TCMT16T304-MK4 WKK10S turning insert — Triangle 60°, for cast iron | Walter Tools

The TCMT16T304-MK4 WKK10S is a triangular 60° indexable turning insert designed for productive machining of cast iron, offering a stable cutting edge and controlled chip formation for series production environments

• Tiger·tec Silver coating for extended tool life
• WKK10S grade optimised for cast iron
• MK4 chipbreaker for controlled chip formation
• Triangle 60° shape with 0.4 mm corner radius

Boosted productivity for cast iron turning

The combination of Tiger·tec Silver coating and the WKK10S coated-carbide grade is engineered to resist the abrasive wear typical of cast iron machining, so tool changes and unexpected stops are reduced. The MK4 chipbreaker promotes predictable, short chips that evacuate reliably, lowering the risk of workpiece damage and machine downtime. This results in a measurable increase in process efficiency and a more consistent cycle time for lot production, making the insert particularly suitable for workshops and small series manufacturing where uptime is essential.

Consistent surface finish through stable geometry

A triangle 60° insert geometry with a 0.4 mm corner radius and a 7° relief angle delivers repeatable cutting conditions and stable tool positioning. The nominal T3 thickness provides rigidity for interrupted cuts and facing operations, while the triangular form offers up to three usable cutting edges per insert, improving economy per index. These geometric features are selected to maintain surface quality with minimal vibration, so final part tolerances are easier to hold and rework is reduced.

Practical integration and machining guidance

Compatibility with standard TCMT toolholders and clear ISO classification (ISO 513 group K) means the insert can be integrated quickly into existing toolsets for cast iron applications. The tolerance class M ensures consistent fit and repeatability across production batches. For best results, start with moderate cutting speeds and increase based on tool wear observations; the coated surface is optimised for abrasive materials, leading to extended tool life and stable chip control. The Walter Tools design and the Tiger·tec Silver technology together support a cost-effective machining strategy for abrasive cast iron components.

FAQ

What materials is this insert intended for?
The TCMT16T304-MK4 WKK10S insert is intended primarily for cast iron machining (ISO group K) and is optimised to handle the abrasive wear and short, breaking chips typical of these materials.

What advantages does the Tiger·tec Silver coating provide?
Tiger·tec Silver extends tool life through improved wear resistance and thermal stability; combined with the WKK10S grade, the coating reduces flank and crater wear during continuous cast iron turning.

How many cutting edges are available per insert?
The triangular TCMT design offers up to three usable cutting edges per insert, allowing economical indexing and straightforward replacement during scheduled maintenance.

Is the insert compatible with standard toolholders?
Yes; the TCMT16T304-MK4 form follows common TCMT insert standards and is compatible with matching TCMT toolholders for turning applications
