DCMT070204-FM4 WMP20S Drehwendeschneidplatte by Walter Tools — Rhombic 55°, 7° relief

A DCMT070204-FM4 WMP20S indexable turning insert designed for precision turning of rostfreier Stahl under medium to robust cutting conditions

• Tiger·tec Silver coating for longer tool life
• WMP20S grade optimised for rostfreier Stahl
• FM4 chipbreaker for secure chip control
• Rhombic 55° geometry for versatile turning

Stable machining performance for rostfreier Stahl

The coated carbide combination of Tiger·tec Silver and grade WMP20S is tailored to the challenges of machining rostfreier Stahl, where toughness and build‑up tend to compromise edge stability. The rhombic 55° geometry and the fine corner radius 0.4 deliver a controlled engagement and predictable tool behaviour, reducing the risk of unexpected edge damage. This results in consistent cutting forces and improved process reliability during both semi‑finishing and finishing operations.

Consistent chip control and surface quality

Equipped with the FM4 chipbreaker, this insert promotes secure chip formation and evacuation even under the higher heat and stickiness typical of rostfreier Stahl. The relief angle 7° helps to reduce rubbing while maintaining a stable cutting edge. Together these features support a superior surface finish and minimise rework cycles, helping production lines to keep tolerances tight and save time on downstream operations.

Practical benefits for production workflows

The compact Rhombic 55° insert shape provides flexibility across a range of turning tasks, enabling quick adaptation between contouring and plunge cuts. The coated, indexable design allows rapid insert changes and predictable tool life, which simplifies inventory planning and reduces machine downtime. Where repeatability and process security are priorities, the insert’s engineering supports steady, reproducible results that favour cost‑efficient production.

FAQ

What materials is this insert suitable for?
The insert is specified for machining rostfreier Stahl and is optimised for medium to robust cutting conditions in this material group.

Which chipbreaker does the insert use and what is the benefit?
The FM4 chipbreaker ensures controlled chip formation and reliable evacuation when turning rostfreier Stahl, improving surface quality and process stability.

How does the Tiger·tec Silver coating help in production?
Tiger·tec Silver increases resistance to wear and supports a stable cutting edge under the thermal and mechanical stresses associated with rostfreier Stahl machining.

Is the insert compatible with standard toolholders for DCMT geometry?
Yes, the insert follows the DCMT geometry and fits standard toolholders designed for rhombic 55° turning inserts with the corresponding clamping system.

What does the WMP20S grade indicate?
WMP20S denotes Walter’s coated carbide grade optimised for rostfreier Stahl, balancing wear resistance and edge stability for repeatable performance.
