SCMT09T308-MP4 WPP20G indexable insert — Tiger·tec Gold coating, MP4 chipformer, for steel — Walter Tools

The SCMT09T308-MP4 WPP20G is an indexable insert designed for drilling/boring and turning operations, optimised for ISO P (steel) machining where controlled chip formation and long tool life are essential.

• Tiger·tec Gold coating for coated carbide
• MP4 chipformer for stable chip control
• 0.8 mm nose radius for reliable surface finish
• Optimised for ISO P (steel) applications

Greater productivity through optimised coating and geometry

Thanks to the Tiger·tec Gold coating and the WPP20G grade, this insert delivers improved wear resistance and consistent cutting performance when machining steel. The combination of a coated carbide substrate and a modern coating system reduces flank wear and supports higher cutting parameters, which in turn raises throughput. The MP4 chipformer is engineered to break and evacuate chips predictably, reducing interruptions and machine idle time. These technical choices translate into measurable gains in cycle time and process stability for production-focused workshops.

Predictable surface quality and dimensional control

A 0.8 mm nose radius and a square 90° insert form ensure a stable cutting edge geometry that helps achieve consistent surface finish and dimensional repeatability. The 7° relief angle contributes to a predictable cutting force and favourable engagement with the workpiece, especially in interrupted cuts or when plunge-turning. Such geometric parameters mean fewer rework cycles and less reliance on manual correction, supporting both quality targets and shop-floor efficiency.

Application focus: steel machining with ISO P compatibility

The grade is specified for steel under ISO P; the insert is therefore suited to a wide range of unalloyed and alloyed steels commonly encountered in industrial parts production. Coated carbide combined with the specified chipbreaker provides good thermal stability and controlled chip flow during medium to high cutting speeds. For operations prioritising repeatable results in steel, the insert offers a robust balance between wear resistance and toughness, helping to avoid premature edge chipping while maintaining productivity.

Handling, tool life and integration into existing toolchains

The insert is available in size 09 with a T3 thickness and mounting execution T, enabling straightforward integration into standard toolholders that accept the SCMT09T308-MP4 form factor. Its tolerance class M reflects machining-grade accuracy suitable for general turning and boring tasks. Selection of this insert supports longer tool life and fewer index changes, reducing downtime and simplifying inventory management for workshops that process steel components regularly.
