DNMG150404-MM5 WMP20G turning insert — rhombic 55°, MM5 chipbreaker (Walter Tools)

The DNMG150404-MM5 WMP20G is a rhombic 55° turning insert with Tiger·tec Gold coating, engineered for reliable, productive machining of stainless steel under medium to robust conditions.

• Tiger·tec Gold coated carbide
• Optimised chip control MM5
• Rhombic 55° geometry, r0.4
• For stainless steels (ISO M)

Consistent performance for stainless steel turning

The WMP20G grade, part of the Tiger·tec Gold series, is a coated carbide solution tailored to the specific demands of stainless steel machining. Its composition and coating support secure chip formation and resist thermal softening, which reduces the tendency for built-up edge and enables longer tool life. In production terms, this translates into fewer tool changes, steadier dimensional results and improved process reliability when turning austenitic and other stainless grades.

Geometry and edge integrity for demanding operations

The rhombic 55° shape combined with a 0° negative rake delivers a mechanically robust cutting edge that withstands heavy engagement and intermittent cutting. The small r0.4 corner radius provides a balance between strength and surface finish, while the MM5 chipbreaker promotes short, controllable chips in subcritical cutting conditions. Together these characteristics ensure stable cutting forces and predictable surface quality in both continuous and interrupted turning tasks.

Integration into production and measurable benefits

With a compact inscribed circle and a standard thickness code, the insert integrates easily into common tool holders and indexable tool systems. The tolerance class M indicates consistent manufacturing precision, aiding repeatability across batches. For workshops aiming to increase throughput on stainless components, the combination of Tiger·tec Gold wear resistance and the MM5 chip control yields a favourable cost-per-part balance through longer edge life and reduced secondary operations.

FAQ

What materials is this insert best suited for? The DNMG150404-MM5 WMP20G insert is optimised for machining stainless steel (ISO M), offering stable chip formation and edge resistance for austenitic and similar grades.

How does the MM5 chipbreaker affect cutting performance? The MM5 chipbreaker on this Walter Tools insert produces short, manageable chips and improves thermal control, which helps maintain a stable cutting edge and consistent surface finish.

Can the insert handle interrupted cuts? The combination of rhombic 55° geometry, r0.4 corner radius and 0° negative rake gives the insert the mechanical strength required for intermittent cutting and moderate interruption.

Is this insert compatible with standard DNMG tool holders? Yes; the DNMG150404-MM5 format conforms to common DNMG toolholder interfaces and can be indexed according to standard practice.

What does tolerance class M imply for production? Tolerance class M denotes consistent manufacturing accuracy, supporting repeatable positioning and predictable part tolerances when the insert is mounted and indexed.
