CPGT060208-MK4 WKK20S indexable turning insert — Tiger·tec Silver for cast iron (Walter Tools)

CPGT060208-MK4 WKK20S is an indexable turning insert designed for machining cast iron with a focus on wear resistance and reliable chip control

• Tiger·tec Silver coating for long tool life
• Optimised for abrasive cast iron (K)
• MK4 chipbreaker for controlled chip formation
• Rhombic 80° geometry with 11° clearance

Extended tool life through optimised coating and grade

The combination of the Tiger·tec Silver coating and the WKK20S grade delivers improved abrasion resistance that extends service intervals under demanding cutting conditions. Coated carbide construction offers a hard, wear-resistant surface while retaining core toughness; this balance reduces flank wear and maintains cutting-edge integrity over longer runs. For operations focused on continuous productivity, the resulting durability contributes directly to lower tool-change frequency and more predictable production planning.

Predictable chip control and surface consistency

Built with an MK4 chipbreaker and a rhombic 80° shape, the insert promotes stable chip formation when turning cast iron, which is prone to short, brittle chips. The 0.8 mm nose radius, combined with the 11° clearance, supports consistent dimensional accuracy and a dependable surface finish in interrupted cuts and continuous profiles. These geometry choices make the insert well suited to typical cast-iron behaviours, helping to reduce secondary operations and rework.

Process reliability and application clarity for cast materials

Specified for ISO 513 group K (cast iron), this insert is tailored to abrasive materials that generate frequent, breaking chips; the WKK20S formulation is balanced for wear resistance and toughness in such contexts. The insert’s tolerance class G and standardised dimensions facilitate straightforward integration into established toolholding systems, enabling efficient stock replacement and minimised setup variation. For workshops seeking a robust, repeatable solution, the combination of coated carbide technology and an optimised chipbreaker delivers measurable benefits in cycle-time stability and part quality.

FAQ

What materials is this insert intended for?
The CPGT060208-MK4 WKK20S from Walter Tools is formulated for cast iron (ISO 513 group K), addressing the abrasive wear and short-chip behaviour typical of those materials.

How does the Tiger·tec Silver coating benefit performance?
The Tiger·tec Silver coating on the WKK20S grade improves abrasion resistance and extends tool life, making the insert suitable for longer production runs in abrasive cast-iron applications.

What role does the MK4 chipbreaker play in turning?
The MK4 chipbreaker ensures controlled chip formation and evacuation when cutting cast iron, supporting consistent surface quality and reducing the risk of chip-related interruptions.

Is the rhombic 80° geometry advantageous for interrupted cuts?
Yes, the rhombic 80° shape combined with the 11° clearance provides a robust geometry that helps maintain edge stability and dimensional accuracy in interrupted and continuous turning operations.

Which features support predictable part quality?
Key elements such as the 0.8 mm nose radius, coated carbide WKK20S grade and the MK4 chipbreaker contribute to repeatable surface finish and process stability when machining cast iron with the CPGT060208-MK4 WKK20S.
