SNMM250924-HU5 WMP20G – square turning indexable insert for stainless steel (Tiger·tec Gold) by Walter Tools

The SNMM250924-HU5 WMP20G is a square turning insert designed to provide stable cutting edges and reliable chip formation when machining stainless steels in medium to demanding conditions.

• Tiger·tec Gold coated carbide for stainless steel
• Square 90° insert, 25 mm edge length
• Corner radius 2.4 mm for robust edge strength
• HU5 chipbreaker for consistent chip control

Consistent cutting performance and wear resistance

The coated carbide grade WMP20G, applied using Tiger·tec Gold technology, delivers a balance of wear resistance and toughness that is tailored to the demands of stainless steels. The coating reduces adhesion and thermal load at the cutting zone, which in turn limits built-up edge and preserves the cutting geometry for longer tool life. This results in fewer index changes and a more predictable tool lifecycle, supporting continuous production and reduced tooling costs. The design is optimised to maintain a stable cutting edge even under interrupted cuts.

Process reliability through geometry and chip control

A square 90° shape combined with a HU5 chipbreaker provides secure chip formation and easy indexing for repeatable operations. The negative 0° free angle contributes to edge robustness under heavier engagement, while the 2.4 mm corner radius increases strength at the insert tip for roughing and semi-finishing passes. Together these features enhance process stability, allowing higher metal removal rates with controlled surface condition and less risk of unexpected edge failure. The insert form is therefore suited to a range of turning tasks where reliability is a priority.

Application suitability and machining behaviour

This insert targets ISO group M applications and is optimised for stainless steels, which are known for toughness and a tendency to form adhesions on the tool. The WMP20G grade promotes secure chip breaking and heat management; it is particularly effective in medium to robust cutting regimes where consistent chip flow and edge life are required. For component manufacturers working with austenitic and other common stainless grades, the insert reduces the need for frequent tool intervention and helps to maintain dimensional stability across batches.

Practical integration and economic benefits

The SNMM250924-HU5 WMP20G fits standard toolholder systems for square 90° inserts, enabling straightforward replacement and quick indexing. Because of the coated carbide’s extended wear resistance and the proven HU5 chip control, the insert contributes to lower tooling consumption and less downtime. This combination of Tiger·tec Gold coating and robust geometry supports repeatable results and a higher level of process security on the shop floor, making it a sound choice for production-focused turning applications using stainless steels.

FAQ

Is this insert suitable for machining stainless steels?
Yes. The SNMM250924-HU5 WMP20G insert is developed for ISO group M and is optimised for machining stainless steels under medium to robust cutting conditions.

What benefits does the Tiger·tec Gold coating bring?
The Tiger·tec Gold coating on the WMP20G grade improves wear resistance and reduces adhesion, which helps to prevent built-up edge and extend the effective cutting life of the insert.

How does the HU5 chipbreaker affect chip control?
The HU5 chipbreaker produces short, controllable chips and supports consistent chip evacuation, contributing to process stability and safer turning operations.

Can the insert withstand interrupted cuts and heavier engagements?
Yes. The negative 0° free angle and a 2.4 mm corner radius provide enhanced edge strength suitable for interrupted cuts and heavier cutting conditions.
