TNMU 120708 AH3225 indexable insert for milling by Tungaloy — PVD-coated carbide, 60° cutting angle

TNMU120708 AH3225 is an indexable insert designed for milling operations within a modular head system; it delivers process-stable cutting performance for shoulder, slot, face and contour milling depending on head geometry.

• Modular milling system compatibility
• PVD-coated carbide grade AH3225
• Triangular insert with 0.8 mm corner radius
• Countersunk hole and 60° relief angle

Process security from the PVD-coated carbide grade

The modular insert is furnished in PVD-coated carbide of grade AH3225, selected for a balance of wear resistance and edge strength. This combination promotes process security during interrupted cuts and mixed machining tasks: the coating reduces friction and heat build-up, while the substrate maintains dimensional stability. For production contexts where consistent cycle times and predictable tool life matter, the coated substrate reduces unplanned tool changes and supports steady throughput.

Geometry and chip control for predictable surface quality

A triangular insert form with a 0.8 mm corner radius and a 60° relief angle provides a defined engagement condition for milling edges and shoulders. The small corner radius allows controlled entry and exit of the cutting edge, reducing vibration and enhancing surface finish when finishing passes are required. The double-sided chipbreaker design manages chip formation on both usable faces, improving evacuation and reducing the risk of built-up edge; this translates into fewer reworks and more consistent component quality.

Modular system benefits and economical handling

Designed for the TungMeister modular concept, the insert suits heads with replaceable cutting modules and reusable shafts, so only the worn insert is replaced rather than the entire toolbody. This modularity lowers tooling investment per cutting length and simplifies inventory management. For job shops and production lines that switch frequently between part families, the quick-change characteristic shortens machine downtime and increases effective spindle utilisation, supporting a leaner production flow.

Application scope and operational advice

Optimised for conventional milling tasks, the insert is recommended where a sharp cutting edge and process reliability are priorities. Typical uses include shoulder milling, slotting, face milling and contouring depending on the chosen cutter head. The cylindrical hole with double-sided countersink (40°–60°) ensures secure, repeatable clamping in indexed holders. For best results, select cutting data that matches material hardness and toolpath strategy; the coated grade performs well under moderate to demanding cutting speeds while maintaining a stable edge.

FAQ

What milling tasks suit this insert best?
This insert is optimised for shoulder, slot, face and contour milling; the modular head selection determines the final application profile.

Which materials does the AH3225 grade handle reliably?
The AH3225 PVD-coated carbide is designed for applications that demand a sharp cutting edge and good wear resistance, delivering reliable performance across a wide range of common milling tasks.

Is the insert reversible and how many cutting edges are available?
The triangular, double-sided design provides multiple indexed cutting edges; the insert can be rotated to present a fresh edge, extending usable life per insert.

How is the insert secured in the cutter head?
The insert features a cylindrical hole with double-sided countersink (40°–60°) to ensure stable clamping and precise seating in compatible modular milling heads.

What effect does the 0.8 mm corner radius have on machining?
A 0.8 mm corner radius balances strength and edge sharpness: it reduces notch sensitivity when plunging and improves surface finish on finishing passes compared with larger radii.
