SDMT120408-F57 WAK15 milling indexable insert (square 90°, 15° free angle) – Walter Tools

The SDMT120408-F57 WAK15 is a square milling insert designed for high-performance cutting of aluminium and other non‑ferrous metals, optimised for stable chip formation and long tool life in production milling.

• Square 90° geometry for precise milling
• 15° free angle for reduced rubbing
• Corner radius 0.8 mm for robust edge
• Chipbreaker F57 prevents material build-up

Faster, cleaner aluminium machining with targeted grade design

The WAK15 grade is an uncoated cemented carbide developed for non‑ferrous materials, notably aluminium, where sharp cutting edges and low adhesion are crucial. The insert’s geometry and the F57 chipbreaker promote effective chip control, reducing the risk of built‑up edge and minimising interruptions. For production environments aiming to maintain higher feed rates, this combination leads to improved surface finish and fewer tool changes, which enhances throughput without compromising dimensional accuracy.

Stable cutting edges for consistent production performance

A corner radius of 0.8 mm and a square 90° form provide mechanical support at the cutting edge, translating into repeatable cutting behaviour and predictable wear patterns. The 15° free angle reduces flank contact and friction, which helps to maintain edge integrity when machining softer, gummy alloys. These geometric choices lower the incidence of edge deformation and make the insert suitable for slotting and face milling operations where edge stability is required for consistent part quality.

Simple specification and integration into machining cycles

The insert is supplied in the well‑established Walter N‑series and carries the designation SDMT120408‑F57 WAK15, allowing straightforward selection for existing toolholders that accept square inserts. The size code 12 and thickness code 04 match common indexable systems, while the tolerance class M ensures compatibility with typical clamping and seating conditions. With its focus on chip formation and minimal adhesion, the component reduces cleaning intervals and supports continuous operation, contributing to lower overall cycle costs in aluminium processing.

FAQ

What materials is this insert suitable for?
The SDMT120408‑F57 WAK15 insert from Walter Tools is optimised for aluminium and other non‑ferrous metals, as indicated by the WAK15 grade and the insert’s chip control geometry.

How does the F57 chipbreaker benefit machining?
The F57 chipbreaker promotes controlled chip segmentation and reduced material adhesion, which improves surface finish and lowers the likelihood of built‑up edge when machining soft, sticky alloys.

Why select the WAK15 grade for aluminium work?
WAK15 is an uncoated cemented carbide grade developed for non‑ferrous applications; it provides sharp, wear‑resistant cutting edges and reliable performance in continuous milling of aluminium components.

What do the geometry codes mean for process stability?
The square 90° shape and 0.8 mm corner radius give mechanical support and repeatable cutting behaviour, while the 15° free angle reduces flank contact to help preserve edge life during milling.
