BCMT160508R-K55 WSM35G milling insert — Walter Tools, Tiger·tec Gold for rostfreier Stahl and superalloys

A BCMT160508R-K55 WSM35G indexable milling insert engineered for heavy-duty machining of rostfreier Stahl and heat-resistant superalloys, offering robust chip control and stable cutting edges in continuous production environments.

• Tiger·tec Gold coating, WSM35G grade
• K55 chipbreaker for stable chip control
• 7° relief angle for secure cutting
• 0.8 mm corner radius for edge strength

High-performance grade for demanding materials

The WSM35G grade, built on Tiger·tec Gold coating technology, is a coated carbide designed to withstand the thermal and mechanical loads encountered when machining rostfreier Stahl and superalloys. Coated carbide combines a wear-resistant surface layer with a tough substrate: the coating reduces adhesion and thermal impact while the carbide core maintains fracture resistance. For production lines where consistent surface finish and predictable tool life matter, this grade reduces the risk of built-up edge and sudden tool failure, translating into fewer interruptions and improved process stability.

Geometry engineered for repeatable chip formation

The combination of the K55 chipbreaker and the Parallelogram 75° shape produces controlled chip segmentation and reliable evacuation under varying cutting conditions. The insert’s 7° relief angle helps maintain a stable cutting engagement while the 0.8 mm corner radius increases edge robustness against microchipping. Together, these geometric features support consistent dimensional results and reduce the frequency of insert changes, which benefits cycle time and downstream inspection effort.

Suited to rostfreier Stahl and high-temperature alloys

Classified for the ISO groups M and S, the insert is intended for rostfreie Stähle and heat-resistant superalloys or titanium, materials that are known for poor thermal conductivity and high work-hardening tendencies. The grade’s thermal resilience and edge stability provide safer machining of such alloys, improving process reliability. When paired with appropriate cutting data for the respective workpiece group, the insert helps achieve better surface quality with fewer rework operations.

Practical benefits: uptime, handling and productivity

As an indexable solution, this insert minimises downtime by allowing quick indexation or replacement without full-tool change. The use of a coated grade and a robust chipbreaker extends effective cutting life, lowering the frequency of machine stops and tooling interventions. Backed by the Walter Tools engineering standards, the insert contributes to a predictable production rhythm and reduces the total cost per component through sustained performance and fewer quality-related rejects.
