TCMT110204-MK4 WKK20S turning insert (triangular 60°, Tiger·tec Silver) by Walter Tools

The TCMT110204-MK4 WKK20S is a triangular turning insert designed for productive machining of cast iron components, offering a balanced combination of wear resistance and reliable chip control for consistent process results

• Tiger·tec Silver coating for high wear resistance
• MK4 chipbreaker optimised for short chips
• 7° clearance angle for robust cutting action
• 0.4 mm nose radius for fine surface finishes

Increased productivity through optimised wear behaviour

The combination of a Tiger·tec Silver coating and a dedicated WKK20S grade reduces abrasive wear when machining cast iron, which translates into longer cutting edge life and fewer changeovers. The coating technology creates a thermal and tribological barrier that slows crater and flank wear; this means more stable cutting conditions and a higher usable cutting length per edge. For production-oriented workshops, this improvement in tool life yields a direct efficiency gain and helps maintain consistent cycle times across batches.

Reliable chip control and process security

Equipped with the MK4 chipbreaker, the insert delivers controlled, short chips that evacuate reliably in interrupted or continuous cutting of grey and nodular cast irons. The triangular 60° geometry provides three indexable cutting edges, increasing cost-efficiency per edge while ensuring secure clamping. The modest 7° clearance angle supports robust cutting without compromising edge strength, and the 0.4 mm nose radius is suitable for achieving improved surface quality on shafts and housings without excessive cutting forces. These features together support predictable results and reduce rework.

Practical application guidance and workshop benefits

The insert is tailored to the demands of cast-iron machining: it responds well to the typically abrasive chip conditions and the frequent short-chip formation found in such materials. As part of the Tiger·tec Silver series, the grade WKK20S offers a universal, tough performance class for jobs requiring a balance between wear resistance and fracture resistance. For engineers seeking process stability, the insert simplifies tooling decisions and supports standardised machining parameters across similar workpieces, contributing to fewer machine stops and a more efficient workflow.

FAQ

What materials is this insert intended for?
This insert is designed primarily for machining cast iron; the WKK20S grade and Tiger·tec Silver coating are tuned to resist abrasive wear typical of cast materials

How does the MK4 chipbreaker influence machining?
The MK4 chipbreaker produces short, controllable chips that improve evacuation and reduce the risk of entanglement during turning operations with cast iron workpieces

Can the insert be indexed to use all cutting edges?
Yes, the triangular 60° form provides three indexable edges, allowing efficient use of each insert before replacement
