SCMT09T308-RK4 WKK10S square 90° turning insert for cast iron – Walter Tools

The SCMT09T308 WKK10S is a square 90° indexable insert designed for efficient turning and boring operations in cast iron, combining a Tiger‑tec Silver coated carbide grade with an RK4 chipbreaker for robust chip control.

• Tiger‑tec Silver coating for abrasive wear
• Optimised for machining cast iron
• RK4 chipbreaker for reliable chip control
• Square 90° form, 0.8 mm corner radius

Higher productivity for abrasive cast‑iron work

The combination of the Tiger‑tec Silver coating and the WKK10S carbide grade makes this insert particularly suited to abrasive cast‑iron applications. The coating reduces flank and crater wear under typical cast‑iron cutting conditions, which leads to longer tool life and fewer indexings. The RK4 chipbreaker is engineered to manage the short, brittle chips typical of cast iron, reducing the risk of built‑up edge and improving surface consistency; this translates directly into more stable cycle times on production parts.

Geometry that supports consistent part quality

A square 90° plate form paired with 7° clearance and a 0.8 mm corner radius gives a balance between strength and edge sharpness. The sturdy corner supports heavier cuts while the modest radius helps maintain acceptable surface finish without compromising edge life. The T3 plate thickness and tolerance class M contribute to repeatable clamping and indexing, so process engineers can rely on predictable tool offsets and maintain tight machining tolerances in series production.

Application guidance and process benefits

The insert is purpose‑built for cast‑iron turning and is a practical choice for both roughing cycles and general‑purpose finishing where abrasive wear is the dominant concern. With the specification optimised for G‑group materials, the design reduces downtime related to frequent insert changes. As an indexable insert from Walter Tools, it supports fast changeover and straightforward inventory management, helping shops to improve throughput and cost per part while maintaining surface quality and dimensional stability.

FAQ

What materials is this insert intended for?
The SCMT09T308-RK4 WKK10S is formulated for cast iron machining, with the Tiger‑tec Silver grade adapted to abrasive wear conditions typical of G‑group materials.

Which chipbreaker is fitted and what is its benefit?
The insert features an RK4 chipbreaker, designed to produce controlled, short chips in cast‑iron turning and to reduce the likelihood of edge build‑up.

How does the 0.8 mm corner radius affect machining?
A 0.8 mm corner radius provides a compromise between edge strength and surface finish, allowing moderate depths of cut while maintaining acceptable part quality.

Is the insert suitable for finishing as well as roughing?
Yes, the geometry and coated grade are suitable for general‑purpose use, offering productive roughing and stable finishing where abrasive wear is prevalent.

What series and coating technology does the insert use?
This product belongs to the Tiger‑tec Silver series and employs a coated carbide grade designated WKK10S for enhanced wear resistance.
