SCMT120408 AH725 indexable milling insert for Fräsen — square 12 mm, 0.8 mm radius (Tungaloy)

The SCMT120408 AH725 is a PVD‑coated carbide indexable insert engineered for general milling tasks. It is intended for use in Tungaloy milling systems where insert seat, geometry and cutter body match technically, and is suited to machining steel and stainless steels in face, shoulder, slot, high‑feed and contour operations.

Stable machining with a universal, PVD‑coated carbide grade

The combination of a PVD coating and the AH725 substrate delivers a universal, fracture‑resistant grade tailored for variable material mixes and demanding process security. The coating reduces flank wear and improves resistance to built‑up edge formation, which translates into more consistent cycle times and fewer unscheduled tool changes. For shops working across mixed batches of low‑alloy and corrosion‑resistant materials, this grade provides a balanced compromise between wear resistance and toughness, supporting longer cutting intervals without sacrificing surface finish.

Geometry focused on chip control and versatile milling tasks

A square 12 mm profile with a 0.8 mm corner radius and a 90° included angle offers a robust geometry for planing, shoulder and slot milling where strength and edge stability are required. The insert features a single‑sided chipbreaker for directed chip flow, improving chip evacuation in moderate to heavy cuts. The insert is supplied with a cylindrical hole and single‑side countersink (40°–60°) to ensure secure clamping; correct seating and matching of the insert to the cutter body are essential to achieve repeatable cutting conditions and to prevent assembly‑related variances.

Efficient production through predictable tool life and system compatibility

Designed for use in complete milling systems, the insert forms part of a system assembly consisting of the cutter body, the indexable insert, a clamp screw and, where required, a shim. Matching geometry and seat form between insert and body is critical for achieving repeatable performance and maximising tool life. The grade performs particularly well with smaller‑diameter cutters and where high demands on process reliability exist, enabling consistent surface quality and reduced scrap rates. Clear identification (manufacturer article number and OEM SKU) supports traceability and reordering in production environments.
