DCMT11T304-RM4 WMP20S turning insert — Walter Tools, Tiger·tec Silver grade for rostfreier Stahl

The DCMT11T304-RM4 WMP20S is a rhombic 55° indexable turning insert designed for reliable machining of rostfreier Stahl under medium to robust conditions

• Tiger·tec Silver coating for tough materials
• Optimised RM4 chipbreaker for secure chip control
• Rhombic 55° geometry for versatile turning
• 0.4 mm corner radius with 7° relief

Improved process security and longer tool life

The combination of the Tiger·tec Silver coating and the WMP20S carbide grade delivers noticeable increases in wear resistance and edge stability. The coating supports low friction and thermal resistance, which reduces wear mechanisms common in rostfreier Stahl machining. As a result, the insert maintains a consistent cutting edge for longer periods, which contributes to fewer tool changes and more predictable cycle times. This performance translates directly into improved process security and reduced downtime in series production.

Predictable chip control for demanding stainless applications

The RM4 chipbreaker is engineered to promote stable chip formation when machining tough, adhesive materials. In practice, the breaker geometry forces chips to curl and fragment reliably, lowering the risk of long, entangling swarf and improving surface quality. For operations where coolant strategy and evacuation are critical, the controlled chip flow reduces manual intervention and helps maintain consistent part finishes. This makes the insert particularly valuable for applications that demand repeatability and safe chip handling.

Geometry tailored for versatile turning and surface quality

The rhombic 55° shape provides a balanced approach between entry angle and cutting force, enabling versatile turning tasks from light finishing to medium roughing when combined with the 0.4 mm corner radius. The small radius increases edge strength without compromising surface finish, while the 7° relief angle supports secure cutting under variable depths of cut. Together these geometric choices deliver both dimensional accuracy and a fine surface quality on components made from rostfreier Stahl.

Practical application and programming guidance

Used as a series insert in shop-floor turning, the WMP20S grade suits machining strategies where moderate robustness and reliable chip control are priorities. The insert’s tolerance class M supports consistent seat fit and repeatable indexability in standard toolholders. For CAM programming, starting parameters can favour slightly reduced cutting speeds and increased feed per tooth compared with carbon steel to mitigate work-hardening; the coating and chipbreaker then enable steady material removal with predictable tool life.
