Consistent performance for stainless steel turning

The coated carbide grade delivers a balance between wear resistance and edge strength. The Tiger·tec Silver technology improves thermal resistance and supports stable chip formation, which reduces the risk of built-up edge when machining stainless steel (ISO group M). As a result, process reliability is increased and interruptions for tool changes are less frequent, which benefits throughput and cost per part. The insert’s design prioritises steady cutting behaviour in demanding environments.

Geometry that enhances surface quality and repeatability

The rhombic 80° form combined with a 7° clearance angle and a 0.4 mm corner radius produces predictable cutting forces and improved surface finish on turned components. The RM4 chipbreaker is tuned to promote short, manageable chips in many stainless grades, helping to avoid entanglement and tool damage. With a nominal T3 thickness and standard CCMT footprint, the component enables secure clamping in compatible tool holders and contributes to consistent, repeatable results across batches.

Lower tooling costs through longer life and fewer interventions

The coated grade and robust edge geometry work together to extend effective tool life. Fewer indexings and less downtime for insert changes mean higher productivity on lathes and turning centres. The combination of wear-resistant coating and optimised chip control translates into measurable savings on consumables and machine time, making the insert an economical choice for series production and maintenance-friendly operations.

Application scope and practical guidance

Engineered primarily for stainless steel applications, the insert performs well under medium to robust cutting regimes where heat and ductility challenge the cutting edge. The designation WMP20S signals a coated carbide solution intended to support secure machining of ISO group M materials. For uncertain or specialised applications, technical consultation is recommended to match insert geometry and grade to the workpiece grade and machining strategy.

FAQ

Which materials is this insert suitable for?
The CCMT09T304-RM4 WMP20S insert is designed primarily for stainless steel (ISO group M) and performs under medium to robust cutting conditions.

What advantages does the Tiger·tec Silver coating provide?
The Tiger·tec Silver coating increases thermal stability and wear resistance, supporting longer tool life and more consistent cutting performance on tough, heat-generating stainless steels.

How does the RM4 chipbreaker influence machining?
The RM4 chipbreaker promotes controlled chip formation that reduces the risk of long, stringy chips and supports secure evacuation, improving process safety and surface quality during turning.

Is the insert compatible with standard CCMT tool holders?
The insert uses the CCMT geometry and rhombic 80° form, making it compatible with conventional holders designed for CCMT inserts; correct seating and clamping in the tool holder are essential for repeatable results.

What effect does the 0.4 mm corner radius have on the workpiece?
A 0.4 mm corner radius balances edge strength and surface finish: it helps absorb cutting shocks and extends edge life while still producing acceptable surface quality for many turned components.
