ADMT120408R-F56 WKP35S milling indexable insert – F56 chipbreaker, parallelogram 85° (Walter Tools)

The ADMT120408R-F56 WKP35S is a high‑performance milling insert designed for machining Stahl and cast iron in a range of milling operations

Tiger‑tec Silver coated carbide grade WKP35S
Optimised for Stahl and cast iron machining
Parallelogram 85° insert geometry
F56 chipbreaker for consistent chip control

Boosted productivity with consistent chip control

The Tiger‑tec Silver coating combined with the WKP35S grade delivers a balanced mix of wear resistance and toughness, which translates into longer tool life and fewer index changes on the shop floor. The F56 chipbreaker is engineered for reliable chip segmentation in mixed cutting conditions, reducing recutting and minimising downtime for chip clearing. With a stable cutting edge and the parallelogram form, the insert provides predictable cutting behaviour in interrupted and continuous milling, helping to keep cycle times steady and quality consistent. This makes the insert especially suitable where repeatability and process stability are priorities.

Machining capability tailored to Stahl and cast iron

The insert is specified for machining the ISO groups P and K, meaning it handles unalloyed and alloyed Stahl as well as cast iron. The grade is adapted to the typical heat generation and chip formation of these materials: it offers abrasion resistance for the abrasive nature of cast iron while maintaining edge stability for Stahl applications. The geometry and chipbreaker promote short, controlled chips when working cast components and allow efficient heat dispersion during aggressive cuts in Stahl. Users benefit from fewer surface defects and a reduced need for secondary finishing operations.

Geometry and cutting data that support process reliability

A clearance angle of 15° and a corner radius of 0.8 mm create a cutting edge that balances robustness with surface quality. The parallelogram 85° form ensures correct cutting edge orientation for axial and radial forces common in face and shoulder milling. The insert’s tolerance class M reflects manufacturing accuracy for consistent seating and repeatable results in standard tool holders. For applications requiring a combination of roughing and finishing, the moderate corner radius improves edge strength under load while still permitting acceptable surface finishes.

FAQ

What materials is this insert suited for?
The ADMT120408R-F56 WKP35S insert is designed for machining Stahl (ISO group P) and cast iron (ISO group K), offering wear resistance for abrasive cast materials and edge stability for Stahl.

How does the F56 chipbreaker influence machining?
The F56 chipbreaker promotes consistent chip segmentation and evacuation, reducing recutting and supporting stable cutting forces during both roughing and finishing passes with the ADMT120408R-F56 WKP35S.

What does the 0.8 mm corner radius mean for surface finish?
A 0.8 mm corner radius provides a compromise between edge strength and surface quality: it improves tool durability under load while still allowing acceptable surface finishes for many general milling operations.

Is the insert suitable for interrupted cuts?
Yes, the parallelogram 85° geometry and the coated WKP35S grade are engineered to withstand interrupted cutting conditions and maintain edge security during engagement.

How does the 15° clearance angle affect cutting behaviour?
The 15° clearance angle reduces rubbing and allows a positive cutting action that helps manage cutting temperatures and extend edge life, especially in mixed-material operations.
