Milling indexable insert BCMT090304R-K55 WSM35G — for stainless steels and superalloys — Walter Tools

The BCMT090304R-K55 WSM35G is a Tiger·tec Gold-coated milling insert designed for reliable machining of stainless steels and heat-resistant alloys in production environments.

*Tiger·tec Gold coating for high heat resistance *WSM35G grade for stainless steel machining *Parallelogram 75° shape for stable cutting *K55 chipbreaker for secure chip control

Consistent edge life when machining stainless and superalloys

The combination of the WSM35G coated carbide grade and the Tiger·tec Gold technology ensures improved heat resistance and a more stable cutting edge when machining demanding materials. The cutting material is optimised for the ISO groups M (stainless steels) and S (heat-resistant superalloys and titanium), which typically cause high temperatures and built-up edge formation. Using a coated grade that supports secure chip formation reduces tool wear and the need for frequent index changes, improving process reliability and lowering overall machining costs.

Controlled chip flow and reduced rework

The K55 chipbreaker is tailored to produce predictable chip shapes in long-chipping materials, which assists in evacuating swarf from the cut and reduces the risk of workpiece surface damage. The insert’s parallelogram 75° geometry changes the effective entry angle to favour stable cutting, while the 7° relief reduces rubbing on the flank and helps maintain cutting forces. The small 0.4 mm corner radius provides a balance between a defined cutting edge and a fine surface finish, making the insert suitable for operations where both edge robustness and finished part quality matter.

Practical fitment, repeatability and workshop benefits

The insert follows the established BCMT format and the plate dimensions (size 09, thickness 03) match common cutter bodies for straightforward replacement and minimal reworking of tool assemblies. The tolerance class M supports consistent seat fit and indexing accuracy, promoting repeatable cycle times and lowering setup effort. As a result, the insert is well suited for serial production and job-shop environments where predictable tool life, manageable stock levels and reduced machine downtime are priorities.

FAQ

What materials is this insert suitable for? This insert is specified for stainless steels (ISO group M) and for high-temperature alloys/titanium (ISO group S) according to the WSM35G grade and Tiger·tec Gold technology.

How does the K55 chipbreaker improve machining? The K55 chipbreaker on the BCMT090304R-K55 promotes controlled chip formation and evacuation, lowering the risk of surface damage and improving process stability during milling.

What does the parallelogram 75° shape mean for cutting? A parallelogram 75° geometry alters the effective entering angle to enhance cutting stability and reduce radial loads, which is beneficial for interrupted cuts and heavy engagement.

Can the insert be used in standard cutter bodies? The BCMT format and the specified plate size and thickness are compatible with common milling cutter bodies designed for this insert family; ensure the cutter seat matches the tolerance class M.

What benefit does the Tiger·tec Gold coating provide? The Tiger·tec Gold coating increases heat resistance and edge stability, extending edge life in demanding machining of stainless and heat-resistant materials.
