VCMT160412-RK4 WKK10S turning indexable insert – Tiger·tec Silver, RK4 for cast iron (Walter Tools)

The VCMT160412-RK4 WKK10S is a rhombic 35° turning indexable insert engineered for efficient and stable machining of cast iron, offering a coated carbide grade tailored to abrasive, short-chip conditions.

• Tiger·tec Silver coating for wear resistance
• Optimised RK4 chipbreaker for cast iron chips
• Rhombic 35° geometry for stable turning
• 1.2 mm corner radius for robust edge life

Achieve consistent productivity with wear-resistant cutting grade

The insert’s WKK10S grade, part of the Tiger·tec Silver series, provides a coated carbide construction optimised for the abrasive nature of cast iron. This means the grade resists flank and crater wear while maintaining cutting-edge integrity over extended cycles, which in turn reduces tool change frequency and supports uninterrupted production. The result is a measurable improvement in process reliability and machining economy for series turning and semi-finishing operations.

Reliable chip control and secure cutting behaviour in cast materials

The RK4 chipbreaker is designed specifically to handle the frequently short and brittle chips typical of cast iron; it promotes controlled fragmentation and evacuation, lowering the risk of chip build-up and surface damage. Combined with the rhombic 35° insert geometry, the system provides predictable cutting forces and stable contact conditions, which help to preserve machine spindle life and improve surface quality during steady cutting regimes.

Geometry and edge strength for repeatable tool life

With a 1.2 mm corner radius and a proven plate form, the insert delivers a robust cutting edge that tolerates intermittent impact and variable feed conditions. The tolerance class M supports consistent fit and interchangeability in standard tool holders, ensuring repeatable clamping and dimensional stability. These design choices translate into fewer stoppages and a dependable edge life that aids planning and reduces unplanned downtime.

FAQ

What materials is this insert suited for?
The VCMT160412-RK4 WKK10S insert is intended for machining cast iron and is optimised for abrasive, short-chip behaviour typical of that material.

How does the Tiger·tec Silver coating benefit production?
The Tiger·tec Silver coating on the WKK10S grade improves wear resistance and edge stability, extending service life and helping to maintain consistent part quality under industrial loads.

Is the RK4 chipbreaker suitable for finishing cuts?
The RK4 chipbreaker is designed for controlled chip formation in cast iron and performs well across roughing to semi-finishing ranges; cutting parameters should be adjusted according to the required surface finish.

Can this insert be used in standard tool holders?
Yes, the insert’s dimensions and tolerance class M are compatible with common tool holders designed for VCMT-style plates, enabling straightforward interchangeability.
