DCMT11T308-RM4 WMP30G — indexable turning insert for stainless steel, Rhombus 55°, Walter Tools

The DCMT11T308-RM4 WMP30G is an indexable turning insert designed for medium to robust conditions when machining stainless steel, featuring a dedicated RM4 chipbreaker and Tiger·tec Gold coating for improved process security

• Tiger·tec Gold coated carbide grade WMP30G
• Optimised RM4 chip control for tough materials
• Rhombus 55° geometry, 0.8 mm corner radius
• Suitable for machining stainless steel

Increased process security and consistent tool life

The combination of the Tiger·tec Gold technology and the WMP30G grade provides a high degree of wear resistance and thermal stability in demanding turning operations. Coated carbide substrates in this series are engineered to mitigate common issues when cutting stainless steel, such as edge build-up and rapid heat concentration. The Rhombus 55° form and the small 0.8 mm corner radius support reproducible cutting forces and help maintain dimensional stability on stepped or contoured parts. For production-focused workshops, this translates into fewer interruptions for tool changes and more consistent part quality.

Controlled chip formation and improved surface finish

The insert’s RM4 chipbreaker is optimised to produce short, manageable chips under medium to robust cutting conditions, reducing the risk of entanglement and improving operator safety. With a free cutting angle of 7° and the insert’s geometry tuned for stainless applications, the result is a smoother surface and reduced tendency for built-up edge. By adopting this insert in appropriate cutting windows, cycle times remain competitive while tool life is extended, supporting both productivity and process repeatability.

Practical guidance for integration into workflows

Designed as a versatile option for rotating operations, the insert fits standard toolholders compatible with the DCMT form factor and a plate size of 11. The T3 plate thickness and the Rhombus 55° outline allow secure clamping and predictable engagement in interrupted cuts. For workshops seeking immediate improvements in stainless steel turning, pairing the insert with stable clamping, correct coolant strategy or appropriate cutting speeds for the material class will deliver the best balance between performance and tool economy. For detailed parameter windows or material-specific recommendations, technical consultation is available.
