TNMU 070308 AH3225 indexable milling insert — 60° triangular, PVD-coated, Tungaloy

The TNMU070308 AH3225 is an indexable triangular milling insert designed for general milling operations in Tungaloy-compatible milling systems and intended for face, shoulder, slot, high-feed and contour milling.

• Triangle insert TNMU 070308, 60° cutting angle
• PVD-coated carbide grade AH3225 for wear resistance
• Double-sided chipbreaker for reliable chip control
• Cylindrical hole with double-sided countersink 40°–60°

Consistent cutting performance through a wear-resistant coating

The insert’s PVD-coated AH3225 grade combines a hard coating with a tough carbide substrate to balance wear resistance and edge strength. This composition reduces flank wear and lowers the frequency of tool changes, which promotes a more predictable process and higher uptime in production runs. The coating supports a sharp cutting edge, making the component especially suitable where both edge integrity and process security are required; the result is stable metal removal and uniform tool life across batches.

Improved chip control and surface quality for reliable milling

A double-sided chipbreaker on the triangular insert provides controlled chip formation under varying cutting conditions, which helps to avoid long, stringy chips and reduces the risk of surface damage. With the insert’s 60° geometry and a corner radius of 0.8 mm, the cutting mechanics favour a good balance between robustness and finish quality — beneficial for shoulder and contour applications where consistent surface integrity is essential. The chipbreaker design also eases evacuation in both climb and conventional milling strategies.

Secure mounting and compatibility with Tungaloy milling bodies

The component is supplied with a cylindrical hole and a double-sided countersink (40°–60°) to guarantee secure clamping with the corresponding Tungaloy cutter bodies; correct seat geometry and fastening hardware must match to achieve rated performance. The insert thickness of 3.18 mm and triangular form ensure straightforward indexing, while the combination of hole and countersink contributes to repeatable seating and minimised runout. Note that insert, screw and shim dimensions must be verified against the host toolholder before assembly.

Application range and practical advantages on the shop floor

Engineered for a broad spectrum of milling tasks, the triangular indexable geometry suits planing, shoulder milling, slotting, high-feed and contour operations depending on the cutter family selected. The grade’s resistance to chipping supports interrupted cuts and variable engagement conditions, offering process reliability when a sharp edge and consistent results are required. For shop-floor teams, the insert reduces setup variability and contributes to stable cycle times when properly matched to cutter bodies.

FAQ

What materials is this insert suitable for?
The TNMU070308 AH3225 insert is a PVD-coated carbide grade designed primarily for robust milling applications where a sharp edge and process security are required; it performs well across a wide material range typical for milling, subject to toolholder and parameter selection.

How does the double-sided chipbreaker affect performance?
A double-sided chipbreaker provides controlled chip formation in both cutting directions, improving chip evacuation and reducing the likelihood of surface damage when using the TNMU070308 in face, shoulder or contour milling operations.

Is the insert compatible with all Tungaloy milling bodies?
Compatibility depends on matching the insert seat, geometry and clamping system: the TNMU070308 requires a Tungaloy-compatible seat designed for triangular inserts with a central hole and countersink. Ensure the cutter body specification corresponds to the insert dimensions before assembly.

What advantages does the AH3225 grade provide in interrupted cuts?
The AH3225 grade is formulated to resist chipping and maintain a sharp edge under varying engagement conditions, offering improved process reliability for interrupted cuts and where consistent edge integrity is necessary.

How is the insert indexed and secured?
Indexing is performed via the central cylindrical hole and countersink; correct fasteners and, if required, shims must be used to achieve repeatable seating and minimal runout with the corresponding milling body.
