TPMT110204-MK4 WKK20S indexable turning insert – Tiger‑tec Silver for cast iron (Walter Tools)

A TPMT110204-MK4 WKK20S indexable turning insert optimised for efficient machining of cast iron under abrasive conditions, offering a robust chipbreaker and a triangle 60° form for multiple cutting edges

• Tiger‑tec Silver coating for wear resistance
• Optimised for cast iron (ISO K)
• Triangle 60° form, 0.4 mm corner radius
• MK4 chipbreaker for reliable chip control

Longer tool life through coated carbide technology

The combination of the WKK20S carbide grade and Tiger‑tec Silver technology provides significantly improved wear resistance when machining abrasive materials. Coated carbide reduces flank and crater wear, which translates into longer cutting edge life and fewer insert changes during production. For operations focused on steady throughput, this means more predictable tool replacement intervals and improved machine uptime, supporting higher overall productivity in series turning tasks.

Consistent chip control for safer, faster cycles

Equipped with the MK4 chipbreaker, the insert produces short, controllable chips suited to the breaking behaviour of cast materials. Controlled chip formation reduces the need for extensive manual chip clearing and lowers the risk of entanglement or surface damage. The chipbreaker design is particularly advantageous for interrupted cuts and varying feed rates, allowing a secure process window that supports faster cycle times without compromising component quality.

Robust geometry that balances strength and finish

The triangle 60° form offers three usable cutting edges per insert, providing economical indexability and quick edge changes. The 0.4 mm corner radius balances edge robustness with the ability to achieve a fine surface finish, making the insert suitable for both medium and finishing passes on cast iron. The moderate 11° relief angle supports stable engagement and reduces rubbing, which helps to maintain consistent dimensional accuracy across batches.

Tailored for cast‑iron applications and process reliability

Designed for ISO K materials, the grade is tuned to handle the abrasive nature and frequently short, brittle chips typical of cast iron. The insert’s properties—coated carbide grade WKK20S, the MK4 chipbreaker and the Tiger‑tec Silver series—combine to deliver a process‑oriented solution that emphasises economy, repeatability and reduced machine downtime. For customers seeking dependable turning performance on cast components, this insert provides a technically sound and production‑ready option.
