TCMT110204-RK4 WKK10S triangle indexable insert for cast iron — Walter Tools

TCMT110204‑RK4 WKK10S offers a coated, carbide-based grade for productive cast iron turning and boring operations.

Tiger·tec Silver coating technology
Optimised for cast iron machining
Triangular 60° shape for stable indexing
0.4 mm corner radius for robust edge

Proven productivity and extended tool life with advanced grade

The Tiger·tec Silver coating combined with the WKK10S grade is designed specifically to address the abrasive wear typical of cast iron machining. The result is a balance of wear resistance and toughness that sustains cutting performance over longer tool life cycles. That enhanced durability reduces downtime for insert changes and supports higher effective material removal rates, contributing directly to improved process economy and predictable production output.

Geometry engineered for stability and repeatability

The triangular 60° plate form delivers three usable cutting corners per insert and a secure clamping footprint, improving indexing stability during interrupted cuts often encountered in roughing. The 7° clearance angle reduces rubbing while maintaining a positive cutting action, and the 0.4 mm corner radius provides a robust edge for medium-to-heavy depth cuts. Together with the RK4 chipbreaker, the geometry ensures controlled chip formation and evacuation, which is essential for safe, reproducible machining cycles.

Material compatibility and application focus

This indexable insert is tailored to the machinability profile of cast iron (ISO group K). The substrate and coating technology compensate for the typically short, brittle chips and high abrasive loading of grey and nodular cast iron. The WKK10S classification denotes a coated carbide variety optimised for this material family, offering reliable performance where standard grades would suffer accelerated flank and crater wear.

Integration into the machining process and handling

The designation TCMT110204‑RK4 corresponds to a common insert format that suits a wide range of turning holders and boring adapters built for triangular inserts. The standardised form enables fast replacement and straightforward tool setup, supporting consistent cycle times and reduced changeover complexity. The insert’s tolerance class M contributes to predictable seating and alignment in modern toolholders, enhancing reproducibility across shifts and machines.

Operational benefits and manufacturing outcomes

Adopting this insert in cast iron turning tasks can improve part quality and surface finish while lowering the frequency of tool changes. The combination of Tiger·tec Silver coating and the RK4 chipbreaker helps prevent edge chipping and supports steady state cutting, which is beneficial for both small-batch and continuous production environments. Walter Tools’ grade selection underlines a focus on process security and repeatable results in industrial machining contexts.

FAQ

Which materials is this insert suitable for?
The TCMT110204‑RK4 WKK10S indexable insert is specified for cast iron (ISO group K), reflecting the WKK10S grade and Tiger·tec Silver coating optimised for abrasive, brittle chips.

What advantages does the Tiger·tec Silver grade provide?
Tiger·tec Silver on the WKK10S grade improves wear resistance and thermal stability during continuous or heavy cast iron machining, enabling longer tool life and steadier performance.

How does the RK4 chipbreaker influence chip control?
The RK4 chipbreaker promotes controlled chip segmentation and reliable evacuation when turning cast iron, reducing the risk of entanglement and supporting consistent surface quality.

What is the significance of the triangular 60° form and 0.4 mm radius?
The triangular 60° format supplies three cutting edges per insert and a stable clamping interface, while the 0.4 mm corner radius balances edge strength with acceptable surface finish for medium-depth cuts.
