DCMT11T308-MM4 WSM30S Turning Insert – Walter Tools — Tiger·tec Silver, MM4 chipbreaker

DCMT11T308-MM4 WSM30S is a precision indexable turning insert designed for demanding applications in rostfreier Stahl and superalloys, offering stable cutting edges and consistent surface quality

• Tiger·tec Silver coating for increased wear resistance
• Reliable chip control with MM4 chipbreaker
• Rhombus 55° form for versatile turning operations
• 0.8 mm corner radius for balanced strength and finish

High-performance grade for rostfreier Stahl and superalloys

The insert uses the WSM30S grade within the Tiger·tec Silver technology, engineered for materials that generate high heat and demand stable cutting edges. This grade supports secure chip formation and reduces the risk of built-up edge when machining rostfreier Stahl, which typically requires thermal resilience and edge stability. The combination of coating and substrate delivers predictable wear behaviour, allowing longer tool life and fewer interruptions in production. The controlled flank wear pattern contributes to repeatable part accuracy and consistent surface finish.

Geometry and chip management that improve cycle times

A Rhombus 55° shape paired with a 7° relief and 0.8 mm corner radius provides a compromise between strength and accessibility in tight turning profiles. The MM4 chipbreaker is optimised for medium to heavy cuts in tough materials, guiding chips away from the cutting zone to reduce heat concentration and tool loading. Thickness T3 and the standard insert size ensure secure clamping in common turning toolholders, resulting in stable cutting forces and improved process reliability. These geometric choices translate directly into shorter cycle times and fewer rework operations.

Shop-floor advantages and application scope

This turning insert is intended for industrial workshops seeking reproducible performance when facing troublesome materials such as rostfreier Stahl and heat-resistant superalloys. The grade and chipbreaker combination reduce unexpected tool changes and support higher material removal rates without sacrificing surface quality. Integration into existing tool systems is straightforward thanks to the standard ISO form; replacement and indexation are fast, supporting lean manufacturing goals. Proven tool behaviour fosters confidence in repeated batches and aids in achieving tighter tolerances with lower process variability.

FAQ

What materials are recommended for this insert?
The DCMT11T308-MM4 WSM30S insert is recommended for rostfreier Stahl and heat-resistant superalloys; the WSM30S grade and Tiger·tec Silver coating provide thermal stability and robust edge performance.

How does the MM4 chipbreaker affect machining?
The MM4 chipbreaker controls chip shape and evacuation for medium to heavy cuts, reducing heat at the cutting edge and enhancing process stability when machining tough materials.

Can this insert be used in standard ISO toolholders?
Yes, the Rhombus 55° form and ISO-compliant geometry permit use in common indexable turning toolholders; thickness T3 ensures secure clamping.

What surface quality can be expected with this grade?
Thanks to the coating and stable cutting edge, the grade supports consistent surface finishes while permitting productive cutting parameters in rostfreier Stahl applications.

Is the insert suitable for high-speed finishing?
The Tiger·tec Silver technology and grade selection favour durability under elevated thermal stress; finishing at higher speeds depends on workpiece alloy and setup, but the insert offers good resistance to thermal wear.
