BCMT120420L-G55 WSP45G milling insert — Tiger·tec Gold, for steel / stainless steel / Superalloys (Walter Tools)

A BCMT120420L-G55 WSP45G is a parallelogram 75° milling insert with Tiger·tec Gold PVD coating designed for versatile milling of steel, stainless steel and heat‑resistant alloys such as titanium.

• Tiger·tec Gold PVD coating
• Suitable for P / M / S materials
• Parallelogram 75° geometry
• 7° clearance with 2 mm corner radius

Durable coating and grade for higher cutting speeds

The combination of Tiger·tec Gold and the WSP45G grade describes a PVD-coated carbide developed for demanding milling tasks. This coating increases thermal resistance and reduces flank wear, which in practice allows for elevated cutting speeds and longer tool life without compromising surface quality. Because the grade covers the material groups P / M / S, it is optimised for the heat generation and chip formation typical of steel, engineered for the adhesion-prone behaviour of stainless steel and robust enough for Superalloys and titanium. The result is a measurable gain in machining efficiency and fewer insert changes per shift.

Geometry and chip control that stabilise production

The parallelogram 75° form combined with the G55 chipbreaker provides a secure seat and a positive cutting approach that favours controlled chip flow. The modest 7° clearance reduces rubbing and minimises heat at the flank, while the 2 mm corner radius offers a compromise between edge strength and achievable surface finish. Together these features promote stable cutting edge behaviour during both interrupted cuts and continuous passes, reducing the risk of unexpected edge failure and supporting consistent part tolerances.

Practical application guidance for reliable results

This insert is suited to a range of milling tasks from medium‑roughing to finishing when robustness and reproducibility matter. The WSP45G sort is particularly effective where a balance between wear resistance and toughness is required; choose feeds and speeds according to machine rigidity and workpiece condition, and consider climb milling to enhance chip evacuation with the G55 breaker. For special alloys or unusually long runs, process trials and incremental optimisation are recommended to exploit the insert’s high productivity potential while preserving surface integrity.

FAQ

Which materials is this insert intended for?
The BCMT120420L-G55 WSP45G milling insert from Walter Tools is specified for the ISO groups P / M / S, meaning it machines steel, stainless steel and heat‑resistant Superalloys/titanium effectively.

What advantage does the Tiger·tec Gold coating provide?
Tiger·tec Gold is a PVD coating that increases thermal resistance and wear life; on the WSP45G grade it stabilises the cutting edge and enables higher cutting speeds with improved tool life.

How does the parallelogram 75° geometry affect machining?
The parallelogram 75° form gives a secure seat and positive cutting engagement, supporting stable chip flow and reducing the tendency for the insert to deflect under load.

Is the 2 mm corner radius suitable for finishing?
A 2 mm radius provides enhanced edge strength and is suitable for semi‑finishing and finishing where a balance between surface quality and edge durability is required; the G55 chipbreaker helps maintain consistent chip formation.
