TCMW110204-RK6 WKK20S indexable insert for cast iron machining – Walter Tools

TCMW110204-RK6 WKK20S is an indexable insert designed for machining cast iron components in drilling, boring and turning applications, offering a robust chip control system and a coating optimised for abrasive cast iron grades.

• Tiger·tec Silver coating for improved wear resistance
• Optimised for cast iron machining
• RK6 chipbreaker for controlled chip formation
• 60° triangular insert with 0.4 mm corner radius

Consistent chip control reduces downtime and extends edge life

The combination of the WKK20S coated carbide grade and the RK6 chipbreaker is tailored to the typical, often short and brittle chips produced when machining cast iron. This pairing reduces abrasive wear and supports stable chip formation, which in turn lowers the frequency of edge changes and machine stops. The coating technology contributes directly to longer tool life and consistent edge performance, making the insert a cost-effective choice for repetitive production where process stability is critical.

Geometry that balances strength and surface quality

A 60° triangular shape provides three usable cutting edges per insert, increasing economy of use while the 0.4 mm corner radius balances edge strength with achievable surface finish. The moderate 7° clearance angle promotes secure engagement in interrupted cuts and cast-iron slots, while the thickness designation supports a stable seating in the holder. These geometric choices mean fewer insert changes and predictable cutting behaviour under typical cast-iron cutting conditions.

Designed for reliable integration into indexable systems

The insert is supplied in the Tiger·tec Silver series and is compatible with standard indexable insert tooling concepts that accept the TCMW family designation. Its graded performance is focused on abrasive materials and applications demanding repeatable results rather than experimental high-speed optimisation. With a focus on process reliability and straightforward edge management, this insert suits production environments where consistent output and predictable tool life are priorities.

FAQ

Is this insert suitable for cast iron only?
The TCMW110204-RK6 WKK20S insert and its Tiger·tec Silver grade are specifically optimised for cast iron machining, addressing abrasive wear and the typical chip forms of that material.

How does the RK6 chipbreaker affect machining?
The RK6 chipbreaker on the TCMW110204-RK6 WKK20S promotes controlled chip formation for safer evacuation and reduced risk of built-up edge when cutting cast iron.

Can the triangular shape be rotated for extra edges?
The 60° triangular form of this insert provides multiple cutting edges; rotating the insert between changes helps extend the usable life of the indexable system.

What benefits does the Tiger·tec Silver coating deliver?
The Tiger·tec Silver coating on the TCMW110204-RK6 WKK20S improves resistance to abrasive wear common in cast-iron machining and supports consistent edge life.
