SNMU 120612 AH3225 indexable insert for milling (square, R1.2) — Tungaloy

The SNMU120612 AH3225 is an indexable insert for Tungaloy milling systems, engineered for face, shoulder, groove, high-feed and contour milling where a sharp cutting edge and reliable process security are essential.

• PVD-coated carbide AH3225
• Chipping- and wear-resistant grade
• Square 12 mm, R1.2 corner radius
• Double-sided chipbreaker
• Cylindrical hole with double countersink

Consistent performance from a wear-resistant PVD grade

The PVD-coated AH3225 grade delivers stable chip formation and a durable cutting edge suited to demanding milling operations. As a PVD-coated carbide insert, it combines a tough substrate with a hard, wear-resistant coating to reduce flank wear and delay edge breakdown, which leads to longer intervals between indexings and predictable cycle times. For production environments that prioritise uptime and repeatable results, this combination reduces rework and supports higher overall productivity.

Geometry and clamping designed for reliable machining

A square plate with a 1.2 mm corner radius and 90° included angle provides a balance between cutting strength and edge sharpness, making the insert suitable for general shoulder and contour milling. The double-sided chipbreaker controls chip flow on each cutting edge, helping to avoid built-up edge and to maintain surface quality. The insert is supplied with a cylindrical hole and double-sided countersink (40°–60°) to ensure secure clamping in compatible cutter bodies; correct seat and body matching are required to achieve rated performance.

System compatibility and typical applications

These indexable inserts are intended for use in matching Tungaloy milling systems and form part of a modular tool assembly consisting of cutter body, insert, clamp screw and, if needed, a shim. Typical operations include face, shoulder, slot, high-feed and contour milling depending on the assigned tool family. The insert’s combination of a sharp edge and process security makes it particularly suitable where consistent surface finish and edge integrity are required across batch production.

FAQ

What milling operations are suitable for this insert?
The SNMU120612 AH3225 indexable insert is intended for face, shoulder, slot, high-feed and contour milling within Tungaloy milling systems; the exact application depends on the assigned cutter family.

Which coating and substrate are used on this insert?
This insert uses the AH3225 specification: a PVD-coated carbide grade designed for wear and chipping resistance during milling.

How is the insert clamped and located in the cutter body?
The insert features a cylindrical hole with a double-sided countersink (40°–60°) and is secured by the cutter body’s clamping screw and any required shim; correct seat geometry and matching cutter body are essential.

How does the corner radius affect cutting performance?
The 1.2 mm corner radius provides greater edge strength than a smaller radius while maintaining a suitably sharp cutting profile for good surface finish and robust metal removal.

Is the insert reversible or indexable on both sides?
The plate has a double-sided chipbreaker and is designed to provide multiple usable cutting edges, enabling indexable reuse in compatible assemblies.
