SNMM190616-HU7 WPP20G indexable turning insert — Tiger·tec Gold, for Stahl | Walter Tools

The SNMM190616-HU7 WPP20G is a square 90° coated carbide turning insert from the Tiger·tec Gold series, designed for reliable finishing and medium-duty turning of Stahl.

• Tiger·tec Gold coated carbide
• Optimised for turning Stahl
• Square 90° insert, 19 mm size
• HU7 chipbreaker for controlled chips

Durable Tiger·tec Gold coating for longer productive runs

The Tiger·tec Gold technology and the WPP20G coated carbide deliver a tangible increase in resistance to abrasive wear and thermal loading during Stahl turning. Coated carbide grades combine a hard substrate with multilayer surface treatments to slow flank and crater wear; this results in longer tool life and fewer index changes on the turret, which directly reduces downtime. For production environments this means more consistent cycle times and a measurable improvement in tool-change intervals.

Geometry and chip control that stabilise the machining process

A square 90° shape with a 1.6 mm corner radius and the HU7 chipbreaker create a stable cutting geometry that supports predictable chip formation and surface finish. The 0° (negative) relief angle increases edge strength for interrupted cuts and heavy cross‑sections, while the medium tolerance class M ensures repeatable seating in standard toolholders. The chipbreaker design guides chips away from the cutting edge to avoid entanglement; in practice this reduces rework, protects the workpiece surface and improves swarf evacuation in blocked coolant situations.

Practical benefits for workshops and CNC turning centres

Specifically intended for Stahl applications, the insert’s specifications (19 mm size, designation 06 thickness) allow easy integration into common insert pockets and turning systems. The combination of coated substrate and robust edge geometry supports both roughing passes with improved edge life and finishing passes with reliable surface quality. For shops aiming to increase throughput, this insert offers a cost‑efficient balance of durability and process stability, while the ISO designation aids straightforward tool planning and inventory management. The SKU and series information assist in selecting the matching grade for existing holders and cutters.

FAQ

Which materials can this insert machine effectively?
The SNMM190616-HU7 WPP20G is formulated for machining Stahl (ISO group P); the WPP20G grade and Tiger·tec Gold coating are optimised for the temperatures and chip formation typical of Stahl cutting.

How does the HU7 chipbreaker improve the turning process?
The HU7 chipbreaker on this square insert promotes controlled chip formation and guided evacuation, reducing chip re-cutting and helping to maintain surface quality and tool life during continuous turning operations.

Is the insert suitable for interrupted cuts or heavy cross‑sections?
Yes; the 0° (negative) relief and robust edge geometry increase edge strength, making the insert appropriate for interrupted cuts and instances where increased edge toughness is required.

How does the corner radius affect finish and tool life?
The 1.6 mm corner radius balances edge strength and surface finish: it supports higher feed rates and greater durability than a smaller radius while still providing acceptable finish for general turning tasks.
