SDMW09T3AEN-A57 WKP35S milling indexable insert — Tiger‑tec Silver for steel and cast iron (Walter Tools)

The SDMW09T3AEN-A57 WKP35S is a square 90° milling insert with a 15° clearance angle, designed for productive machining of unalloyed and alloyed steels as well as cast iron applications.

• Tiger‑tec Silver coating for high process security
• Grade WKP35S — coated carbide for steel and cast iron
• Square 90° form with 15° clearance angle
• T3 thickness with A57 chipbreaker for stable chip control

Consistent chip control for efficient steel and cast‑iron machining

The combination of the WKP35S grade and the Tiger‑tec Silver series delivers a coating and substrate pairing engineered for chip formation in ISO groups P and K. The A57 chipbreaker is shaped to produce short, controllable chips when machining steel and cast iron, reducing the risk of built‑up edge and improving process stability. For workshops that require predictable tool behaviour, this insert offers repeatable chip breakage and less interruption for chip clearance, which supports higher effective cutting times and smoother tool exchanges.

Geometry engineered for surface quality and repeatability

A square 90° form with a 15° clearance angle and T3 thickness yields a robust cutting edge that resists deformation under intermittent and continuous cuts. The indexable design permits four usable edges per insert, improving economy per edge change while the tolerance class M ensures consistent seating in the tool holder. These geometric characteristics translate into better surface finishes and dimensional repeatability on the workpiece, particularly in general purpose milling operations and shoulder cuts where edge life and stability matter.

Coating and substrate benefits that cut operating costs

The coated carbide construction, typical of the Tiger‑tec Silver family, provides abrasion resistance and thermal stability during elevated cutting speeds. This leads to extended tool life, fewer insert changes and reduced downtime—advantages that convert directly into lower cost per part in production cycles. The insert’s suitability for both alloyed and unalloyed steels and for cast iron makes it a versatile choice for mixed‑material batches, enabling fewer tool variants on the shop floor and a leaner tooling inventory.

Practical application guidance and selection tips

This insert is suitable for a wide range of milling tasks from roughing to light finishing when matched with appropriate cutting data and tool holders. The A57 chipbreaker assists with short chips typical for cast materials, while the coating and grade combination is optimised for heat management in steel machining. For selection, pair the square 90° insert with a rigid holder and moderate depths of cut to exploit the insert’s stability; adjust feed and speed based on material group (ISO P/K) and machine capability. For customised recommendations or cutting parameters, technical advisors at Metav Werkzeuge can provide documented guidance and published starting values.

FAQ

What materials is this insert designed to machine?
The SDMW09T3AEN-A57 WKP35S insert is designed for steel (ISO group P) and cast iron (ISO group K), exploiting the WKP35S grade and Tiger‑tec Silver coating for those materials.

How does the A57 chipbreaker affect machining?
The A57 chipbreaker produces short, controllable chips that improve swarf evacuation and reduce the likelihood of chip entanglement, particularly beneficial when machining cast iron and interrupted cuts with this Walter Tools milling insert.

Can this insert be used for finishing passes?
Yes; with appropriate cutting parameters and a rigid tool holder the insert can be used for light finishing as well as for productive roughing operations.

How many edges are usable per insert and what tolerance class applies?
The square form provides four usable cutting edges per insert and the tolerance class is M, ensuring consistent fit and repeatability in the tool holder.

Is specialised coolant required when using this insert?
No specialised coolant is mandatory; coolant strategy should be selected based on material and machine capability. For guidance on coolant and speeds/feeds, refer to the technical data provided with the SDMW09T3AEN-A57 WKP35S or consult Metav Werkzeuge.
