SNMA190616-RK7 WKK10S — indexable turning insert for cast iron, Tiger‑tec Silver (Walter Tools)

An SNMA190616-RK7 WKK10S indexable turning insert engineered for productive, repeatable machining of cast iron components with robust geometry for interrupted and continuous cuts

• Tiger‑tec Silver coated carbide for durability
• Optimised for cast iron (ISO K) machining
• Square 90° form with 1.6 mm corner radius
• RK7 chipbreaker tuned to short, breaking chips

Consistent chip control and extended tool life

The combination of the WKK10S cutting grade and the Tiger‑tec Silver coating delivers consistent performance when machining abrasive cast iron. The coated carbide substrate resists abrasive wear, which translates into fewer changeovers and longer tool life. The RK7 chipbreaker is specifically tuned to the short, brittle chips typical of cast iron, improving evacuation and helping to maintain steady cutting forces for greater process stability.

Robust geometry for heavy‑duty turning tasks

A square 90° insert geometry with a 1.6 mm corner radius provides a favourable balance between edge strength and dimensional control. The 0° (negative) relief angle contributes to a robust cutting edge that tolerates interrupted cuts and variable cutting depths, reducing the risk of edge chipping under shock loads. These characteristics make the insert suitable for both stable finishing passes and more demanding roughing operations on cast iron workpieces.

Process reliability and economical productivity

Tolerance class M and the coated carbide construction enable predictable wear behaviour and repeatable results in production environments. By reducing unplanned tool changes and delivering consistent surface finishes, this insert supports higher throughput and lower unit costs. The design emphasises functionality and ease of use in automated and manual turning centres alike, helping to keep machining cycles efficient and predictable.

Application fit and typical uses in workshop practice

Designed primarily for ISO group K materials, the insert is intended for cast iron components where abrasive wear and short chip forms are common. Typical applications include facing, profiling and light to medium roughing of cast parts where stable chip control and reliable edge life are priorities. The insert form and chipbreaker make it a practical choice for workshops prioritising uptime and consistent part quality.
