SNMA190624-RK5 WKK20S turning insert — Tiger·tec Silver coated, for cast iron

SNMA190624-RK5 WKK20S is a square 90° indexable turning insert designed for productive machining of cast iron components, featuring the Tiger·tec Silver coating and an RK5 chipbreaker for controlled chip formation.

• Tiger·tec Silver coating for wear resistance
• Optimised for cast iron machining
• Square 90° insert geometry
• Corner radius 2.4 mm for robust cutting edges

Improved tool life and consistent performance for abrasive materials

The Tiger·tec Silver coating combined with the WKK20S grade is formulated to resist the abrasive wear commonly encountered when machining cast iron. The coated cemented carbide composition provides a stable wear pattern, so flank and crater wear develop predictably rather than suddenly. This translates into fewer interruptions for tool changes and a higher level of process reliability on the shop floor. Where repetitive batch runs are required, the controlled wear characteristics contribute directly to consistent component quality and reduced scrap rates.

Controlled chip formation and process stability

The RK5 chipbreaker is engineered to produce short, easily evacuable chips when turning grey and nodular cast irons. By promoting frequent chip breakage, the insert reduces the risk of entanglement and tool-to-workpiece interference, improving cycle times and operator safety. The square 90° geometry together with a 2.4 mm corner radius offers a balanced relationship between edge strength and form accuracy, making the insert suitable for both roughing and stable finishing passes in many shop applications.

Integration into production workflows and handling advice

With a tolerance class M and a standard plate size of 19 mm, the insert is intended for stable clamping in common toolholders and for use in serial production environments. Its negative 0° relief angle supports secure cutting engagement and predictable cutting forces under interrupted cuts. For best results, machining parameters should be adapted to the cast iron grade and machine rigidity; the insert’s design supports higher material removal rates while maintaining surface integrity. For specific cutting data or process optimisation, further technical details are available on request.

FAQ

What materials is this insert suited for?
The SNMA190624-RK5 WKK20S turning insert is optimised for machining cast iron; the WKK20S grade and Tiger·tec Silver coating are tailored to resist abrasive wear typical of such materials.

How does the RK5 chipbreaker affect machining?
The RK5 chipbreaker promotes short chip formation and reliable evacuation, improving process stability and reducing the likelihood of chip-related interruptions when turning cast iron.

Can this insert be used for finishing operations?
Yes, the square 90° geometry with a 2.4 mm corner radius provides sufficient edge strength for stable finishing passes, provided cutting parameters and machine rigidity are appropriate.

Which toolholder types are compatible with the insert size?
The 19 mm plate size and tolerance class M are compatible with standard turning toolholders that accept SNMA-style square inserts; proper clamping is essential for repeatable performance.
