TCMT090204-MK4 WKK10S – Boring/turning indexable insert, Tiger‑tec Silver grade for cast iron by Walter Tools

TCMT090204-MK4 WKK10S is a triangular indexable insert engineered for productive machining of cast iron in boring and turning applications

• Tiger‑tec Silver coating for wear resistance
• Optimised for cast iron machining
• 60° triangular insert with 0.4 mm nose
• MK4 chipbreaker for controlled chips

Reliable performance for abrasive cast‑iron work

The WKK10S grade, applied within the Tiger‑tec Silver series, is formulated as a coated carbide solution for abrasive cast‑iron materials. Its combination of coating technology and substrate composition improves wear resistance and reduces flank wear under typical cast‑iron cutting conditions. The MK4 chipbreaker is designed to produce short, manageable chips when machining brittle, abrasive workpieces, which supports uninterrupted production cycles and reduces the risk of chip-related interruptions. This results in clearer process windows and a more predictable tool life, enhancing manufacturing throughput.

Geometry tuned for consistent surface quality and edge stability

The triangular 60° format with a 0.4 mm corner radius balances edge strength and surface finish, making the insert suitable for general turning and boring where moderate radii are required. A 7° clearance angle helps to reduce rubbing while maintaining a stable cutting edge, and the compact insert thickness supports secure clamping in standard toolholders. Together, these features provide repeatable contact conditions at the cutting zone, which contributes to uniform component finishes and reduces rework in serial production.

Practical benefits that support productivity and process reliability

Using this insert simplifies tool management in cast‑iron operations: the standard TCMT designation fits common insert toolholders, while the MK4 chip control reduces the need for special chip evacuation measures. The Tiger‑tec Silver coating assists in extending tool life, lowering the frequency of tool changes and the associated downtime. For production environments prioritising consistency, the insert delivers predictable wear behaviour and ease of replacement, helping to keep cycle times stable and overall machining costs down.

FAQ

Which materials is this insert suitable for? The TCMT090204-MK4 WKK10S insert is optimised for machining cast iron; the WKK10S grade and Tiger‑tec Silver coating address the abrasive wear and brittle chip forms typical for these materials.

What advantage does the Tiger‑tec Silver coating provide? Tiger‑tec Silver improves wear resistance and thermal stability of the coated carbide substrate, which in the TCMT090204-MK4 WKK10S leads to more consistent tool life and reduced flank wear during cast‑iron production runs.

For which operations is the MK4 chipbreaker best suited? The MK4 chipbreaker on this triangular insert is engineered to produce short, controlled chips in brittle, abrasive materials, making it well suited to both boring and turning tasks where chip control is essential.

How does the 0.4 mm nose radius affect the result? A 0.4 mm nose radius provides a compromise between edge strength and surface finish; it supports durable cutting edges for heavier feeds while still enabling acceptable component finishes in general machining of cast iron.
