Increase throughput with optimised chip control and coating

The combination of the Tiger·tec Silver coating and an engineered RK6 chipbreaker delivers measurable benefits in cast iron operations. The coating improves resistance to abrasive wear typical of grey and nodular cast irons, while the chipbreaker controls the frequently short, breaking chips produced by these materials. This results in steadier cutting forces, fewer interruptions for chip clearing and improved tool utilisation — factors that contribute directly to higher machine uptime and lower unit costs.

Consistent edge life and reliable surface quality

A 0.4 mm corner radius and the triangular 60° geometry provide a stable cutting edge that withstands the impacts and abrasiveness of cast iron. The geometry supports repeatable tool indexing and predictable wear patterns, which simplifies process planning and reduces scrap. With tolerance class M, the insert meets industrial repeatability expectations, allowing integration into serial production where consistent component surface quality matters.

Easy integration into existing turning operations

The insert’s familiar form factor and the clear ISO designation TPMW110204-RK6 WKK20S make tool change and inventory management straightforward. The design supports common clamping systems and toolholders for triangular inserts, enabling a fast transition from trial to series production. Its suitability for abrasive cast iron grades is indicated by the material code and the series assignment, making selection and application decisions more reliable for process engineers and shopfloor planners.

Practical machining considerations for cast iron

This grade is tuned to the abrasive wear and chip characteristics of cast iron: expect controlled chip formation and reduced tendency for built-up edge when cutting within recommended feeds. The RK6 chipbreaker is particularly effective at fragmenting chips, which reduces the need for manual intervention during long runs. Combined with the alloy and coating strategy, the insert offers a balance of toughness and wear resistance suitable for both intermittent and continuous cuts in cast iron components.

FAQ

What materials is this insert designed for?
The insert is designed primarily for cast iron applications; the WKK20S grade and Tiger·tec Silver series are optimised for abrasive wear and the short, breaking chips typical of cast iron.

How does the RK6 chipbreaker improve machining?
The RK6 chipbreaker provides controlled chip segmentation in cast iron turning, reducing chip-related interruptions and contributing to a steadier cutting process when using the TPMW110204-RK6 WKK20S insert.

What is the significance of the 0.4 mm corner radius?
A 0.4 mm corner radius offers a compromise between edge strength and surface finish, improving edge stability during interrupted cuts while maintaining acceptable component surface quality.

Is the insert compatible with standard triangular insert holders?
Yes, the triangular 60° form and ISO designation allow compatibility with standard holders that accept TPMW-format triangular inserts, simplifying tool changes and inventory handling.

Does the product include coating information?
The insert belongs to the Tiger·tec Silver coating technology, indicating a coated carbide design intended to enhance wear resistance in cast iron machining.
