BCMT120408R-K55 WSM35G fräswendeschneidplatte by Walter Tools — Tiger·tec Gold coated carbide, K55 chipbreaker

BCMT120408R-K55 WSM35G is a coated-carbide milling insert optimised for heavy-duty machining of stainless steels and heat-resistant superalloys, featuring a parallelogram 75° geometry for versatile milling strategies

• Tiger·tec Gold coating for thermal stability
• Optimised chip control K55 for secure chips
• Parallelogram 75° geometry for versatile milling
• Suitable for stainless steels and superalloys

Consistent performance in high-temperature materials

The combination of the WSM35G grade and Tiger·tec Gold coating delivers elevated thermal resistance and wear protection, which translates into longer tool life when machining stainless steels and superalloys. The coated-carbide substrate and multilayer surface treatment reduce diffusion and adhesion at the cutting zone, enabling more reliable tool behaviour under thermal load. As a result, process reliability improves and scrap risk is lowered, making the insert an effective choice for production environments that require repeatable outcomes.

Clean chip formation and secure cutting-edge stability

The integrated chip control K55 is engineered to break and evacuate chips reliably, supporting continuous cutting even on challenging alloys. Combined with the insert’s design, the chipbreaker promotes stable cutting conditions and helps maintain the integrity of the cutting edge over longer cycles. This leads to improved surface finishes with fewer interruptions for chip clearing and reduces the likelihood of built-up edge formation, which benefits throughput and reduces downtime for tool changes.

Geometry that supports flexible milling strategies

A parallelogram 75° insert form with a 7° clearance and a 0.8 mm nose radius offers a balance between robustness and precision. The geometry allows for different approach angles and positive engagement in a variety of milling operations, from light finishing passes to more aggressive roughing when toolpaths are adapted. The insert thickness and face proportioning support mechanical stability at the tool holder, assisting repeatability and dimensional control across batches.

Application scope and material suitability explained

This grade is assigned to material groups M and S, which correspond to stainless steels (M) and heat-resistant superalloys and Titan (S) under ISO classifications. The specification indicates that the insert is particularly suited to workpieces that develop high temperatures at the cutting zone and that demand a combination of thermal resistance and stable edge retention. For operations where consistent chip control and edge life are priorities, this insert provides a practical technical solution without overcomplicating tooling choices.

FAQ

Is this insert suitable for machining stainless steels?
Yes. The BCMT120408R-K55 WSM35G insert from Walter Tools is specified for material group M, indicating suitability for machining stainless steels under conditions that require thermal stability and secure chip formation.

Can the insert be used on heat-resistant superalloys and titanium?
Yes. The WSM35G grade and the Tiger·tec Gold coating are designed to handle the demands of material group S, which includes heat-resistant superalloys and Titan, offering improved wear resistance and edge life.

What advantage does the K55 chipbreaker provide?
The K55 chipbreaker promotes controlled chip formation and evacuation, reducing the risk of long, entangling chips and supporting stable machining cycles with better surface quality when using the BCMT120408R-K55 WSM35G.

Does the parallelogram 75° shape affect cutter compatibility?
The parallelogram 75° geometry provides a versatile cutting angle suited to a variety of milling applications; compatibility with cutter bodies depends on the specific toolholder system, but the insert form is standard for holders designed for 75° parallelogram inserts.

How does the 0.8 mm nose radius influence finish and stability?
A 0.8 mm nose radius balances robustness and surface finish capability: it increases edge strength for roughing while still supporting acceptable surface results in finishing passes when process parameters are controlled.
