SPMT09T308-MP4 WPP20G Square 90° Turning Insert, Tiger‑tec Gold for Steel by Walter Tools

SPMT09T308-MP4 WPP20G is a coated carbide turning insert designed for productive steel machining with a square 90° form and controlled chip formation

• Tiger‑tec Gold coating for long tool life
• MP4 chipbreaker for stable chip control
• Square 90° form for versatile turning
• Optimised for steel (P) machining

High wear resistance for productive steel turning

The combination of the WPP20G grade and Tiger‑tec Gold technology delivers a coated carbide that balances wear resistance and toughness for continuous production. The designated grade is optimised for steel (material group P), which means heat and typical chip forms from steel cutting were considered during development. With the MP4 chipbreaker, the insert promotes reliable chip control, reducing interruptions and improving tool life — a tangible efficiency advantage for batch and continuous turning operations.

Geometry that ensures consistent edge engagement and finish

A square 90° plate form paired with a 0.8 mm corner radius and an 11° relief angle produces stable cutting conditions and repeatable contact geometry. This combination helps achieve uniform surface quality and predictable dimensional results across repeating parts. The tolerance class M and plate thickness T3 contribute to mechanical stability in the toolholder, reducing vibration and protecting the cutting edge during deeper cuts or interrupted machining.

Robust process security for shop-floor productivity

As a solution from Walter Tools, this insert supports process security through consistent edge behaviour and straightforward insert indexing. The SPMT09T308-MP4 WPP20G insert is particularly suitable where a balance of tool life and reliability is required in steel turning; the grade selection emphasises universal wear resistance while maintaining enough toughness to resist chipping. In practical terms, this means fewer tool changes, more predictable maintenance intervals and steady part quality — factors that lower unit costs and simplify production planning.

FAQ

What materials is this insert suited for?
The SPMT09T308-MP4 WPP20G insert is designed primarily for steel machining (material group P); the WPP20G grade and Tiger‑tec Gold coating are optimised to handle the thermal and chip‑forming conditions typical of steel.

How does the MP4 chipbreaker benefit production?
The MP4 chipbreaker on this Walter Tools turning insert improves chip control and facilitates continuous machining, which reduces interruptions and supports steady production throughput.

Which toolholder geometries are compatible with the square 90° insert?
Holders designed for square 90° inserts with the SPMT form are compatible; ensure the holder matches the SPMT09T308-MP4 seating and clamping geometry for correct engagement and stability.

Is the grade suitable for heavy interrupted cuts?
The WPP20G grade offers a compromise between wear resistance and toughness; while it provides good durability, heavy interrupted cuts should be assessed against specific cutting parameters and holder rigidity to confirm suitability.
