BCMT160508R-G55 WKP25S milling indexable insert – for steel and cast iron (Walter Tools)

The BCMT160508R-G55 WKP25S is a precision milling indexable insert engineered for productive machining of unalloyed and alloyed steels as well as cast iron, combining a wear-resistant grade with a chipbreaker tuned for controlled swarf formation.

• Tiger·tec Silver coating technology
• For steel (P) and cast iron (K)
• Parallelogram 75° geometry
• 7° clearance angle, 0.8 mm corner radius

Consistent edge life through advanced coating and grade

The insert uses the Tiger·tec Silver coating in the WKP25S grade, a coated carbide formulation developed to resist abrasive and thermal wear. Coated carbide means a hard base material with a thin, engineered surface layer that reduces friction and slows flank and crater wear, which translates into longer tool life and fewer insert changes during a shift. For production environments this grade delivers repeatable performance across batch runs, supporting predictable machining windows and efficient process planning.

Geometry and chip control that reduce rework and downtime

A parallelogram 75° shape with a dedicated G55 chipbreaker and a 0.8 mm corner radius provides a balance between strength and surface quality. The 75° approach angle lowers cutting forces for many milling setups, while the 7° clearance angle helps avoid rubbing and ensures clean entry and exit of the cutting edge. Together, these features improve swarf direction and reduce the risk of built-up edge or fractured chips, which helps to maintain part quality and reduce secondary operations.

Practical suitability and production benefits for P and K materials

Designed for the ISO groups P (steel) and K (cast iron), the insert suits a wide range of machining tasks where reliability and process security matter. The nominal insert size is 16 mm with a plate thickness of 0.5 mm, offering a compact yet robust cutting edge for common milling tools. Using this insert can simplify tooling inventories by covering multiple material groups with a single grade, and its balance of wear resistance and edge stability supports longer tool cycles and improved overall equipment effectiveness.

FAQ

Which materials can this insert machine effectively?
The BCMT160508R-G55 WKP25S milling indexable insert from Walter Tools is specified for ISO material groups P and K, making it suitable for a wide range of steels and cast irons.

What does the G55 chipbreaker do in practice?
The G55 chipbreaker on the BCMT160508R-G55 WKP25S controls chip form and evacuation, reducing the chance of long, stringy chips and improving surface finish and process stability.

Is the geometry suitable for finishing operations?
With a 0.8 mm corner radius and a 75° parallelogram geometry, the insert offers a compromise between strength and fine surface quality, allowing for medium to fine finishing strategies depending on machine and cutting parameters.

How does the Tiger·tec Silver coating benefit production runs?
The Tiger·tec Silver coating on the BCMT160508R-G55 WKP25S reduces wear and friction, extending edge life and supporting consistent performance across batch production, which contributes to lower downtime and predictable tool-change intervals.
