CNMG120412-RP5 WKK10S Drehwendeschneidplatte — Tiger·tec Silver grade, for cast iron

A CNMG120412-RP5 WKK10S indexable turning insert designed for efficient, predictable machining of cast iron components in production environments

• Tiger·tec Silver coating for long tool life
• Optimised for cast iron machining (ISO K)
• RP5 chipbreaker for controlled chip formation
• Rhombic 80° geometry with 1.2 mm corner radius

Consistent wear resistance for productive machining

The combination of the Tiger·tec Silver coating and the WKK10S grade provides a robust solution for abrasive cast‑iron applications. The coated carbide construction reduces flank and crater wear, extending edge life and enabling longer uninterrupted cutting cycles. This translates directly to higher machine utilisation and lower tool‑change frequency, supporting more economical series production. The result is repeatable performance and reduced process variability when machining components from ISO‑classified cast iron.

Geometry and chip control that stabilise the cutting process

The rhombic 80° shape together with the RP5 chipbreaker is tuned for the short, brittle chips typical of cast iron. The 1.2 mm corner radius increases edge strength without compromising accessibility in many turning operations, while the 0° (negative) clearance supports robust cutting under interrupted or heavy cuts. Together these features produce controlled chip formation, improved surface quality and a lower risk of tool or workpiece damage, which enhances process security on automated lathes and production lines.

Practical process benefits and handling advantages

As a standard CNMG insert, this grade fits common toolholders and indexable systems, simplifying stockkeeping and re‑tooling. The insert’s design focuses on stable cutting and predictable wear behaviour, helping to maintain component tolerances across batches. Fewer regrinds and predictable edge life support planning for consumables and reduce unexpected downtime. For customers seeking to optimise throughput in cast‑iron turning, the insert brings a balance of durability, chip control and geometric flexibility that supports both roughing and semi‑finishing tasks.

FAQ

Which materials are recommended for this insert?
The CNMG120412-RP5 WKK10S insert is optimised for cast iron (ISO K); the WKK10S grade and Tiger·tec Silver coating are balanced for abrasive wear and short, breaking chips typical of these materials.

What does the RP5 chipbreaker achieve in practice?
The RP5 chipbreaker promotes short, controllable chips and consistent chip evacuation when using the CNMG120412-RP5 WKK10S, improving surface finish and reducing the risk of chip entanglement in turning operations.

How does the 80° rhombic geometry benefit turning operations?
The rhombic 80° geometry provides good cutting edge engagement and flexibility for various turning tasks; when paired with the 1.2 mm corner radius, it increases edge strength for heavy cuts while retaining contour access.

Is the insert compatible with standard CNMG toolholders?
Yes, the insert follows the CNMG geometry and fits conventional CNMG toolholders, enabling straightforward integration into existing tooling systems for production environments.
