DNMG150408-MM5 WMP20G turning insert — Tiger·tec Gold coated, for stainless steel | Walter Tools

The DNMG150408-MM5 WMP20G is a rhombic 55° turning insert designed for reliable machining of stainless steels under medium to robust cutting conditions.

• Tiger·tec Gold coating for heat resistance
• MM5 chipbreaker for controlled chips
• Rhombic 55° form for versatile turning
• Negative 0° relief for stable cutting

Stable cutting in stainless-steel applications

The combination of the Tiger·tec Gold coating and a coated carbide substrate provides improved thermal stability and wear resistance, which directly benefits machining of stainless steel (ISO group M). The specialised MM5 chipbreaker supports predictable chip formation even when the material exhibits toughness and a tendency to form built-up edge. These design choices reduce unplanned downtime and contribute to a steadier surface finish, meaning fewer rework cycles and more consistent throughput in production environments.

Geometry engineered for repeatability and edge life

The rhombic 55° insert geometry with a 0° (negative) relief and a 0.8 mm corner radius combines rigidity with controlled cutting action. This geometry supports stable cutting forces and a robust cutting edge, which helps maintain dimensional accuracy across repeat operations. The insert thickness (04) and the DNMG format offer secure clamping and thermal mass, contributing to predictable tool life and repeatable turning performance on medium to heavy duty operations.

Productivity and process reliability for demanding conditions

Designed as part of the Tiger·tec Gold series and specified for stainless-steel machining, this turning grade is optimised for medium to robust conditions where both stable chip control and reliable edge retention are required. The grade WMP20G is a coated carbide developed to handle heat and adhesion challenges typical of these materials. The result is a cost-efficient solution for batch production and single-pass roughing where consistent quality and process safety are priorities.

FAQ

What materials is this insert best suited for?
The DNMG150408-MM5 WMP20G insert is specified for stainless steel (ISO group M) and is optimised to manage the toughness and heat characteristics associated with these alloys.

How does the MM5 chipbreaker improve machining?
The MM5 chipbreaker on the WMP20G grade promotes controlled chip formation and evacuation, enhancing process stability and reducing the risk of built-up edge during stainless-steel turning.

What advantage does the Tiger·tec Gold coating provide?
The Tiger·tec Gold coating increases thermal resistance and wear protection, which contributes to longer edge life and consistent cutting performance under elevated cutting temperatures.

Is the DNMG15 format suitable for heavy-duty turning?
Yes, the DNMG150408 format with a 0° negative relief and robust thickness offers the rigidity and clamping stability required for medium to robust turning operations.
