DCMT11T302-FM4 WMP20G – Turning insert, Tiger·tec Gold for rostfreier Stahl (Walter Tools)

A DCMT11T302-FM4 WMP20G turning insert engineered for precision turning of rostfreier Stahl with a 55° rhombus geometry and FM4 chipbreaker for stable machining.

• Tiger·tec Gold coating, WMP20G grade
• FM4 chipbreaker for stable chip control
• 55° rhombus geometry for versatile cutting
• 0.2 mm corner radius for fine surface finish

Consistent performance for demanding rostfreier Stahl operations

The Tiger·tec Gold coating in combination with the WMP20G grade is designed to manage the thermal and adhesive challenges typical of rostfreier Stahl. This indexable insert offers a balance of wear resistance and toughness that reduces edge build-up and extends tool life under medium to robust cutting conditions. The result is fewer interruptions for tool changes, improved component quality and a measurable increase in process reliability.

Geometry and edge form tuned for surface quality

A 55° rhombus form paired with a 0.2 mm corner radius delivers controlled cutting engagement and reproducible surface finish on turned parts. The insert’s relief angle of 7° supports stable cutting forces and predictable tool behaviour, helping to maintain dimensional consistency across repeated cycles. For shops machining parts where finish and repeatability matter, the geometry simplifies setup and reduces rework.

Chip control and efficiency through FM4 chipbreaker design

The FM4 chipbreaker is optimised to form short, controllable chips when turning rostfreie Werkstoffe, minimising entanglement and improving evacuation. Better chip control reduces machine downtime and the risk of surface damage, while contributing to safer, more efficient production. The insert’s compact form factor and validated grade contribute to economical productivity by prolonging edge life and lowering overall tooling costs.

Practical application and handling advice

The insert is supplied in the DCMT format with a T3 thickness designation and is suitable for a broad range of turning tasks in rostfreier Stahl. Its combination of coating, chipbreaker and geometry makes it a reliable choice for batch production and single-part runs where steady performance and process security are priorities. For best results, pair the insert with a compatible WC toolholder and apply cutting parameters aligned with the workpiece grade and machine rigidity.
