SNMM190612-HU5 WMP20S indexable turning insert (square 90°, for stainless steel) by Walter Tools

SNMM190612-HU5 WMP20S is a square 90° indexable turning insert designed for dependable metalcutting of stainless steels in medium to robust conditions, combining coated carbide performance with controlled chip formation.

• Tiger‑tec Silver coating for improved wear resistance
• Optimised chip control with HU5 chipbreaker
• Square 90° form, 1.2 mm corner radius
• Negative 0° rake for robust cutting stability

Consistent performance on stainless steel for predictable results

The coated carbide grade WMP20S in the Tiger‑tec Silver family delivers a balance between wear resistance and toughness that is tailored to the demands of stainless steel. The combination of the HU5 chipbreaker and the insert’s geometry supports stable chip formation under higher heat and adhesive tendencies typical of these alloys. This results in fewer unexpected interruptions, improved process reliability and a clearer basis for selecting cutting conditions in production.

Increased productivity through reduced tool changes and reliable edges

A square 90° insert form provides a strong cutting edge and multiple indexed corners, increasing usable edge life before replacement. The 1.2 mm corner radius absorbs cutting forces and reduces edge chipping in interrupted or roughing operations, while the 0° (negative) rake delivers a robust approach to heavy feeds. Together these characteristics reduce downtime and contribute directly to a better cost-per-part ratio in batch and continuous turning operations.

Easier machining setup and repeatable quality

The insert’s consistent geometry and the Tiger‑tec Silver coating make process planning more straightforward: the WMP20S grade gives predictable wear patterns and improved surface finish stability without complex parameter experimentation. For engineers and shop planners, this means fewer trial cuts, clearer specifications for tooling lists and greater confidence in repeatable surface quality across series production. The insert is especially suited for applications where secure chip control and edge stability are priorities.

FAQ

What materials is the insert suitable for?
The SNMM190612-HU5 WMP20S is designed primarily for stainless steel applications (ISO group M) and supports medium to robust cutting conditions.

How does the HU5 chipbreaker help in production?
The HU5 chipbreaker provides controlled chip formation for sticky, heat-prone materials, improving evacuation and reducing the risk of built-up edge when machining stainless steel.

What benefit does the 1.2 mm corner radius offer?
A 1.2 mm corner radius increases edge strength and dampens cutting shocks, helping to avoid premature chipping during interrupted cuts or heavier feed rates.

Is the negative 0° rake suitable for roughing operations?
Yes, the 0° (negative) rake delivers a robust edge orientation that is advantageous for aggressive feeds and interrupted cutting, offering greater cutting stability.

How many indexed corners does the square insert provide?
The square 90° form offers multiple usable corners per insert, extending overall indexable edge life and contributing to cost-effective tool utilisation.
