VCMT110308-RK4 WKK10S turning insert – Tiger·tec Silver, for cast iron (Walter Tools)

The VCMT110308-RK4 WKK10S is an indexable turning insert designed for efficient machining of cast iron, combining a coated carbide grade with a tailored chipbreaker and a compact rhombic geometry.

• Tiger·tec Silver coated carbide for durability
• Optimised RK4 chipbreaker for cast iron
• Rhombic 35° geometry for universal turning
• 0.8 mm corner radius for robust edge strength

Durable grade for abrasive cast iron turning

The cutting grade is WKK10S, part of the Tiger·tec Silver family, a coated carbide solution optimised for the abrasive wear and short, brittle chips typical of cast iron. This specification delivers enhanced resistance to flank and crater wear, which translates into longer tool life and fewer index changes. For production environments where uptime and repeatability matter, the combination of a wear-resistant coating and a carbide substrate enables consistent component quality and reduced tooling costs over extended runs.

Geometry and edge design that improve chip control

A rhombic 35° insert form together with the RK4 chipbreaker provides controlled fragmentation of cast-iron chips and reliable evacuation from the cutting zone. The moderate 35° approach angle balances cutting force and surface finish, while the 0.8 mm corner radius gives a stable cutting edge that tolerates interrupted cuts and modest feed variations. These design choices lower the risk of edge chipping and help maintain dimensional stability, particularly when turning sections with varied cross-sections or interrupted surfaces.

Practical compatibility and workshop benefits

The insert’s dimensions and tolerance class support straightforward integration into standard toolholders and clamping systems. With a compact inscribed circle and a practical thickness, this indexable insert suits many common turning applications in cast iron machining. Combined with Walter Tools’ quality control and predictable tolerance class M, the insert helps reduce setup time and supports reliable process repeatability on CNC lathes and turning centres. For operators who value predictable tool life and consistent surface quality, this cutting grade offers a pragmatic balance of performance and economy.

FAQ

What materials is this insert intended for?
The VCMT110308-RK4 WKK10S from Walter Tools is designed primarily for machining cast iron (ISO K), with the grade and chipbreaker tuned for abrasive ferritic and grey iron types.

How does the RK4 chipbreaker affect performance?
The RK4 chipbreaker on this insert promotes controlled chip fragmentation for cast iron, improving evacuation and reducing the risk of chip-related surface damage when using the VCMT110308-RK4 WKK10S.

Can this insert be used for finishing or roughing operations?
With a 0.8 mm corner radius and a rhombic 35° geometry, the insert suits general-purpose turning; selecting feeds and depths of cut will determine whether it is used for finishing or more aggressive material removal.

Is the Tiger·tec Silver coating beneficial for production runs?
Yes — the Tiger·tec Silver technology applied to the WKK10S grade enhances wear resistance and edge stability, supporting longer cycles between index changes and consistent performance in production.

What tolerance and fit can be expected?
The insert is supplied to tolerance class M, ensuring consistent seat fit and repeatable positioning in compatible toolholders.
