CNMM160612-HU5 WMP20G — Rhombic 80° indexable insert, Tiger·tec Gold (Walter Tools)

The CNMM160612-HU20G WMP20G is a rhombic 80° indexable turning insert engineered for demanding stainless-steel machining with a focus on secure chip formation and repeatable tool life.

• Tiger·tec Gold coated grade WMP20G
• Optimised chip control HU5 chipbreaker
• Rhombic 80° geometry for versatile turning
• Corner radius 1.2 mm for stable cutting

High repeatability and process security for stainless-steel turning

The coated carbide grade WMP20G in the Tiger·tec Gold series combines a wear-resistant surface with a substrate designed for thermal resilience, delivering stable cutting edges when machining stainless steel. The rhombic 80° geometry provides a balanced cutting face and good access for a range of turning operations, while the negative 0° rake increases robustness in interrupted cuts. These design choices reduce the tendency for edge build-up and support predictable component tolerances in series production.

Predictable chip control and extended tool life

Equipped with the HU5 chipbreaker, the insert promotes controllable chip formation across moderate to robust cutting parameters. The optimised chip flow reduces re-cutting of chips and diminishes heat concentration at the cutting zone, which in turn supports longer effective life of the insert and more stable surface quality on turned parts. The Tiger·tec Gold coating enhances abrasion resistance and helps to maintain a reliable cutting edge under higher temperatures typical for austenitic stainless steels.

Geometry that improves on-machine performance

The rhombic plate shape with a 1.2 mm corner radius combines strength at the cutting edge with a geometry that suits both finishing and semi-finishing passes. The 06 thickness code and the plate form enable secure clamping in standard toolholders while the negative 0° free angle promotes chip evacuation and reduces sensitivity to workpiece build-up. These features translate into fewer unscheduled tool changes and improved uptime on turning centres.

Application scope and economic advantage in production

Designed specifically for machining rostfreier Stahl (stainless steel) under medium to robust conditions, the insert supports consistent part quality and reduced scrap rates. Its combination of coating technology and chipbreaker design leads to a favourable cost-per-part in batch production. For process planners, the predictable behaviour of this grade simplifies parameter selection and tool lifecycle planning, contributing to steady productivity in mixed-production environments.

FAQ

What materials is this insert designed for?
The CNMM160612-HU5 WMP20G insert is specified for machining stainless steel and is optimised for the M material group, offering secure chip formation on austenitic and similarly tough stainless grades.

How does the Tiger·tec Gold series affect tool life?
The Tiger·tec Gold coating on this grade improves wear resistance and thermal stability, which helps to extend effective edge life under elevated temperatures commonly encountered when turning rostfreier Stahl.

Which chipbreaker is applied and what is its benefit?
The HU5 chipbreaker supports controlled chip formation for medium to robust cutting parameters, reducing the risk of long, tangled chips and promoting stable surface finish.

What does the 0° (negative) free angle mean for machining?
A 0° negative free angle increases edge robustness and reduces sensitivity to built-up edge during interrupted cuts, making the insert suitable for tougher turning conditions.

Is this insert suitable for automated turning centres?
Yes — the rhombic 80° geometry, standard thickness code and secure clamping characteristics make the insert suitable for use in CNC turning centres where repeatability and predictable tool life are important.
