TCMT16T312-RK4 WKK10S indexable insert – Tiger‑tec Silver coated, for cast iron | Walter Tools

A TCMT16T312-RK4 WKK10S triangular insert designed for turning and boring operations, optimised for abrasive cast iron machining with a robust RK4 chipbreaker and high‑performance Tiger‑tec Silver coating.

• Tiger‑tec Silver coated for extended life
• Optimised for cast iron machining
• RK4 chipbreaker for reliable chip control
• 7° clearance and 1.2 mm nose radius

Consistent performance for abrasive workpieces

The combination of a Tiger‑tec Silver coating with a coated carbide substrate ensures increased resistance to the abrasive wear typical of cast iron. The insert is supplied in the WKK10S grade, a Walter‑engineered composition that balances toughness and wear resistance for short, breaking chip forms. This results in fewer tool changes and a more predictable machining sequence, which contributes directly to improved throughput and reduced non‑productive time.

Geometry designed for edge strength and surface quality

The triangular 60° form with a 1.2 mm nose radius and a 7° clearance angle provides a stable cutting edge that withstands interrupted cuts and varying depths of cut. A larger nose radius supports higher feed rates during roughing while maintaining acceptable surface finish for semi‑finishing passes. Thanks to this geometry, the insert offers a practical compromise between component integrity and processing speed, with the RK4 chipbreaker assisting consistent chip segmentation.

Process reliability and economical machining

Because the grade and coating are tailored for cast iron, the insert delivers a predictable wear pattern and consistent cutting forces; this lowers the risk of unexpected edge failure. The TCMT16T312-RK4 WKK10S is particularly effective in operations where repeatability and minimal downtime are priorities. Machining cycles become more economical through extended edge life, reduced insert consumption and stable chip evacuation that supports automatic chip handling systems.

Practical application and integration into toolholders

The insert’s designation and dimensions match common triangular indexable holders used in turning and boring systems, allowing straightforward replacement and indexability during production runs. Its T3 thickness and 16 mm size make it suitable for a range of tool geometries where a compact, durable cutting edge is required. Selection of appropriate clamping and holder rigidity will further exploit the insert’s chip‑control characteristics and coating benefits, enhancing overall process security.

FAQ

Is this insert suitable for all types of cast iron?
The TCMT16T312-RK4 WKK10S is optimised for a broad range of cast iron types according to its WKK10S composition, but specific grades of cast iron with unusual abrasiveness should be discussed with Metav Werkzeuge for tailored recommendations.

How does the RK4 chipbreaker affect machining?
The RK4 chipbreaker on this insert promotes consistent chip segmentation when cutting cast iron, which supports reliable chip evacuation and reduces the likelihood of chip entanglement on the workpiece or toolholder.

What advantages does the Tiger‑tec Silver coating provide?
The Tiger‑tec Silver coating increases abrasive wear resistance and thermal stability, extending the effective life of the insert in demanding cast iron operations and maintaining dimensional consistency over longer runs.

Can this insert be used for finishing passes?
With its 1.2 mm nose radius and robust geometry, the insert can perform semi‑finishing tasks; final surface requirements should be validated under actual cutting conditions and with appropriate feed rates to achieve the desired finish.

Which toolholders are compatible with this insert designation?
The ISO designation TCMT16T312-RK4 corresponds to standard triangular indexable holders for turning and boring; compatibility with specific toolholders should be checked against holder manufacturer specifications.
