SDGT 1204AF AH120 indexable milling insert for milling − Tungaloy

SDGT1204AF AH120 is a square indexable milling insert for Tungaloy milling systems, engineered for face, shoulder, slot, high-feed and contour milling where a sharp cutting edge and process security are required.

• PVD-coated carbide for high wear resistance
• Sharp cutting edge for process security
• Square 12 mm insert, 4.76 mm thickness
• Cylindrical hole with 40°–60° countersink

Optimised cutting performance for stable production

The AH120 grade is a PVD-coated carbide designed to provide wear- and chipping-resistant performance in milling operations. A sharp, stable cutting edge minimises unexpected edge breakdown and maintains consistent cutting forces, which in turn reduces vibrations and improves dimensional repeatability. For production planners this results in fewer unscheduled tool changes and a more predictable process window, supporting higher overall equipment effectiveness.

Secure clamping and mechanical compatibility for consistent results

This insert features a cylindrical hole with a single-sided countersink (40°–60°) and a 15° relief angle, which together ensure positive seating and reliable clamping in compatible tool holders. The system approach — comprising the milling body, insert, clamping screw and, where required, a shim — means that seat geometry and body design must match precisely. When mounted in the correct Tungaloy tool body, the insert’s design limits micro-movement at the cutting edge, enhancing process security and repeatability across batch runs.

Broad application range with controlled chip formation

The indexable square geometry (12 mm) and single-sided chipbreaker support a variety of milling tasks: planing, shoulder work, slotting, high-feed and contouring depending on the tool family selected. The combination of edge geometry and chipbreaking controls chip flow for stable evacuation and reduced heat concentration at the cutting zone. This typically improves surface finish and helps achieve uniform tool wear, which benefits both prototype shops and volume production environments.

Practical specification and operational advantages for workshops

With a compact 4.76 mm thickness and a zero corner radius, the insert integrates into standard Tungaloy milling families labelled for the SDGT form. The PVD coating enhances substrate protection and lowers adhesion tendencies on workpiece surfaces, extending effective tool life under intermittent loads. Spare-part management is simplified by standardised dimensions and the manufacturer SKU, enabling quick replenishment and minimal downtime when stocked through the supplier network.

FAQ

What materials is this insert suited for?
The SDGT 1204AF AH120 insert is a PVD-coated carbide grade intended for general milling tasks; material suitability depends on the selected tool family and cutting data, with the AH120 grade offering wear and chipping resistance for a wide material range.

How does the countersunk hole affect clamping?
A cylindrical hole with a 40°–60° countersink provides a secure mechanical seat in compatible Tungaloy holders, improving clamping stability and reducing the risk of insert movement during heavy milling.

Can this insert be used for high-feed milling?
Yes, the design allows application in high-feed operations when allocated to the appropriate tool body and cutting parameters within the SDGT series’ system compatibility.

What are the physical dimensions to consider for tool selection?
Key dimensions are a 12 mm square form, 4.76 mm thickness and a 15° relief angle; these must match the intended milling body and clamping setup.

Is the grade suitable where a sharp cutting edge is required?
The AH120 grade is specified for situations demanding a sharp edge combined with process security, offering a balance between edge integrity and wear resistance.
