DCMT11T304-RM4 WMP30G turning insert — rhombic 55° for stainless steels by Walter Tools

The DCMT11T304-RM4 WMP30G is a rhombic 55° turning insert designed for robust and repeatable machining of stainless steels under medium to demanding conditions

• Tiger·tec Gold coating for stable edges
• Optimised RM4 chipbreaker for secure chips
• 7° clearance for controlled cutting
• 0.4 mm corner radius for robust performance

Increase process reliability with a coating engineered for edge stability

The combination of the WMP30G grade and Tiger·tec Gold coating promotes stable chip formation and improved resistance to thermal wear when machining stainless steels. This design reduces the risk of built-up edge and supports a predictable tool life, which in turn improves machine uptime and reduces unscheduled tool changes. The insert is made from coated carbide, formulated to handle the toughness and heat generation typical of these alloys, and is particularly suitable where consistent cutting performance is required.

Achieve consistent part quality through geometry and edge preparation

The rhombic 55° form and a 0.4 mm corner radius deliver a balance between strength and access for profile work. A 7° relief angle reduces rubbing at the flank and helps maintain surface finish while the geometry supports axial and radial clearances typical for general turning applications. Together these features contribute to reproducible surface integrity and dimensional stability, making the insert appropriate for serial production or small-batch work that demands repeatable results.

Save time on setup and maintain steady productivity

The insert's RM4 chipbreaker is optimised for chip control during moderate to robust cutting and assists in consistent evacuation when turning materials classified in the M group. Compatibility with standard toolholders is supported by the DCMT form factor, enabling straightforward integration into existing toolsets. The construction and coating focus on productivity: fewer tool changes, improved edge retention and a lower incidence of cutting interruptions — factors that directly support shop-floor efficiency.

Practical recommendations for best results

For turning operations in stainless steels, a steady feed and appropriate cooling strategy help exploit the WMP30G grade’s strengths: the coating resists thermal softening while the chipbreaker manages formation and flow. Where possible, ensure correct clamping and stable workholding to make the most of the insert’s edge security. When processing harder or highly adhesive stainless grades, review cutting conditions incrementally to identify the optimal balance between speed, feed and coolant to preserve tool life and part finish.
