SNMM150612-HU5 WMP20G indexable turning insert (square 90°, r1.2) – Walter Tools

The SNMM150612-HU5 WMP20G is a square 90° indexable turning insert engineered for medium to robust turning of stainless steel, offering a Tiger·tec Gold coated carbide grade and a HU5 chipbreaker for controlled cutting.

• Tiger·tec Gold coated carbide for stainless steel
• Square 90° insert with 1.2 mm corner radius
• HU5 chipbreaker for reliable chip control
• 0° negative rake for secure cutting action

Consistent performance for stainless steel machining

The combination of the Tiger·tec Gold coating with the WMP20G carbide grade produces a balance of wear resistance and thermal stability that benefits turning operations in stainless steel (ISO M). The coating technology reduces adhesive wear and supports a stable cutting edge under elevated temperatures and the tough, work-hardening tendencies typical of stainless steel. The HU5 chipbreaker is designed to shape and break chips reliably, lowering the risk of built-up edge and improving process security during medium to heavy cuts. By stabilising chip formation and protecting the edge, this configuration helps to extend tool life and reduce unscheduled tool changes, contributing to a smoother production flow and predictable cycle times.

Geometry and robustness that protect productivity

The square 90° geometry with a 1.2 mm corner radius delivers a robust cutting edge suited to heavier depth-of-cut work, while the 0° negative rake provides a secure cutting action that resists edge chipping in interrupted cuts. These geometric choices mean fewer insert indexing cycles and stronger resistance to mechanical shock. For operations where edge stability and repeatability matter, the insert’s design offers a pragmatic solution: larger corner radii distribute cutting forces, minimise local overheating and blunt wear, and permit higher metal removal rates without compromising dimensional stability. The insert thickness designation supports clamping stability in standard toolholders, further enhancing process reliability in production environments.

Practical benefits in everyday production

Incorporating this insert into a toolset translates into practical advantages: improved cycle consistency, lower tooling consumption per part, and reduced downtime for insert changes. The HU5 chip control, combined with the Tiger·tec Gold coating, supports continuous chips or segmented chips according to cutting data and material condition, which simplifies chip handling in automated cells. For shops aiming to balance productivity and reproducible surface finish on stainless steel components, this grade provides a clear efficiency argument: fewer rejects, longer intervals between tool interventions and stable surface quality under repeatable cutting conditions. For specific feeds and speeds, refer to machine and workpiece rigidity parameters; the insert’s properties allow conservative starting values to be increased safely once stability is proven.

FAQ

Which materials is the SNMM150612-HU5 WMP20G best suited for?
The SNMM150612-HU5 WMP20G indexable turning insert from Walter Tools is formulated for stainless steel (ISO M), where its coating and chipbreaker support secure chip formation and edge stability under the material’s tendency to work-harden.

What is the function of the HU5 chipbreaker on this insert?
The HU5 chipbreaker on the SNMM150612-HU5 WMP20G guides and fractures chips to reduce stringing and improve evacuation, which helps maintain consistent cutting conditions and protects the cutting edge during longer runs.

How does the 1.2 mm corner radius influence cutting performance?
A 1.2 mm corner radius increases edge strength and distributes cutting forces, making the insert better suited to medium and heavy cuts; it helps reduce chipping and extend insert life compared with smaller radii.

Is this insert suitable for interrupted cuts or heavy roughing operations?
Yes, the square 90° geometry combined with the 0° negative rake and the robust Tiger·tec Gold coated grade offers good resistance to impact and edge damage, making the insert appropriate for interrupted cuts and demanding roughing tasks.
