BCMT120420R-G55 WSP45G — Milling insert, Tiger·tec Gold (Parallelogram 75°) by Walter Tools

The BCMT120420R-G55 WSP45G is a PVD-coated carbide milling insert designed for universal milling tasks on steels, stainless steels and heat-resistant alloys, combining edge stability with versatile geometry.

• Tiger·tec Gold PVD coating for edge stability
• Suitable for steel, stainless steel and superalloys
• Parallelogram 75° geometry for versatile milling
• 7° clearance and 2 mm corner radius for robust cutting

Higher throughput through stable edge performance

The combination of Tiger·tec Gold coating and a WSP45G PVD carbide substrate gives the insert consistent wear resistance and reliable cutting-edge behaviour. This translates into longer in-process time and fewer insert changes, supporting higher throughput on series and batch milling operations. The insert’s geometry promotes stable chip formation and reduced cutting forces, which in turn lowers machine load and contributes to predictable cycle times.

Broad material capability with predictable machining behaviour

Classified for the ISO groups P / M / S, the insert is balanced to manage thermal loads and chip formation across unalloyed and alloyed steel, stainless steel and heat-resistant superalloys or titanium. The G55 chipbreaker and Parallelogram 75° shape enable consistent chip control during shoulder milling and general face milling, reducing the risk of built-up edge on tough materials and improving surface finish. Technical terms such as P (steel), M (stainless) and S (superalloys/titanium) denote the intended workpiece families and indicate how the grade handles typical cutting challenges.

Geometry and dimensions that aid flexibility and process security

The insert’s 7° clearance and 2 mm corner radius support robust engagement at moderate depths, while the parallelogram 75° form allows versatile toolpath planning and stable side cutting. The thickness code 04 and plate size 12 (as specified) are compatible with a range of cutter bodies, enabling straightforward integration into existing tooling systems. These dimensional choices reduce chatter susceptibility and contribute to reproducible results across tool changes.

Practical benefits and application guidance

By using a grade optimised for toughness and temperature resistance, the insert achieves repeatable performance in mixed-material production runs and in demanding finishing steps. The focus on edge stability and chip control reduces the frequency of rework and supports consistent part quality, which is particularly relevant for job shops and in-process production lines aiming for uptime and low scrap rates.

FAQ

Which workpiece materials are suitable for this insert?
The BCMT120420R-G55 WSP45G is specified for ISO groups P, M and S, making it suitable for steel, stainless steel and heat-resistant superalloys or titanium with machining strategies adapted to each group.

What are the main advantages of the Tiger·tec Gold coating?
The Tiger·tec Gold coating on this grade enhances edge stability and wear resistance, which typically extends tool life and supports consistent surface quality under higher cutting temperatures.

For which milling operations is the parallelogram 75° geometry recommended?
The parallelogram 75° form is versatile for face and shoulder milling, offering straightforward entry angles and good chip evacuation in intermittent and continuous cuts.

How do the 7° clearance and 2 mm corner radius affect performance?
The 7° clearance reduces rubbing on the flank face while the 2 mm corner radius increases robustness at the cutting edge, improving resistance to edge chipping during roughing and semi-finishing passes.

Is this insert appropriate for mixed-production environments?
Yes; the WSP45G grade’s balance of toughness and temperature resistance supports reproducible performance across different material families, making it suitable for mixed-production runs.
