Indexable turning insert CNMM120412-HU5 WMP20S (Rhombic 80°, Walter Tools) for rostfreier Stahl

CNMM120412-HU5 WMP20S is a compact indexable insert optimised for turning rostfreier Stahl under mid to robust cutting conditions, combining a coated carbide grade with a chipbreaker designed for secure chip control.

• Tiger·tec Silver coating for rostfreier Stahl machining
• Stable chip formation with HU5 chipbreaker
• Rhombic 80° geometry with 1.2 mm corner radius
• 0° negative rake for secure cutting edge support

Consistent machining performance with modern coating technology

The Tiger·tec Silver coating, combined with the WMP20S coated carbide grade, is formulated specifically for the demands of rostfreier Stahl. The coating improves thermal resistance and reduces adhesion tendencies that commonly cause build-up on the cutting edge; as a result the insert maintains a stable cutting edge over longer cycles, reducing interruption for tool changes. This leads to measurable improvements in process reliability and component consistency, particularly when machining tough, tendency-to-stick stainless alloys. The result is more predictable throughput and fewer rejects in series production.

Geometry and chip control that improve productivity

Designed in a rhombic 80° shape with a 1.2 mm corner radius and a HU5 chipbreaker, the insert balances strength and accessibility. The rhombic geometry provides a secure support face for heavier cuts while still allowing access to tighter profiles, and the specified corner radius supports edge robustness without sacrificing surface finish. The negative rake 0° angle enhances edge support for interrupted cuts and prevents premature chipping in demanding rostfreier Stahl applications. Together these features simplify setup choices and contribute to consistent cycle times on lathes and turning centres.

Practical benefits for workshop efficiency and process security

This grade and geometry combination is aimed at production environments that require repeatable results and minimum downtime. The WMP20S sort supports stable chip formation in rostfreier Stahl, reducing the risk of built-up edge and improving surface integrity on finished parts. For procurement and process planning the CNMM format offers a straightforward, widely compatible solution for standard toolholders, making inventory management and tool-change procedures more efficient. Relying on a recognised cutter brand such as Walter Tools adds the assurance of thorough material characterisation and consistent batch quality.

FAQ

What materials is this insert suitable for?
The CNMM120412-HU5 WMP20S insert is formulated for machining rostfreier Stahl; the WMP20S grade and Tiger·tec Silver coating promote stable chip formation and reduced build-up when cutting stainless alloys.

How does the HU5 chipbreaker affect performance?
The HU5 chipbreaker on this Walter Tools insert supports controlled chip formation in rostfreier Stahl, which helps maintain surface quality and reduces the likelihood of entangling or long, stringy chips.

Is the rhombic 80° shape suitable for interrupted cuts?
Yes; the rhombic 80° geometry combined with the 0° negative rake provides enhanced edge support, making the insert well suited for intermittent engagement and applications requiring robustness.

Can this insert be used on standard CNMM toolholders?
The CNMM120412-HU5 format is compatible with standard holders designed for that ISO family; verify holder specification and clamping method for correct seating and secure fixation.

What are the expected workshop benefits when switching to this grade?
Adopting the WMP20S grade in Tiger·tec Silver typically improves process stability for rostfreier Stahl, reduces unscheduled tool changes due to built-up edge and supports more consistent part quality.
