VCMW160404-RK6 WKK10S — Turning insert, Tiger‑tec Silver grade, for cast iron (Walter Tools)

The VCMW160404-RK6 WKK10S is a precision turning insert optimised for efficient and repeatable machining of cast iron components in production environments.

• Tiger‑tec Silver coating
• Grade WKK10S for cast iron
• RK6 chipbreaker for controlled chips
• Rhombic 35° geometry with 0.4 mm radius

Boosted throughput for cast iron production

The Tiger‑tec Silver coating combined with the WKK10S grade delivers a balance between wear resistance and toughness that is beneficial for abrasive cast-iron workpieces. By selecting a cutting grade designed for cast iron, countertop tool life is extended and unscheduled tool changes are reduced, resulting in measurable productivity gains. The coated carbide construction ensures reliable performance under the short, breaking chip characteristics typical of cast materials, supporting higher cutting volumes and steady production flow.

Consistent surface finish and edge stability

The RK6 chipbreaker is specifically profiled to promote chip control during interrupted or continuous turning of cast iron, helping to maintain a uniform cutting zone and reducing built-up edge. Together with the rhombic 35° form and 0.4 mm corner radius, the insert offers improved load distribution at the cutting edge, which stabilises the process and contributes to repeatable surface quality. These design choices translate into fewer rework operations and a more predictable part finish.

Geometry and angles that support process security

A relief angle of 7° and the compact plate dimensions (16 mm size, 4 mm thickness) provide a rigid insert geometry that resists edge deformation during machining. The combination of small corner radius and robust substrate enables fine finishing passes as well as general turning operations, delivering flexibility within a single insert family. This geometry is advantageous in automated setups where consistent contact conditions and low vibration are essential for dimensional accuracy.

Practical integration and tooling recommendations

The insert is suitable for standard turning toolholders that accept rhombic 35° inserts and is especially advantageous in applications where frequent chip breaking is required. For optimum results in cast-iron operations, pair the insert with stable clamping and moderate feed rates to exploit the WKK10S wear characteristics and the Tiger‑tec Silver technology. The result is reduced downtime, predictable tool life and economical operation across batch sizes.
