TCMT110208-FK6 WKK20S turning/drilling indexable insert — Walter Tools, Tiger·tec Silver, for cast iron

TCMT110208-FK6 WKK20S is a triangle 60° indexable insert designed for turning and bore-enlargement operations in cast iron, combining a wear-resistant grade with a dedicated chipbreaker.

• Tiger·tec Silver coated grade WKK20S
• Optimised for cast iron (ISO group K)
• Triangle 60° insert form for versatile clamping
• 7° clearance angle, 0.8 mm corner radius

Consistent machining when abrasive wear is a concern

The Tiger·tec Silver grade WKK20S is a coated carbide formulation that resists the high abrasive wear typical of cast-iron machining. This characteristic reduces flank wear and extends effective cutting life, which in turn lowers tool-change frequency and supports more stable production cycles. Combined with the FK6 chipbreaker, the insert promotes predictable, short breaking chips that ease evacuation in interrupted cuts and reduce the risk of workpiece surface damage.

Geometry tailored for versatility and edge stability

The triangle 60° geometry and the 0.8 mm corner radius deliver a robust cutting edge for medium to heavy cuts, while the 7° clearance angle helps maintain low cutting forces and consistent surface finish. The compact 11 mm insert size offers good accessibility in tight toolholders and suited tool setups. These geometric choices focus on providing a balance between durability and the possibility to use multiple cutting edges per indexable insert, supporting cost-effective machining.

Process benefits: productivity, chip control and repeatability

Equipped with the FK6 chipbreaker, this insert is optimised for the short, brittle chips produced by cast iron, improving swarf handling and reducing secondary operations for chip cleaning. The grade’s toughness supports reliable edge retention across varying batch sizes, which improves reproducibility and lowers scrap rates. For operations prioritising throughput and minimal downtime, the combination of Tiger·tec Silver coating and the FK6 geometry provides measurable productivity advantages.

Practical selection and integration guidance for workshop use

The article designation TCMT110208-FK6 WKK20S fits standard ISO-indexable systems that accept triangle 60° inserts; it is intended primarily for cast iron applications (ISO group K). When integrating into an existing tool system, pair the insert with a rigid toolholder suited to triangle inserts and verify clamping torque to ensure secure seating. For complex mixes of materials or specialised cycle requirements, technical consultation from Metav Werkzeuge is recommended to match cutting data and coolant strategy to the tool’s strengths.

FAQ

Is this insert suitable for cast-iron turning?
The TCMT110208-FK6 WKK20S is specifically formulated for cast iron (ISO group K) and performs best on abrasive, brittle cast-iron materials thanks to the Tiger·tec Silver grade and FK6 chipbreaker.

What are the main advantages of the Tiger·tec Silver grade?
Tiger·tec Silver provides improved wear resistance and temperature stability, which for the WKK20S grade translates into longer tool life and more consistent edge behaviour when machining cast iron.

Can the insert be used for boring as well as turning?
Yes, the insert’s designation indicates suitability for turning and bore-enlargement operations; it fits toolholders that accept triangle 60° indexable inserts for both processes.

Which chip behaviour can be expected with the FK6 chipbreaker?
The FK6 chipbreaker promotes short, controlled chips typical for cast-iron machining, improving evacuation and reducing entanglement risks at the tool nose.
