CCMT120404-FM4 WSM30S FM4 Wendeplatten - Walter Tools

Take advantage of a coated-carbide grade optimised for demanding materials and robust chip control: the combination of Tiger·tec Silver coating and the WSM30S grade ensures stable edge life when machining rostfreier Stahl and heat-resistant alloys, while the FM4 chipbreaker improves chip flow and process reliability; order via Metav Werkzeuge or request application advice from the consultants.

CCMT120404-FM4 WSM30S Boring/turning indexable insert — Tiger·tec Silver grade by Walter Tools

The CCMT120404-FM4 WSM30S is a rhombic 80° coated carbide insert developed for turning and boring operations on demanding materials, offering controlled chip formation and enhanced edge stability.

• Tiger·tec Silver coating for long tool life
• Optimised FM4 chipbreaker for reliable chips
• Rhombic 80° form for versatile turning and boring
• Suited for rostfreier Stahl and superalloys

Consistent wear resistance for stable production

The insert combines the WSM30S coating grade of the Tiger·tec Silver family with a coated-carbide substrate to provide predictable wear behaviour when machining tough alloys. The material formulation is tailored to counteract the adhesion and built-up edge tendencies typical of rostfreier Stahl, supporting longer tool life and fewer interruptions. This results in steadier component tolerances and reduced tool-change frequency, which directly benefits process uptime and overall throughput.

Improved chip control that keeps cycles predictable

Equipped with the FM4 chipbreaker, the geometry promotes controlled chip formation under varying cutting conditions. The chip control design reduces the risk of snarled or long chips during both roughing and finishing passes, aiding operator safety and machine cleanliness. As a consequence, cycle times remain consistent and the downstream handling of swarf becomes less labour intensive, supporting a more efficient production rhythm.

Geometry engineered for flexible turning and boring tasks

The Rhombus 80° profile and a 0.4 mm corner radius deliver a balance between strength and accessibility in axial and radial cuts. A clearance angle of 7° reduces rubbing on the flank while preserving edge support, making this insert suitable for interrupted cuts and mixed turning/boring setups. The geometry allows simple integration into standard toolholders used for both internal and external operations, giving machine shops flexibility without complex fixture changes.

Selection and application guidance for demanding alloys

Optimised for applications classified under ISO groups M and S, the grade is intended for rostfreier Stahl, heat-resistant superalloys and titanium where thermal loads and material toughness challenge the cutting edge. The coated-carbide substrate with Tiger·tec Silver technology supports high process stability and consistent surface quality. When selecting parameters, prioritise feed rates that ensure effective chip breakage with the FM4 geometry and adjust cutting speeds according to workpiece alloy and machine rigidity to preserve edge life.

FAQ

Which materials are best machined with this insert?
The CCMT120404-FM4 WSM30S is designed primarily for rostfreier Stahl (ISO group M) and heat-resistant superalloys or titanium (ISO group S), offering improved edge life under thermal and adhesive stress.

What does the FM4 chipbreaker provide in practice?
The FM4 chipbreaker ensures controlled chip segmentation and evacuation during turning and boring, reducing the occurrence of long, hazardous chips and aiding consistent cycle times with the Walter Tools insert.

Is the insert suitable for interrupted cuts and mixed operations?
Yes, the rhombic 80° form combined with a 7° clearance and a 0.4 mm corner radius provides edge support and accessibility, making it appropriate for interrupted cuts and versatile turning/boring setups.

How should cutting parameters be adapted for rostfreier Stahl?
When machining rostfreier Stahl with the WSM30S grade, favour moderate to elevated feeds to promote effective chip breakage with FM4 and adjust speeds to reduce heat concentration; the grade is optimised for stable cutting under these conditions.

Can this insert be used in standard toolholders for internal boring?
The geometry is compatible with common toolholder types for both external turning and internal boring; verify the holder clamping compatibility with the CCMT insert seat before assembly.
