SDMT120416-F57 WKP35S milling insert — square 90°, 1.6 mm radius, for steel and cast iron — Walter Tools

The SDMT120416-F57 WKP35S is a square 90° milling insert designed for high‑productivity machining of steel and cast iron with a Tiger·tec Silver coated carbide grade.

• Tiger·tec Silver coating technology
• Suited for steel and cast iron (P / K)
• Square 90° form with 1.6 mm radius
• 15° free cutting angle, chipbreaker F57

Consistent high productivity through advanced coating and grade

The combination of Tiger·tec Silver coating and the WKP35S grade provides a balanced defence against abrasive wear and thermal loads typical of turning and milling steels and cast irons. The coating reduces friction at the cutting edge and extends the usable life of the insert, which directly translates into fewer tool changes and higher uptime on the shop floor. Effective chip control via the F57 chipbreaker improves swarf management in interrupted cuts and mixed material batches, supporting stable cycle times and predictable process planning.

Geometry that improves surface quality and repeatability

A square 90° plate form with a 1.6 mm corner radius and a 15° free cutting angle delivers robust engagement and reliable edge support under varying cutting conditions. The geometry enhances load distribution at the cutting zone, reducing edge chipping and ensuring consistent component finish. With a tolerance class M, this insert offers repeatable dimensions for serial production, enabling close toolpath tolerances and dependable assembly fits. The solid, coated carbide construction provides dimensional stability through the life of the insert, which benefits both roughing passes and prestressed finishing operations.

Practical integration and process benefits for series machining

Specifically developed for the machining demands of steel (P) and cast iron (K), this insert fits standard square milling toolholders and is easy to index when an edge change is needed. The SDMT120416‑F57 WKP35S supports a broad range of cutting parameters, allowing process engineers to optimise feeds and speeds for either higher metal removal rates or finer surface appearance. Selecting this grade reduces the number of different inserts required across mixed production runs, which simplifies inventory and increases operational flexibility. In short, the insert helps secure stable cycle times and repeatable component quality across batch sizes.

FAQ

What materials is this insert suitable for?
The SDMT120416‑F57 WKP35S is specified for machining steel (P) and cast iron (K), reflecting the Tiger·tec Silver grade’s balance of wear resistance and toughness.

How does the F57 chipbreaker affect performance?
Chipbreaker F57 supports consistent chip formation and evacuation in mixed and interrupted cuts; the configuration reduces recutting and helps maintain surface quality with the WKP35S grade.

What benefit does the 1.6 mm corner radius provide?
A 1.6 mm corner radius increases edge strength for heavy engagement cuts and contributes to improved surface finish compared with smaller radii, while remaining suitable for common finishing passes.

Is the insert compatible with standard square milling toolholders?
Yes. The square 90° form and standard dimensions make it compatible with many indexable milling cutters designed for SDMT‑style inserts.

Why choose Tiger·tec Silver with the WKP35S grade?
Tiger·tec Silver coating combined with the WKP35S coated carbide grade offers a compromise of toughness and abrasion resistance, aimed at reducing downtime and providing consistent tool life in production environments.
