VNMG160404-FM5 WMP20G turning insert by Walter Tools — Tiger·tec Gold grade for rostfreiem Stahl

VNMG160404-FM5 WMP20G is an indexable turning insert designed for medium to robust machining of rostfreiem Stahl, offering a Rhombic 35° form and a controlled-chip FM5 geometry

• Tiger·tec Gold coating for wear resistance
• Suitable for rostfreiem Stahl (ISO group M)
• Rhombus 35° form with 0.4 mm nose radius
• FM5 chipbreaker for secure chip control

Maximise process reliability with a coated, application-oriented grade

The combination of the Tiger·tec Gold coating and the WMP20G grade supports consistent machining of rostfreiem Stahl, a group of materials prone to work hardening and built-up edge. The coated carbide construction promotes a stable cutting edge under higher temperatures, which reduces unexpected tool changes and contributes directly to predictable cycle times. The FM5 chipbreaker is tuned to produce controllable chip forms when turning stainless-type alloys, helping to avoid chip entanglement and downtime. This results in a measurable improvement in process reliability for batch and continuous production.

Achieve consistent surface quality with controlled geometry

The Rhombus 35° insert geometry and a 0.4 mm nose radius allow for a balance between stock removal and surface finish, making the grade suitable for both semi-finishing and finishing passes on rostfreiem Stahl. The insert’s 0° negative rake gives a robust cutting edge that tolerates interrupted cuts and heavier engagement without rapid edge chipping. As a result, components reach consistent dimensional and surface specifications more quickly, reducing rework and supporting higher first-pass yield. The durability of the coating also means longer in‑process tool life, lowering tooling consumption over time.

Practical compatibility and predictable handling in the workshop

The VNMG form is a common indexable insert footprint compatible with standard clamping systems and holders for turning applications; the VNMG160404-FM5 WMP20G insert fits conventional tool posts and facilitates rapid index changes to restore geometry. The FM5 chip control geometry simplifies swarf management on machines without complex chip conveyors, while the coated grade reduces the frequency of edge inspections. For production engineers and operators, this translates into simpler tool inventories and more predictable maintenance intervals, supporting leaner workflows and reduced setup variability.

FAQ

What materials is this insert intended for?
The VNMG160404-FM5 WMP20G is specified for machining rostfreiem Stahl (ISO group M) and is optimised for the typical challenges of those alloys.

Is the insert suitable for finishing passes?
Yes, the 0.4 mm nose radius and Rhombus 35° form support both semi-finishing and finishing, delivering consistent surface quality when used with appropriate cutting parameters.

How does the FM5 chipbreaker affect machining?
The FM5 chipbreaker produces controlled chip forms for rostfreiem Stahl, reducing chip-related interruptions and improving process reliability during turning operations.

Can the insert be indexed to restore the cutting edge?
The VNMG form is indexable; rotating to a fresh edge restores the intended geometry and helps maintain consistent cutting performance.
