CNMM190612-HU5 WMP20G turning insert — rhombic 80°, 1.2 mm nose radius, for rostfreier Stahl — Walter Tools

CNMM190612-HU5 WMP20G is a rhombic 80° turning insert designed for medium to robust machining of rostfreier Stahl, combining a coated carbide grade with a dedicated chipformer for controlled cutting performance

• Tiger·tec Gold coating for long tool life
• WMP20G grade for rostfreier Stahl applications
• HU5 chipbreaker for stable chip control
• Rhombic 80° form with 1.2 mm nose radius

Durable coating and grade for demanding rostfreier Stahl operations

The combination of the Tiger·tec Gold coating with the WMP20G grade delivers a coated carbide chemistry optimised for machining rostfreier Stahl under medium to robust conditions. This engineered pairing supports consistent cutting performance by improving wear resistance and preserving the cutting edge at elevated temperatures. As a result, the insert provides extended component runs and fewer tool changes, contributing to stable production cycles and predictable productivity gains.

Stable chip control and geometry that improves surface finish

The HU5 chipbreaker and the 0° (negative) relief angle work together to control chip formation when turning stubborn, work-hardened stainless materials. The 1.2 mm nose radius and rhombic 80° geometry enable a compromise between strength and detail in the turned profile: the radius smooths the finish while the rhombic form gives access to typical turning toolholder orientations. The insert’s geometry aids in heat distribution and reduces the risk of built-up edge, which leads to improved repeatability and a better surface on each component.

Productivity advantages in everyday workshop use

Designed as an indexable solution, this insert supports short changeover times and easy seat replacement for uninterrupted production. The coated carbide grade and chipformer combination reduce unplanned wear and enhance process reliability, which is especially valuable in batch production or when running series components. The insert’s attributes support both consistent cycle times and lower overall tooling consumption, favouring efficient shop-floor processes and cost-effective machining strategies.

Where this insert adds most value

Ideal for turning operations on rostfreier Stahl where tool life and chip control are critical, the insert suits general turning, light profiling and routine finishing passes under moderate to heavy cutting regimes. The CNMM190612-HU5 WMP20G insert is compatible with standard toolholder systems accepting CNMM-style geometry; for precise holder matching and parameter optimisation, consult the technical advisers to align feeds and speeds with the workpiece specification and machine capability.

FAQ

What materials is this insert intended to machine?
The CNMM190612-HU5 WMP20G insert from Walter Tools is designated for machining rostfreier Stahl and is optimised for the toughness and thermal behaviour typical of that material group.

How does the HU5 chipbreaker affect performance?
The HU5 chipbreaker promotes predictable chip formation and evacuation during turning, which helps maintain a stable cutting edge and improves surface quality when using the WMP20G grade on rostfreier Stahl.

Which geometry details matter when selecting a toolholder?
The rhombic 80° form and the 1.2 mm nose radius determine the seating and approach angle; choose a CNMM-compatible toolholder that matches the insert geometry to ensure correct cutting edge engagement.

Is the Tiger·tec Gold coating beneficial for longer runs?
Yes, the Tiger·tec Gold coating on the WMP20G grade increases wear resistance and thermal stability, extending tool life and supporting longer, uninterrupted production runs.

Can this insert be used for finishing passes?
The combination of the 1.2 mm nose radius and the coated grade makes the insert suitable for finishing and semi-finishing operations on rostfreier Stahl; fine-tuning of feeds and speeds is recommended for optimum surface finish.
