SNMU120612 AH3135 – Indexable milling insert for milling, PVD-coated carbide, 90° geometry (Tungaloy)

SNMU120612 AH3135 is a square indexable insert designed for use in Tungaloy milling systems, combining a sharp cutting edge with enhanced breakage resistance for reliable, productive milling operations.

• PVD-coated carbide for wear resistance
• Sharp cutting edge and process security
• Double-sided chipbreaker for versatile cutting
• Square form with 90° cutting angle
• Central hole with countersink for secure clamp

Extended tool life through high-performance coating

The PVD-coated carbide substrate delivers improved wear resistance and a consistently sharp edge, which together reduce downtime and tool changes. The coating on this insert is the AH3135 grade, optimised for milling applications where both a sharp cutting edge and process security are required. In practice, this means longer intervals between indexings and steadier surface finishes, with the coating helping to limit flank wear and microchipping under typical milling loads.

Secure seating and repeatable clamping for stable processes

Designed with a central hole and a cylindrical hole plus a double-sided countersink (40°–60°), the insert ensures secure clamping and repeatable positioning in compatible tool bodies. The square geometry and a plate thickness of 6.35 mm provide a rigid contact area that minimises movement under load, supporting consistent cutting forces and predictable tool life. Correct matching of insert seat, clamping screw and cutter body is essential to exploit these mechanical advantages.

Versatile geometry for multiple milling tasks

The square form with a 90° cutting angle and a 1.2 mm corner radius suits a range of milling operations, from face and shoulder milling to slotting and contouring depending on the associated tool family. The double-sided chipbreaker allows two usable cutting faces per side, improving economy and flexibility in the workshop. Such geometry helps reduce inventory complexity by providing a single insert solution for several machining tasks while maintaining reliable chip control.

Practical application guidance and performance expectations

As part of a matched Tungaloy milling system, this indexable insert is intended for productive, process-secure metalworking where a sharp edge and resistance to breakage are priorities. The insert’s construction supports stable chip formation and consistent cutting behaviour, which contributes to predictable component quality and reduced rework. For machine parameters, speeds and feeds should be selected according to the tool body family and material being machined to achieve the best balance between tool life and productivity.

FAQ

What milling operations are suitable for this insert?
This insert is suited to face, shoulder, slot, high‑feed and contour milling when used in the correct Tungaloy milling body and with matching geometry.

Which geometry and dimensions define the cutting behaviour?
The insert features a 90° cutting angle, 1.2 mm corner radius and 6.35 mm thickness, giving consistent cutting performance and rigidity for demanding milling tasks.

How is the insert clamped and how does that affect stability?
A central hole with a cylindrical bore and a double‑sided countersink (40°–60°) ensures secure clamping and repeatable seating when the cutter body and screw are matched to the insert form.

What is the coating and material of the insert?
The insert is made of PVD-coated carbide in the AH3135 grade, offering enhanced wear resistance and edge stability for milling applications requiring both sharpness and process security.

Can the insert be indexed to use multiple edges?
As a double-sided, square insert with a reversible design, it provides multiple usable edges, improving tool economy when correctly indexed in the compatible cutter body.
