VBMT160406-FK6 WKK20S – Rhombic 35° turning insert for cast iron, Tiger‑tec Silver (Walter Tools)

The VBMT160406-FK6 WKK20S is a coated carbide turning insert designed for efficient machining of cast iron, featuring an FK6 chipbreaker and a rhombic 35° geometry to balance edge strength and cutting precision

• Tiger‑tec Silver coating for wear resistance
• Designed for cast iron machining
• Rhombic 35° geometry with 0.6 mm nose radius
• FK6 chipbreaker for controlled chip formation

Consistent dimensional accuracy and robust cutting edge

The combination of a rhombic 35° cutting geometry and a 0.6 mm nose radius delivers a reliable balance between finishing capability and edge strength. The positive geometry reduces cutting forces and promotes stable engagement, which supports repeatable part tolerances and lowers the risk of edge chipping. The specification of tolerance class M signals manufacturing precision, so toolholders and set-up procedures can be standardised without compromising component quality. This results in fewer interruptions and a more predictable production rhythm.

Controlled chips and improved surface results for cast iron

The tailored FK6 chipbreaker is optimised for the typical short, brittle chips of cast iron, directing fragments away from the cutting zone and reducing recutting. The grade WKK20S is a coated carbide formulation tuned for abrasive wear common in cast materials; this increases time between index changes and improves surface finish consistency. For operations with medium chip loads, the chip control reduces thermal spikes at the cutting edge, which benefits both tool life and part integrity.

Coating technology that extends productive cutting time

The insert uses Tiger‑tec Silver coating technology to reduce flank wear and enhance the resistance to abrasive particles present in cast iron. The coating promotes higher cutting speeds and steadier performance over longer cycles, which lowers the unit cost per component. A 5° clearance angle minimises rubbing while maintaining support behind the cutting edge, helping to preserve geometry under typical turning feeds and depths. This technical pairing supports uninterrupted batch production and predictable maintenance intervals.

Reliable integration into machining processes

The insert’s design and small footprint make it compatible with common holders and turning tool systems, simplifying integration into existing setups. The FK6 chipbreaker and coated grade reduce the need for frequent rework, while the plate thickness code and execution ensure secure clamping and stable cutting conditions. By standardising on this insert series, shops can achieve consistent cycle times and improved first-pass quality, contributing to a more efficient workflow and lower process variability.

FAQ

What materials is this insert suitable for?
The VBMT160406-FK6 WKK20S by Walter Tools is optimised for cast iron; the WKK20S grade and FK6 chipbreaker address the abrasive and brittle nature of these materials.

What benefit does the Tiger‑tec Silver coating provide?
Tiger‑tec Silver on the WKK20S grade reduces flank wear and increases resistance to abrasive particles, enabling higher cutting speeds and extended tool life for the VBMT160406-FK6 insert.

How does the FK6 chipbreaker affect machining?
The FK6 chipbreaker ensures controlled, short chips during cast iron turning, lowering the risk of recutting and improving surface quality when using the VBMT160406-FK6 WKK20S insert.

Is the rhombic 35° geometry suitable for finishing?
Yes; the rhombic 35° geometry with a 0.6 mm nose radius offers a good compromise between finishing ability and edge strength for repeatable surface results.

Which tolerance class and execution are specified for this insert?
This insert is manufactured to tolerance class M with execution code T, supporting consistent fit and reliable clamping in standard holders.
