TCMT110208-RK4 WKK10S indexable insert — triangle 60°, Tiger·tec Silver, Walter Tools

TCMT110208-RK4 WKK10S is a coated carbide triangle insert designed for turning and boring operations in cast iron applications, offering robust edge life and stable chip evacuation.

• TCMT110208-RK4 WKK10S – Tiger·tec Silver technology
• Triangle 60° form with 0.8 mm corner radius
• RK4 chipbreaker optimised for cast iron chips
• 7° relief angle for stable cutting engagement

Consistent chip control for abrasive cast iron work

The combination of the RK4 chipbreaker and the WKK10S grade addresses the characteristic short, brittle chips of cast iron by promoting predictable chip segmentation and evacuation. This yields a more stable cutting process, which in turn reduces the risk of built-up edge and unexpected interruptions. The insert’s design supports both interrupted and continuous cuts typical in finishing and light roughing, enabling a consistent process window even under varying workpiece geometries.

Coating and grade that extend cutting intervals

The Tiger·tec Silver coating technology provides a wear-resistant surface suited to the abrasive nature of grey and nodular cast irons. The WKK10S grade combines a coated carbide substrate with a coating structure that balances toughness and wear resistance, so edge life is extended without compromising dimensional repeatability. For operations where abrasive wear is the limiting factor, this combination offers measurable gains in productivity through fewer indexings and replacements.

Geometry engineered for strength and surface quality

A triangle 60° shape with a 0.8 mm corner radius delivers a favourable compromise between edge strength and surface finish: the larger radius increases resistance to mechanical and thermal shock, while the insert form allows multiple cutting edges per index. The 7° relief angle ensures secure seating and helps to control cutting forces, which supports steady tool engagement and consistent surface results on cast iron workpieces.

Practical selection and application advice

When choosing the insert for a specific turning or boring task, consider the interplay of feed, depth of cut and insert radius: the 0.8 mm corner radius is suited to medium finishing passes and light roughing where a balance of edge robustness and finish is required. The TCMT110208-RK4 WKK10S insert is particularly effective in operations with frequent interruptions or interrupted cuts because the grade tolerates the abrasive wear typical of cast iron.

FAQ

What materials is this insert designed for?
The TCMT110208-RK4 WKK10S is formulated for machining cast iron, with the WKK10S grade and Tiger·tec Silver coating optimised for abrasive wear typical of these materials.

How does the RK4 chipbreaker affect performance?
The RK4 chipbreaker controls and breaks brittle cast iron chips into manageable segments, improving evacuation and reducing the chance of chip entanglement during turning and boring.

What is the benefit of the 0.8 mm corner radius?
A 0.8 mm radius increases edge strength for stable engagement and improves resistance to mechanical shock while still allowing good surface finish on finishing passes.

Is this insert suitable for interrupted cuts?
Yes, the combination of the coated grade and the insert geometry makes the TCMT110208-RK4 WKK10S well suited to interrupted and mixed cutting conditions often encountered in cast iron machining.

Where can one obtain machining parameter guidance for this insert?
Application advice and recommended cutting data for the TCMT110208-RK4 WKK10S can be requested from Metav Werkzeuge or found in Walter Tools’ technical documentation for Tiger·tec Silver grades.
