SNMG120412-MP5 WPP20G — indexable turning insert, 0° negative rake, 1.2 mm corner radius (Walter Tools)

A SNMG120412-MP5 WPP20G indexable turning insert engineered for productive and reliable machining of steel components in the Tiger‑tec Gold series

• Tiger‑tec Gold coated carbide grade WPP20G
• Designed for steel machining (ISO group P)
• MP5 chipbreaker for reliable chip control
• 0° negative rake, 1.2 mm corner radius

Stable productivity and extended tool life for steel turning

The Tiger‑tec Gold WPP20G grade delivers a balance between wear resistance and toughness that suits uninterrupted production. The coating technology reduces flank wear and maintains a stable cutting edge under the high temperatures typical for steel machining, which translates into longer intervals between index changes and fewer unplanned stops. For shops seeking predictable tool life and consistent component quality, this combination supports higher productivity and lower overall machining costs.

Predictable chip behaviour and improved surface finish

The MP5 chipbreaker is designed to produce short, consistent chips in a wide range of steel alloys (ISO group P). Controlled chip formation reduces the risk of entanglement and machine downtime and helps maintain a steady cutting force, which in turn benefits the surface finish of turned parts. Explaining briefly: a chipbreaker shapes and breaks the metal shavings so they evacuate cleanly — improving process reliability without requiring extra coolant strategies.

Rigidity and repeatable accuracy from robust geometry

A 0° negative rake and a 1.2 mm corner radius provide mechanical strength at the cutting edge, making the insert particularly suited to heavier cuts and interrupted cuts where edge stability is critical. The square 90° form offers four usable cutting edges per index, enabling economical edge utilisation and straightforward seating in standard tool holders. This geometry supports repeatable dimensional accuracy on serial parts and reduces set‑up sensitivity.

Easy integration into standard turning workflows

The insert follows the common designation and sizing conventions, which simplifies ordering and toolholder selection for existing tool inventories. The grade and chipbreaker combination is versatile across many steel grades, offering shops a single insert solution for varied turning tasks. For production planning, the clear material suitability (ISO P) and known performance characteristics make process documentation and machining parameter selection more straightforward.
