RCMT1204M0-RK4 WKK10S — indexable turning insert, Tiger·tec Silver for cast iron (Walter Tools)

The RCMT1204M0-RK4 WKK10S is an indexable turning insert engineered for cast iron machining, combining a coated-carbide grade with a round geometry to deliver reliable chip control and extended edge life.

• Tiger·tec Silver coated carbide grade WKK10S
• Optimised for cast iron machining
• RK4 chipbreaker for stable chip control
• Round insert, size 12 with 7° clearance

Boosted process stability through coating and geometry

The combination of the Tiger·tec Silver technology and the WKK10S grade provides a coated carbide solution aimed at resisting abrasive wear common in cast iron workpieces. The coating reduces flank wear and helps to maintain a consistent cutting edge, which in turn supports repeatable results and longer tool life. By choosing a round geometry, the insert offers dependable edge strength and simple indexability, helping to reduce tool changes and maintain productive cycles.

Cleaner machining of cast iron with effective chip control

The RK4 chipbreaker is designed for the typical short, brittle chips produced when machining cast iron, promoting predictable breakage and safe evacuation from the cut. This feature reduces the likelihood of chip-related surface defects and minimises operator intervention. In practical terms, improved chip control contributes to lower scrap rates and fewer interruptions, which supports leaner production and better use of machine capacity.

Simple integration and handling for workshop efficiency

The round insert form and the specified 7° clearance make the component compatible with common clamping systems and stable in turning applications that demand robust edge security. Size designation 12 and thickness 04 align with standard tooling holders for turning operations. Technical teams value the clear match between insert geometry, chipbreaker and the coated grade because it simplifies tooling planning and helps to maintain consistent component quality across batches.

FAQ

Which materials is this insert intended for?
The RCMT1204M0-RK4 WKK10S is optimised for machining cast iron, with the grade and chipbreaker tuned for abrasive, short-chip behaviour typical of that material.

What does the designation WKK10S indicate?
WKK10S denotes a Walter Tools carbide grade within the Tiger·tec Silver coating family designed for wear resistance and broad applicability in cast iron turning.

How does the RK4 chipbreaker affect cutting performance?
The RK4 chipbreaker promotes short, consistent chips during turning, improving evacuation and reducing chip-related surface marks in cast iron machining.

Is the round geometry advantageous for interrupted cuts?
The round form increases edge strength and indexability, making it suitable where robustness and repeatable seating of the insert are required.
