BCMT090308L-G55 WSP45G Fräswendeschneidplatte (milling insert) by Walter Tools — Tiger·tec Gold PVD, for milling steel and superalloys

The BCMT090308L-G55 WSP45G is an indexable milling insert engineered for demanding finishing and semi-finishing operations in steels, stainless steels and high-temperature alloys.

Tiger·tec Gold PVD coating Versatile for Steel, stainless steel and superalloys Parallelogram 75° geometry 0.8 mm corner radius for fine finishes

Durable coating that extends productive uptime

The Tiger·tec Gold PVD system used in this grade combines a tough, wear-resistant surface with balanced toughness, yielding consistent tool life in interrupted and continuous milling. The grade WSP45G is a PVD-coated carbide designed to manage typical heat build-up and chip behaviour encountered when machining group P (steel), M (stainless) and S (heat-resistant alloys and titanium). For workshops aiming to reduce tool changes and stabilise component quality, this coating delivers a measurable improvement in wear resistance and process stability. The technical advantage translates into fewer unscheduled stops and a steadier production flow.

Geometry engineered for stable cutting and good surface quality

The insert’s Parallelogram 75° shape and a clearance angle of 7° produce a positive cutting action with favourable cutting-force distribution, which helps preserve the cutting edge under varying loads. The 0.8 mm corner radius balances edge strength with the ability to produce fine surface finishes, making the insert suitable for both finishing passes and modest depth of cut operations. The available chipbreaker G55 supports controlled chip segmentation, reducing re-cutting and improving coolant access; this combination results in consistent component tolerances and improved downstream processing.

Application scope and practical guidance for integration

As a purpose-built indexable milling solution, this insert is intended for a wide range of milling tasks in modern machine shops, from profile milling to shoulder and face milling in medium to high-alloy materials. Compatibility with machining groups P, M and S means the insert can be standardised across mixed-production environments, simplifying tool management. For best results, pair the insert with a suitable toolholder that supports the parallelogram geometry and consult spindle speed and feed charts for the specific material group; Metav Werkzeuge can provide cutting parameter recommendations to suit machine rigidity and workpiece metallurgy.

FAQ

Which materials is the insert suited for? The BCMT090308L-G55 WSP45G is specified for machining steels, stainless steels and heat-resistant alloys (material groups P, M and S) and performs well where heat and tough chip formation are factors.

How does the Parallelogram 75° geometry affect cutting performance? The Parallelogram 75° form improves chip flow and reduces cutting forces in certain milling directions, helping to maintain a stable cutting edge and consistent surface finish with the BCMT090308L-G55 insert.

What is the purpose of the G55 chipbreaker? The G55 chipbreaker promotes controlled chip segmentation and evacuation, which reduces recutting and supports reproducible component tolerances when using this Walter Tools milling insert.

Can the insert be used for finishing and semi-finishing? Yes, the 0.8 mm corner radius and the positive geometry make the insert suitable for finishing and semi-finishing passes while balancing edge strength and surface quality.
