Increased throughput with optimised coating and grade

The combination of Tiger·tec Silver coating and the WKP25S carbide grade delivers a proven mix of wear resistance and toughness that supports longer tool life in serial production. Designed for the demands of steel and cast iron, the coating reduces abrasion and thermal wear while the grade maintains a strong cutting edge. This results in fewer indexings and lower downtime, which directly improves process efficiency and contributes to predictable production output.

Consistent chip control and edge security for stable results

Equipped with chipbreaker F57 and a negative 0° rake, the geometry promotes controlled chip formation under varying cutting conditions. The negative rake strengthens the cutting edge against impact and chipping, which is particularly beneficial for interrupted cuts or tougher cast materials. With tolerance class M the insert supports repeatable positioning in indexable holders, helping to maintain consistent surface quality and dimensional stability across batches.

Secure clamping and versatile milling performance

The square 90° insert form and corner radius 2 deliver a robust seating and cutting footprint, which aids in load distribution and resistance to edge breakdown. The standard size and thickness 05 combine stiffness with adaptability for a range of milling operations where stable engagement is required. The SNMX120520-F57 WKP25S insert is therefore suited to applications that prioritise reproducible performance and straightforward specification matching for mixed steel and cast-iron workloads.

FAQ

Which materials is this insert intended for?
The SNMX120520-F57 WKP25S insert is intended primarily for steel (P) and cast iron (K) applications, matching the designation of the grade.

What does the WKP25S grade mean?
WKP25S is a Walter Tools coated carbide grade within the Tiger·tec Silver technology, chosen to balance wear resistance and toughness for productive milling in steel and cast iron.

How does the negative 0° rake affect machining?
A negative 0° rake gives the insert a stronger cutting edge, reducing the risk of chipping under heavy or interrupted cuts and improving reliability in demanding operations.

What benefits does the chipbreaker F57 provide?
The chipbreaker F57 promotes consistent chip control and evacuation, which contributes to stable surface finishes and reduced risk of recutting chips in mixed-material production.

Is the square 90° form suitable for heavy milling?
The square 90° insert with a corner radius 2 provides a stable cutting geometry and good load distribution, making it suitable for robust milling tasks that require edge strength and repeatability.
