DCMT11T304-FM4 WMP20G turning insert — rhombic 55°, for rostfreien Stahl — Walter Tools

The DCMT11T304-FM4 WMP20G is a rhombic 55° indexable insert designed for turning operations on rostfreien Stahl under medium to robust conditions, combining a Tiger·tec Gold coating with an FM4 chipbreaker for stable machining.

• DCMT11T304-FM4 WMP20G by Walter Tools
• Tiger·tec Gold coating for secure chip control
• Optimised for rostfreien Stahl (ISO group M)
• 0.4 mm corner radius, 7° clearance for stability

Consistent process performance through a specialised grade

The Tiger·tec Gold WMP20G grade is a coated carbide formulation optimised for machining rostfreien Stahl, where toughness and heat generation demand a reliable cutting material. The coating and substrate pair reduce the tendency for built-up edge and help maintain a stable cutting edge, which translates into fewer interruptions and a more predictable component finish. For manufactures seeking improved process uptime, this combination reduces scrap risk and supports repeatable cycle times.

Geometry and chip control that protect the component surface

The rhombic 55° shape and the FM4 chipbreaker create a controlled chip flow that prevents long, stringy chips when working with ductile rostfreien Stahl. The 0.4 mm corner radius and 7° clearance distribute cutting forces and reduce edge stress, helping to preserve surface integrity and minimise vibration. These geometric features aid in achieving consistent dimensional accuracy and surface quality, especially on medium to heavy cuts.

Practical advantages for production and tool handling

The insert’s T3 thickness and standard 11 mm size make it compatible with many common toolholders, enabling straightforward integration into existing turning setups. The coated carbide construction from Walter Tools offers enhanced resistance against abrasive wear while the grade’s toughness supports interrupted cuts and moderate depths of cut. This balance between wear resistance and edge strength makes the insert suitable for mixed production runs where rostfreien Stahl is frequently encountered.

Process guidance and application scope

Intended primarily for the ISO group M, the insert is recommended for workpieces where heat generation and edge adhesion are concerns. In practice, the WMP20G grade performs well with parameters that favour controlled cutting speeds and steady feed rates; the FM4 chipbreaker assists in chip segmentation and evacuation. For shops aiming to improve productivity on rostfreie materials, the insert offers a dependable compromise between tool life and surface finish.
