DCMT11T304-RM4 WMP20G turning insert — Walter Tools, Tiger·tec Gold, for stainless steel

The DCMT11T304-RM4 WMP20G is a coated carbide turning insert engineered for secure chip formation and reliable edge life when machining stainless steel under medium to robust conditions.

• DCMT11T304-RM4 WMP20G turning insert
• Tiger·tec Gold coated carbide grade
• Optimised RM4 chipbreaker for chips
• 7° clearance and 0.4 mm corner radius

Consistent productivity when machining stainless steel

The coated carbide grade WMP20G, based on Tiger·tec Gold technology, supports stable cutting edges and consistent chip formation when machining stainless steel. The composition and coating reduce the tendency to build up a cutting edge and to work-harden the material, which translates into fewer interruptions and more predictable tool life. As a result, process stability and component repeatability improve, contributing to a measurable rise in throughput and less frequent insert changes during production runs.

Precision geometry that reduces cycle time and rework

The insert geometry — a Rhombus 55° shape with 0.4 mm corner radius and 7° clearance — provides a balance between strength and accessibility for a wide range of turning tasks. The RM4 chipbreaker is optimised to break and evacuate chips effectively in the cutting zone, reducing the risk of surface damage and secondary operations. For workshops requiring dependable surface quality with minimal setup changes, this geometry offers enhanced tool life and reduced machine downtime through reliable chip control and stable cutting behaviour.

Coating benefits and application advice for reliable results

The Tiger·tec Gold coating on a fine-grain coated carbide substrate supports machining under medium to robust conditions and is particularly suited to the challenges of machining stainless steel, such as heat generation and material adherence. The coating improves thermal resistance and wear behaviour, helping to maintain a stable cutting edge during longer cycles. For selection and process parameters, consider the material group and cutting conditions; specialist guidance is available if the application falls between light finishing and heavier interrupted cuts.

FAQ

Which materials is this insert designed for?
The DCMT11T304-RM4 WMP20G insert from Walter Tools is designed primarily for stainless steel (ISO material group M) and performs well under medium to robust machining conditions.

What advantage does the RM4 chipbreaker provide?
The RM4 chipbreaker promotes controlled chip formation and evacuation, reducing the risk of built-up edge and improving surface finish when turning tougher, ductile materials.

What are the key geometry specifications of the insert?
The insert features a Rhombus 55° shape, 0.4 mm corner radius and 7° clearance, with a thickness of T3 and an insert size of 11 for versatile turning applications.

Is the grade coated and what does that mean for wear resistance?
Yes — the WMP20G grade is a Tiger·tec Gold coated carbide, providing improved thermal resistance and wear performance for extended edge life in stainless steel turning.

For which machining tasks does this insert excel?
The insert is well suited to general turning where secure chip control and reliable edge life are required, especially in operations that face moderate to robust cutting demands rather than ultra-fine finishing.
