Fräswendeschneidplatte SDMT120408-D57 WKP35G — Milling insert for steel and cast iron (Walter Tools)

A SDMT120408-D57 WKP35G milling insert engineered for high‑productivity machining of steel and cast iron, featuring the Tiger‑tec Gold coated grade for extended tool life and consistent results.

• Tiger‑tec Gold coated grade WKP35G
• D57 chipbreaker for stable chip control
• Square 90° insert with 0.8 mm corner radius
• Suitable for steel and cast iron machining

Maximise throughput with a high‑performance cutting grade

The coated carbide WKP35G grade within the Tiger‑tec Gold series is formulated for consistent performance when machining steel and cast iron, delivering a reliable balance between wear resistance and toughness. This results in reduced tool changes and stable cutting edges under typical milling temperatures, which directly supports higher machine utilisation and lower unit costs. The D57 chipbreaker is designed to shape chips predictably, improving evacuation and reducing the risk of recutting; the outcome is a smoother process window and fewer surface defects on workpieces.

Precision geometry that supports repeatable quality

With a square 90° plate form and a 0.8 mm corner radius, the geometry promotes a clear, defined cutting edge suited to medium‑duty finishing and semi‑finishing operations. The 15° relief angle contributes to effective cutting engagement while controlling contact stresses, which helps maintain dimensional accuracy over long runs. These geometrical choices, combined with the tolerance class M, provide predictable behaviour in multi‑pass operations and simplify toolpath planning for CNC milling systems, enabling consistent part quality and reduced inspection effort.

Robust chip control and operational reliability for demanding shops

The combination of Tiger‑tec Gold coating and the D57 chipbreaker supports stable chip formation across a range of steel grades and cast irons, reducing downtime associated with chip handling and tool wear. The insert’s thickness code 04 and compact 12 size suit modern cutter bodies that require reliable seating and minimal runout sensitivity. For manufacturing environments that demand process security and constant output, this insert offers a pragmatic balance of productivity and predictable life, making it a suitable choice for job shops and production lines alike. The SDMT120408‑D57 WKP35G demonstrates the advantages of coating technology paired with optimized geometry for everyday machining challenges.

FAQ

What materials is this insert suitable for?
The SDMT120408‑D57 WKP35G insert is designed for machining steel (ISO group P) and cast iron (ISO group K), utilising the Tiger‑tec Gold coated WKP35G grade for balanced wear resistance and toughness.

How does the D57 chipbreaker affect machining?
The D57 chipbreaker provides controlled chip formation and evacuation, improving process stability and reducing the likelihood of entangled chips when milling steel and cast iron with this Walter Tools insert.

What are the key geometry features that influence tool life?
The square 90° form, 0.8 mm corner radius and 15° relief angle combine to deliver a stable cutting edge, predictable wear progression and compatibility with standard cutter bodies for repeatable tool life.

Can this insert be used for finishing operations?
Yes. With its 0.8 mm corner radius and coated WKP35G grade, the insert is suitable for semi‑finishing and finishing passes where a combination of surface quality and tool life is required.

Is this a coated or uncoated insert?
The insert is supplied in the Tiger‑tec Gold series with the WKP35G coated carbide grade for enhanced wear resistance and process reliability.
