WNMG080412-RP5 WKK10S trigon 80° turning insert, Tiger·tec Silver by Walter Tools

The WNMG080412-RP5 WKK10S is a trigon 80° turning insert designed for productive machining of cast iron with a negative 0° rake and RP5 chipbreaker

• Tiger·tec Silver coating
• Optimised for cast iron
• RP5 chipbreaker for short chips
• Trigon 80° with 1.2 mm radius

Maximise productivity in cast-iron turning

The Tiger·tec Silver grade WKK10S combines a coated carbide substrate with a coating technology tuned for abrasive cast-iron work. This results in improved wear resistance and extended tool life, which in turn reduces downtime for insert changes and tool management. The RP5 chipbreaker is developed to promote short, manageable chips in brittle materials, lowering the risk of chip entanglement and contributing to a more predictable machining cycle. For production environments, this balance of wear control and chip form increases machining stability and repeatability.

Consistent surface quality with stable cutting geometry

A trigon 80° geometry offers a robust cutting edge and stable engagement in interrupted or continuous cuts. The 1.2 mm corner radius provides a compromise between edge strength and achievable surface finish, enabling consistent results across batches. The negative 0° rake increases edge robustness when facing tough cutting conditions typical of cast iron, while the plate form minimises vibration at the cutting zone. These characteristics together reduce scrap rates and improve the finished component’s dimensional conformity.

Practical advantages for shop-floor implementation

The insert’s specification and tolerance class M make it suitable for standard turning toolholders and indexable tooling systems, simplifying inventory and holder compatibility. The coded designation signals the exact chipbreaker, geometry and grade, which helps maintenance teams and buyers to standardise consumables. Where short chips and predictable tool life are priorities, the RP5-equipped trigon insert reduces manual chip handling and supports safer, uninterrupted operation in busy workshops.

Application guidance and material fit

This grade is engineered for the demands of cast iron; abrasive wear and short, breaking chips are typical characteristics of such materials and have been considered in the coating and chipbreaker design. The insert is therefore particularly suitable for grey and nodular cast irons where consistent chip control and edge life are required. When specifying cutting data, favour moderate cutting speeds and adequate coolant or chip evacuation strategies to preserve the coating’s performance and to sustain machining efficiency.
