TPMW16T308-RK6 WKK20S – Turning insert, Tiger‑tec Silver, for cast iron (Walter Tools)

The TPMW16T308-RK6 WKK20S is a coated turning insert engineered for robust machining of cast iron, featuring a 60° triangle form and an RK6 chipbreaker for reliable short-chip formation.

• Tiger‑tec Silver coating for wear resistance
• Optimised for cast iron machining
• RK6 chipbreaker for short, controlled chips
• Triangle 60° geometry for versatile turning

Consistent performance on abrasive cast iron

The insert uses the WKK20S grade within the Tiger‑tec Silver series, a coated cemented carbide solution tuned for abrasive wear typical of cast iron workpieces. This grade balances hardness and toughness, which reduces flank and crater wear and extends machining intervals. The specification K confirms dedicated suitability for cast iron according to ISO groupings; as a result, the cutting edge delivers predictable wear behaviour, fewer unplanned tool changes and improved process repeatability in serial production scenarios.

Secure chip control and process stability

Chip management is achieved through the RK6 chipbreaker combined with a corner radius 0.8 mm, producing short, controllable chip segments that reduce entanglement and enhance surface quality. The triangle 60° form increases edge economy by offering three usable cutting edges per insert, making it a cost-efficient choice where indexable performance and stable clamping are required. Short-chip formation also lowers cycle-time variability and simplifies chip evacuation in automated turning centres.

Operational efficiency and economic gains

This turning solution supports continuous production by reducing downtime linked to tool wear and chip-related interruptions. The insert thickness designation T3 and the 16 mm inscribed size contribute to mechanical rigidity when seated in compatible triangular pockets, aiding dimensional stability under moderate to heavy interrupted cuts. Together, the coated grade and chipbreaker design translate into improved surface finish and reduced rework, supporting higher first-pass yields and lower unit machining costs for cast iron components.
