CNMG160612-RP5 WKK20S — indexable turning insert, Tiger·tec Silver for cast iron (Walter Tools)

CNMG160612-RP5 WKK20S is a rhombic 80° indexable turning insert for productive cast iron machining, featuring a 0° negative rake and the RP5 chipbreaker for controlled chip breaking.

• Tiger·tec Silver coating for wear resistance
• Optimised for cast iron (K) applications
• Rhombic 80° form, 1.2 mm corner radius
• Negative 0° rake for stable cutting

High productivity and predictable tool life for cast iron work

The combination of the Tiger·tec Silver technology and the WKK20S carbide grade is tailored to cast iron machining, focusing on abrasion resistance and coping with short, brittle chips. This results in a more predictable tool life and fewer unplanned stoppages on the shop floor. The coated substrate reduces flank wear under typical machining conditions, so production runs maintain dimensional consistency while reducing tool-change frequency and setup interruptions.

Consistent chip control and surface quality from proven geometry

The Rhombus 80° geometry with a 1.2 mm corner radius and the RP5 chipbreaker deliver stable chip formation and reliable evacuation during turning operations. The insert’s 0° (negative) relief angle supports robust cutting engagement and improved stability when heavy cuts or interrupted cuts are required. Together, these characteristics help to achieve repeatable surface finish and reduced risk of chatter on cast iron components, supporting efficient downstream processing.

Practical advantages at the toolholder level and application guidance

As an indexable turning solution from Walter Tools, this insert is suitable for standard CNMG toolholders and is coded for cast iron use (material group K). The design simplifies inventory management by providing a universal option for many cast-iron turning tasks, while the RP5 chipbreaker minimises secondary operations caused by uncontrolled chips. For process optimisation, consult Metav Werkzeuge’s application advice to select cutting parameters and holder geometry that match workpiece hardness and cycle demands.

FAQ

What materials is this insert intended for?
The CNMG160612-RP5 WKK20S insert is optimised for machining cast iron (material group K) and is designed to handle the abrasive wear and short, breaking chips typical of these materials.

How does the RP5 chipbreaker affect machining?
The RP5 chipbreaker on the CNMG160612-RP5 WKK20S improves chip control and evacuation during turning, reducing entanglement and supporting consistent surface finish on cast iron components.

Can this insert be used in conventional CNMG toolholders?
Yes, the CNMG160612-RP5 WKK20S conforms to standard CNMG dimensions and can be mounted in compatible indexable turning toolholders for typical lathe setups.

What are the main benefits of the Tiger·tec Silver technology?
Tiger·tec Silver coating on the WKK20S grade enhances wear resistance and helps maintain cutting-edge stability under abrasive conditions, contributing to longer, more reliable cutting cycles.
