DNMG110408-FM5 WMP20G – Turning indexable insert, rhombic 55° geometry, 0° negative rake (Walter Tools)

A DNMG110408-FM5 WMP20G turning insert engineered for robust stainless steel machining and optimised for secure chip formation in medium to demanding turning operations

• Tiger‑tec Gold coating for extended life
• WMP20G grade optimised for stainless steel
• Rhombic 55° insert with 0.8 mm radius
• Chipbreaker FM5 for consistent chip control

Longer tool life through advanced coating and grade

The combination of Tiger‑tec Gold surface technology with the WMP20G grade produces a coated carbide insert that resists wear and thermal load during prolonged turning cycles. This yields extended tool life and fewer tool changes, reducing machine downtime and overall process cost. For workshops facing variable stainless steel batches, the improved wear resistance of this system maintains a reliable edge even under intermittent high temperatures.

Consistent chip control and secure cutting performance

Equipped with the FM5 chipbreaker, the insert promotes predictable chip formation and evacuation, which reduces the risk of chip entanglement and protects workpiece surfaces. In practice, the chip geometry tailored to the grade leads to stable cutting forces and helps maintain finish quality on demanding stainless steel grades. The consistent chip control supports higher productivity by enabling steadier feeds and fewer interruptions.

Geometry explained: why rhombic 55° and 0° rake matter

The rhombic 55° shape provides a versatile cutting angle that balances strength and accessibility for external and light profiling operations. The 0° rake (negative) increases edge stability and is advantageous when cutting tougher stainless steels prone to work hardening. The 0.8 mm corner radius supports a robust cutting edge for medium-depth passes while still allowing acceptable surface finish, making the geometry suitable for general turning tasks and semi-finishing operations.

Process reliability and application guidance

This insert is principally suited to turning operations on stainless steel, where secure chip control and edge stability are priorities. The WMP20G grade is designed for moderate to robust cutting conditions typical of workshop and production environments. For best results, pair the insert with stable toolholders and moderate radial engagement; adapt feed and speed to the specific stainless grade to avoid excessive heat and achieve the intended tool life and surface integrity.

FAQ

What materials is this insert designed for? This Walter Tools turning insert is specified for machining stainless steel; the WMP20G grade and chipbreaker FM5 support secure chip formation on these materials.

How does the FM5 chipbreaker affect machining? The FM5 chipbreaker on this insert encourages predictable chips and smooth evacuation, which helps maintain surface finish and reduces interruptions in turning operations.

When is a 0° (negative) rake preferable? A 0° rake is chosen when increased edge resilience is needed; it is beneficial for tougher stainless steels and situations where a robust cutting edge reduces the likelihood of built-up edge.

Can the rhombic 55° shape be used for profiling? Yes, the rhombic 55° geometry provides access for external turning and light profiling while keeping adequate strength for semi-finishing passes.

What does the "04" in thickness indicate? The thickness designation "04" refers to the insert thickness specified by the standard product code and should be checked against toolholder compatibility before use.
