Reliable cutting in difficult alloys for fewer interruptions

The coated cutting geometry delivers stable chip formation and repeatable results when machining materials known for work hardening and poor thermal conductivity. The WSM20S grade, part of the Tiger‑tec Silver series, is developed to resist thermal and mechanical wear, which translates into longer uninterrupted tool life and fewer tool changes. By combining a wear‑resistant coating with a robust substrate, this insert maintains cutting-edge integrity under elevated cutting temperatures typical of machining stainless steels and superalloys, so cycle times and tool consumption are reduced.

Improved surface finish and predictable tool behaviour

A defined corner radius 1.2 mm and the rhombic 80° shape control cutting forces and contact conditions, helping to achieve a consistent surface quality on difficult‑to‑cut workpieces. The moderate clearance provided by the 7° relief reduces the tendency for edge build‑up while supporting secure seating in the toolholder. As a result, the component finish benefits from reduced vibration and more stable cutting, which is particularly important for finishing passes and tight tolerance work in demanding production environments.

Designed chip control and machining stability for productivity

The E47 chipbreaker geometry is focused on fragmenting and evacuating chips efficiently under variable feeds. This contributes to safer machining, reduced rework and less downtime caused by chip entanglement. The insert’s design supports both roughing and finishing sequences depending on the chosen cutting data, providing flexibility in process planning and supporting higher overall productivity in series production or specialised workpieces.

Practical selection and application guidance for process security

This insert is best applied in operations where materials fall under ISO groups M and S — in other words, stainless steels and heat‑resistant superalloys or titanium alloys. Selection of the WSM20S grade is advisable when thermal stability and edge retention are priorities. Combine the insert with a suitable toolholder matched to the rhombic 80° geometry and apply cutting data that respects the substrate’s properties: moderate feed to manage heat and a stable clamping system to exploit the insert’s benefits for consistent part quality.

FAQ

What materials is this insert suitable for?
The CCMT120412-E47 WSM20S insert is specified for ISO groups M and S, meaning it is suitable for stainless steels and heat‑resistant superalloys or titanium, depending on the application.

How does the Tiger‑tec Silver coating benefit machining?
The Tiger‑tec Silver coating on the WSM20S grade improves thermal resistance and reduces abrasive wear, which helps the insert sustain its cutting edge longer during demanding operations.

What does the E47 chipbreaker provide in practice?
The E47 chipbreaker is designed to control and break chips efficiently under varying feeds, improving chip evacuation and reducing the risk of tangling in turning and boring operations.

Which geometric features support surface quality?
The rhombic 80° shape combined with a corner radius 1.2 mm and 7° relief stabilises cutting forces and reduces edge build‑up, supporting a consistent surface finish on difficult‑to‑machine materials.

Is this insert suitable for both roughing and finishing?
Yes, depending on the chosen cutting parameters and toolholder, the insert can be used for both roughing and finishing; its wear resistance and chip control make it versatile across different passes.
