Consistent edge performance for demanding rostfreier Stahl machining

The coated carbide grade WMP20G, part of the Tiger‑tec Gold series, offers a balance of wear resistance and toughness that supports reliable machining of rostfreier Stahl. The insert’s design reduces build‑up of material on the cutting edge, so component tolerances remain stable across longer tool cycles. With a clearance angle of 7° and a precisely formed cutting geometry, the insert delivers repeatable cutting conditions, translating to fewer tool changes and improved uptime. This section focuses on measurable production benefits rather than abstract claims, emphasising process stability and reduced scrap rates.

Better chip control and surface quality through optimised geometry

Equipped with the RM4 chipbreaker and a 0.8 mm nose radius, the insert promotes controlled chip formation under variable cutting conditions. Controlled chips reduce the risk of rework and machine downtime, particularly when dealing with the sticky, heat‑sensitive behaviour of rostfreier Stahl. The square 90° form provides robust corner strength for shoulder cuts and interrupted cuts, offering a reliable balance between strength and finish. Clear technical attributes lead to practical advantages: fewer interruptions, consistent surface quality and predictable tool life.

Robust construction and straightforward integration into workflows

The insert’s coated carbide substrate and the Tiger‑tec Gold coating technology combine to offer good resistance to abrasive and adhesive wear while maintaining a stable cutting edge. The format SCMT09T308‑RM4 is compatible with common clamping systems for indexable turning, enabling quick insert changes and straightforward inventory management. Designed for industrial production, the insert supports optimisation of cycle times and tool utilisation rates. Where process reliability matters, this solution integrates into existing toolholders with minimal adaptation.

Process support and selection guidance for secure implementation

For workshops upgrading tooling for rostfreier Stahl, selecting the right grade and chipformer is crucial. The WMP20G grade is specified for medium to robust conditions and is particularly suited where sticky chip formation and thermal load demand a balanced coating and substrate. When combining this insert with appropriate feeds and speeds adapted to the component geometry, operators can expect improved edge stability and predictable wear patterns. If further machining data or comparators are required, technical advisors can supply cutting parameters aligned to the specific machine and workpiece setup.

FAQ

What materials is this insert intended for?
The SCMT09T308‑RM4 WMP20G insert is specified for rostfreier Stahl and designed to handle the toughness and thermal behaviour typical of these alloys.

How does the RM4 chipbreaker affect machining?
The RM4 chipbreaker provides consistent chip segmentation and evacuation, reducing the likelihood of entanglement and improving process stability when turning rostfreier Stahl.

Is the insert compatible with standard turning toolholders?
Yes, the SCMT09T308‑RM4 format conforms to common indexable insert geometries and can be used with suitable square insert toolholders for secure clamping and easy indexation.

What advantage does the Tiger‑tec Gold coating offer?
Tiger‑tec Gold on the WMP20G grade enhances wear resistance while maintaining edge toughness, which supports longer tool life under medium to robust cutting conditions on rostfreier Stahl.

Can this insert be used for interrupted cuts?
The square 90° form and robust corner geometry make the insert appropriate for interrupted cuts and shoulder machining, offering good resistance to mechanical shock.
