DNMG110404-MM5 WMP20G turning insert — Walter Tools, Tiger·tec Gold, for stainless steel

The DNMG110404-MM5 WMP20G is a rhombic 55° turning insert designed for medium to robust machining of stainless steel, offering a coated hardmetal grade tuned for secure chip formation and process stability.

• Tiger·tec Gold coating for long life
• Optimised MM5 chipformer
• 0.4 mm corner radius for strength
• Rhombus 55° geometry for versatile turning
• Negative relief angle 0° for stable cutting

Longer tool life and thermal stability from advanced coating

The combination of Tiger·tec Gold and the WMP20G grade gives a pronounced improvement in edge durability when machining stainless steel. The multilayer coating reduces flank wear and supports higher cutting temperatures, which translates into fewer tool changes and improved uptime. For production environments that prioritise steady cycle times, this coating technology helps maintain cutting-edge integrity under the thermal stresses typical of stainless turning operations, delivering a measurable increase in process efficiency.

Precise chip control and geometry for dependable results

The insert’s MM5 chipformer and Rhombus 55° shape yield controlled chip breaking and predictable chip flow, which is particularly valuable when working with tough, ductile materials. The 0.4 mm corner radius balances edge strength and surface finish, while the negative 0° relief angle contributes to a stable cutting edge under interrupted or heavy cuts. Together, these geometry choices reduce the risk of built-up edge and support consistent dimensional accuracy during longer tool life cycles.

Productivity and process security suited to daily production

Manufactured by Walter Tools, this indexable solution focuses on process reliability and repeatable performance. The combination of a tailored grade, robust chip control and a stable insert form supports continuous production with fewer quality fluctuations. For shops aiming to raise throughput without sacrificing surface integrity, the insert offers a pragmatic balance between process security and productivity, reducing downtime and simplifying grade selection across stainless steel turning tasks.

FAQ

Which materials is this insert intended for?
The DNMG110404-MM5 WMP20G is designed primarily for stainless steel; the WMP20G grade and Tiger·tec Gold coating support secure chip formation and wear resistance when machining stainless materials.

How does the MM5 chipformer improve turning performance?
The MM5 chipformer promotes short, controllable chips and stable evacuation under typical stainless turning conditions, helping to reduce built-up edge and maintain surface quality when using this DNMG insert.

What are the key dimensions and geometry of this insert?
The insert features a size designation of 11, a thickness of 4 mm and a corner radius of 0.4 mm; it uses a Rhombus 55° form with a negative 0° relief angle, suitable for versatile turning operations.

Is this insert better for roughing or finishing operations?
The WMP20G grade and MM5 chip control provide a compromise between robustness and surface finish, making the insert suitable for both medium roughing and finish passes in stainless steel, depending on cutting parameters.

Which toolholders accept this insert style?
This DNMG-style turning insert fits standard DNMG-compatible toolholders and indexable turning systems; the Rhombus 55° form allows flexible seatings in many common turning toolholders.
