SCMT09T308-MK4 WKK10S — Indexable turning/boring insert for cast iron (Tiger‑tec Silver) | Walter Tools

The SCMT09T308-MK4 WKK10S is an indexable turning and boring insert engineered for productive cast‑iron machining, combining a Tiger‑tec Silver coating with an MK4 chipbreaker and a 0.8 mm corner radius for consistent surface finish and chip control

• Tiger‑tec Silver coated carbide grade
• Optimised for cast iron (K materials)
• MK4 chipbreaker for stable chip control
• 0.8 mm corner radius, 7° relief angle

Higher throughput from advanced coating technology

The Tiger‑tec Silver coating delivers a balance of wear resistance and thermal stability that translates directly into longer cutting edge life and fewer tool changes. For abrasive workpieces like cast iron, the WKK10S grade is formulated to resist abrasive wear and accommodate the often short, brittle chips typical of these materials. The result is improved process reliability and reduced downtime, which supports continuous production runs and predictable maintenance intervals.

Consistent chip formation and surface quality

The combination of the MK4 chipbreaker and a square 90° insert geometry provides controlled chip formation and evacuation in interrupted and continuous cuts. With a 0.8 mm corner radius and a 7° relief angle, the insert offers a robust cutting edge that helps maintain dimensional stability and surface finish. The insert geometry reduces the risk of built‑up edge and promotes regular chip breaking, which eases handling and minimises cycle interruptions on the shop floor.

Practical benefits for workshop integration

The insert thickness (T3) and compact 09 size make it suitable for a range of toolholders and tool‑post arrangements used in turning and boring operations. The grade’s focus on cast‑iron applications simplifies tooling decisions where abrasive wear and short chips dominate. Where process windows are tight, the coated grade and chipbreaker combination deliver a predictable compromise between productivity and tool life, enabling operations to plan inserts per component batch with confidence.

Application guidance and process advice

For optimal results in cast‑iron turning, select cutting parameters consistent with abrasive material behaviour: moderate cutting speeds and controlled feeds to exploit the WKK10S wear resistance while keeping cutting temperatures manageable. The insert’s design supports interrupted cuts and varying depths of cut; for unfamiliar setups, recommend a brief trial cut to establish the machine‑specific settings.
