insert geometry and grade.

FAQ

What materials is this insert intended for?
The AH120 grade insert is specified for general milling tasks where a sharp edge and process security are required; material suitability depends on the selected milling body and machining parameters.

How is the insert secured in the milling cutter?
The insert has a cylindrical hole with a double-sided countersink (40°–60°) designed to work with the matching clamping screw and cutter body; correct seat geometry ensures reliable fixation.

Can the insert be used on any milling system?
Plates of this family are intended for Tungaloy milling systems; the plate seat, geometry and cutter body must be technically compatible to achieve rated performance.

What benefits does the PVD coating provide?
The PVD-coated layer on the cemented carbide substrate improves wear resistance, reduces friction and helps maintain a sharp cutting edge, contributing to stable cutting conditions and longer edge life.

How many cutting edges are available per plate?
The triangular form provides multiple usable edges before indexing; the exact number depends on the specific micro-geometry and whether both sides are used.
