SNMU 120620 AH3135 – Milling insert SNMU120620 for Fräsen by Tungaloy

A SNMU120620 AH3135 indexable milling insert for Tungaloy milling systems, engineered for face, shoulder, slot and high-feed milling where a sharp cutting edge and process security are essential.

• PVD-coated carbide for extended wear resistance
• Double-sided chipbreaker for versatile cutting
• Square 12 mm form with 6.35 mm thickness
• Cylindrical hole with countersink for secure clamping

Longer tool life through hard-wearing coating and substrate

The PVD-coated cemented carbide substrate delivers demonstrable durability in interrupted and continuous milling operations. The AH3135 grade is specified as a wear- and break-resistant compound, which supports a consistently sharp cutting edge and reduced edge chipping. For production environments seeking predictable tool life and fewer index cycles, this combination reduces downtime and helps maintain surface quality across runs.

Reliable chip control and flexible indexing for varied milling tasks

Equipped with a double-sided chipbreaker, the insert enables stable chip formation across a range of cutting conditions. The geometry is optimised for face and contour milling in compatible tool families, improving evacuation and reducing re-cutting of chips. As a consequence, machine loads remain steady and tool-change frequency is reduced, which supports throughput and process reliability on mixed-batch production.

Precise seating and secure clamping for process security

The insert features a cylindrical hole with double-sided countersink (40°–60°) that ensures reproducible clamping in Tungaloy milling bodies. The square 12 mm form and 6.35 mm thickness combine with a 0° relief to offer a robust seating surface; this reduces the risk of micro-movement under load and supports repeatable part tolerances. Correct matching of insert seat, geometry and cutter body is required for optimum performance.

Applications and operational benefits in one solution

Designed for a broad set of milling operations, the indexable plate is suitable where a sharp edge and process security are required rather than extensive material-specific claims. The 2 mm corner radius provides a balance between edge strength and achievable surface finish, while the 90° orientation supports shoulder and face milling tasks. Using this insert in a matching Tungaloy system simplifies logistics by standardising on a proven geometry and clamping method.

FAQ

What primary milling tasks is this insert intended for?
The SNMU120620 AH3135 is intended for face, shoulder, slot, high-feed and contour milling within compatible Tungaloy systems where a sharp cutting edge and process security are required.

What are the key dimensions of the insert?
The insert is a square 12 mm plate with a thickness of 6.35 mm and a corner radius of 2 mm; ISO designation 120620.

How is the insert clamped in the milling body?
Clamping uses the cylindrical hole with a double-sided countersink (40°–60°); secure seating depends on a matching Tungaloy milling body and correct screw/tolerancing.

Is the insert suitable for indexing on both sides?
Yes, the double-sided chipbreaker indicates the insert can be indexed to use both active faces, extending usable life per insert.

What substrate and coating are used on this insert?
The SNMU120620 AH3135 uses a PVD-coated cemented carbide substrate; the AH3135 grade is described as wear- and break-resistant for milling applications.
