BCMT120408R-G55 WSP45G indexable milling insert — Tiger·tec Gold, for steel/stainless steel/superalloys (Walter Tools)

BCMT120408R-G55 WSP45G is an indexable milling insert engineered for versatile milling tasks, from productive roughing to precision finishing in steels, stainless steels and heat‑resistant alloys.

• Tiger·tec Gold PVD grade
• Suitable for steel, stainless steel, superalloys
• 0.8 mm corner radius for robust edges
• 7° relief angle for reduced rubbing

Proven grade for mixed-material production

The Tiger·tec Gold coating combines wear resistance with thermal stability, giving this PVD-coated carbide grade consistent performance in mixed‑material production. The chosen cutting grade is tailored to the thermal and tribological demands of machining steels and high-temperature alloys, so cycle times can be reduced while maintaining predictable tool life. The combination of a hard coating and a tough substrate ensures stable chip formation and repeatable results in both interrupted and continuous cuts.

Longer edge life with balanced geometry

A 0.8 mm corner radius strengthens the cutting edge against mechanical shock and flank wear without compromising achievable surface quality. The insert’s geometry supports efficient heat distribution and edge stability, which often means fewer tool changes and more uptime on the machine. The moderate radius is particularly effective where a compromise between roughing resilience and finishing capability is required, delivering measurable productivity gains in batch production.

Positive cutting behaviour for consistent process security

The insert’s 7° relief angle and parallelogram 75° shape promote a positive cutting action that reduces rubbing and minimises work hardening tendencies on stainless and heat‑resistant materials. This geometry supports controlled chip flow and helps maintain a sharp cutting edge under elevated temperatures. As a result, operators can expect improved process security and easier parameter transfer between jobs with similar material mixes.

Material range and application guidance

This grade is explicitly suited for machining steels (P), stainless steels (M) and heat‑resistant superalloys and titanium (S). The designation indicates a balanced composition aimed at resisting the high temperatures and adhesive tendencies of these materials while still providing reliable wear performance. Where unfamiliar with the specific cutting data, consult Metav Werkzeuge for feed and speed recommendations tailored to job size, machine rigidity and coolant strategy to achieve repeatable, economical results.

FAQ

What materials is this insert suitable for?
The BCMT120408R-G55 WSP45G insert is designed for machining steel, stainless steel and heat‑resistant superalloys/titanium, reflecting the P/M/S compatibility of the Tiger·tec Gold grade.

How does the Tiger·tec Gold coating influence tool life?
The Tiger·tec Gold PVD coating enhances wear resistance and thermal stability, which supports longer edge life and consistent performance across varied milling tasks.

When is a 0.8 mm corner radius recommended?
A 0.8 mm corner radius is recommended where a balance between edge strength for roughing and acceptable surface finish for semi‑finishing is required.

How does the parallelogram 75° shape affect cutting?
The parallelogram 75° geometry provides a positive cutting angle and controlled chip ejection, aiding process stability and repeatability in many milling operations.
