TNMU 070304 AH3225 TNMU070304 — Tungaloy indexable milling insert, PVD-coated carbide, 60°

A TNMU070304 AH3225 indexable insert designed for milling operations in compatible Tungaloy milling systems, offering a sharp cutting edge and robust process security.

• PVD-coated carbide grade AH3225
• Triangular form for three cutting edges
• Double-sided chipbreaker for stable chips

Precision geometry for consistent cutting performance

The insert delivers a defined 60° cutting geometry and a 0.4 mm corner radius, which together ensure predictable engagement with the workpiece and uniform tool life. The triangular shape provides multiple usable edges per insert, reducing tool changes and maintaining production continuity. The insert’s double-sided chipbreaker supports controlled chip formation across planing, shoulder and slot milling, translating into consistent surface finish and fewer interruptions during machining.

Durable PVD-coated carbide for dependable edge retention

Manufactured from carbide and finished with a PVD coating, the grade AH3225 is optimised for wear resistance and fracture toughness under typical milling loads. This combination preserves a sharp cutting edge and extends the interval between indexings, benefiting cycle-time efficiency and lowering tooling consumption in the long run. Where process security and a resilient cutting edge are required, this grade offers a balanced solution between longevity and cutting performance.

System compatibility and practical mounting features

The insert is intended for use in Tungaloy milling systems: correct match of insert seat, geometry and cutter body is essential for secure clamping and repeatable results. It is supplied with a hole, featuring a cylindrical bore plus a double-sided countersink (40°–60°), allowing reliable location and clamping in appropriately designed cutters. The 3.18 mm thickness and triangular form deliver mechanical stability that supports higher feed rates without compromising the insert’s integrity.

Versatility across milling tasks and straightforward logistics

Suitable for face, shoulder, slot, high-feed and contour milling, the insert adapts to a wide range of machining tasks depending on the assigned cutter family. The combination of a compact corner radius and robust grade makes it suitable for operations where a fine edge and process reliability are required. Supplied under SKU 6824035-Tungaloy, the component is straightforward to order and integrate into existing tool inventories, simplifying procurement and inventory control.
