BCMT120408R-G55 WKP25S milling indexable insert — Tiger·tec Silver, G55 chipbreaker (Walter Tools)

The BCMT120408R-G55 WKP25S is a parallelogram 75° milling insert intended for versatile roughing and finishing operations in Stahl and Gusseisen.

• Tiger·tec Silver coated for long tool life
• Optimised G55 chipbreaker for secure chip control
• Parallelogram 75° geometry for flexible milling strategies
• 7° relief angle for reliable cutting engagement

Durable coating and carbide grade for extended productivity

The insert belongs to the Tiger·tec Silver series and is supplied in the WKP25S grade, a coated carbide developed for demanding milling tasks. This combination delivers improved resistance to abrasive wear and stable edge retention under continuous cutting conditions. The coating technology reduces friction and thermal load, which translates into longer tool life and fewer interruptions in the production flow. Such material and coating choices support consistent machining results and reduce the frequency of tool changeovers in serial operations.

Geometry and chip control that stabilise the cutting process

With a parallelogram 75° form and the G55 chipbreaker, the insert reliably manages chip formation and evacuation during both up- and down-milling. The chipbreaker design favours short, controlled chips when machining Gusseisen and promotes favourable chip flow for a wide range of Stahl grades. The specified 7° relief angle helps maintain stable cutting engagement and reduces rubbing on the flank face, improving surface finish and limiting heat generation at the cutting edge.

Small corner radius and robust profile for consistent edge life

A corner radius of 0.8 mm balances strength and edge sharpness, enabling productive roughing as well as acceptable finishing results without frequent edge damage. The insert thickness and format (size 12, thickness 04) provide mechanical stability in moderate to heavy-duty milling operations, while the M tolerance class ensures repeatable seating and indexing in standard toolholders. This design choice supports reproducible results across batches and helps maintain component tolerances in serial production.

Practical benefits for workshop and production environments

This milling insert is optimised for machining Stahl and Gusseisen, reducing cycle times through consistent material removal rates and reliable chip control. Fewer interruptions for tool changes and predictable edge life contribute to improved overall equipment effectiveness. For toolroom engineers and production planners, the grade and geometry provide an economical compromise between performance and life span, supporting both scheduled production and short-series flexibility.

FAQ

What materials can be machined with this insert?
The BCMT120408R-G55 WKP25S is designed for machining Stahl and Gusseisen, offering good wear resistance and chip control for both material groups.

Which chipbreaker is fitted and what is its benefit?
The insert features the G55 chipbreaker, which promotes controlled chip formation and evacuation to support reliable milling in a range of Stahl grades and cast-iron applications.

How does the Tiger·tec Silver series improve performance?
The Tiger·tec Silver coating reduces friction and thermal loading on the cutting edge, resulting in improved edge life and consistent machining performance with the WKP25S grade.

Is the corner radius suitable for finishing operations?
A 0.8 mm corner radius provides a compromise between edge strength and surface finish, allowing for productive roughing and acceptable finishing in many applications.
