BCMT120408R-G55 WSM35G milling insert – Walter Tools (Parallelogram 75°, for rostfreier Stahl and superalloys)

BCMT120408R-G55 WSM35G is a milling indexable insert designed for demanding material applications and secure chip control in finishing and medium-depth machining.

• Tiger·tec Gold coating technology
• Optimised for rostfreier Stahl and superalloys
• Parallelogram 75° geometry for axial stability
• G55 chipbreaker for reliable chip control

Proven grade and coating for tough materials

The WSM35G grade, part of the Tiger·tec Gold family, combines a coated cemented carbide substrate with a coating system engineered for heat resistance and edge stability. This results in stable chip formation and extended tool life when machining rostfreier Stahl and high-temperature alloys. Users obtain fewer unplanned interruptions thanks to improved wear behaviour, which translates into higher process efficiency and reproducible part quality. The engineered grade reduces the risk of built-up edge and supports consistent surface finish across batches.

Geometry that improves surface finish and repeatability

The Parallelogram 75° insert geometry and dedicated G55 chipbreaker are designed to guide chip flow and moderate cutting forces. The form supports a predictable cutting direction and helps maintain contact conditions across the tool path, which benefits surface integrity and dimensional repeatability. With a 0.8 mm corner radius and a 7° clearance angle, the insert balances edge strength with the ability to achieve fine finishes; this combination suits finishing passes on difficult alloys without sacrificing edge life.

Compatibility and process economy

The insert is specified for material groups S and M, reflecting suitability for superalloys and rostfreier Stahl respectively. Its construction supports higher cutting speeds and stable performance in series production, yielding lower overall tooling cost per part. The design eases integration into existing toolholders that accept BCMT-style inserts and helps maintain cycle-time targets. Technical data such as the grade and chipbreaker allow engineering teams to calculate machining parameters with greater confidence, improving first-pass yield and reducing rework.

Manufacturer reliability and application support

Walter Tools' product family emphasises process security and repeatable performance, with the current series tuned for challenging materials. The insert’s tolerance class M and the Tiger·tec Gold technology together provide a robust baseline for both manual setup and automated tool-change systems. For customers seeking parameter suggestions or cutting trials, Metav Werkzeuge can provide application guidance and support data to ensure the insert meets production demands while maintaining component quality.
