SCMT09T304-MP4 WPP20G square turning/drilling insert by Walter Tools — Tiger·tec Gold, MP4 chipbreaker, 7° clearance

SCMT09T304-MP4 WPP20G is a square indexable insert designed for turning and boring applications on Stahl, combining a Tiger·tec Gold coating with a robust chipbreaking geometry for reliable production performance.

• Tiger·tec Gold coating for extended life
• WPP20G grade optimised for Stahl machining
• MP4 chipbreaker for reliable chip control
• 7° clearance and 0.4 mm corner radius

Extended tool life through an advanced grade

The insert is produced in the Tiger·tec Gold series and uses the WPP20G grade, a coated carbide formulation that balances wear resistance and toughness for machining Stahl. This combination reduces crater and flank wear under the thermal and mechanical loads typical of steel turning, which translates into longer service intervals and fewer tool changes. The coating adheres to the substrate and reduces built-up edge; as a result, process stability is improved and surface quality is more consistent.

Predictable chip control for smooth production

Equipped with the MP4 chipbreaking geometry, the insert delivers controlled chip formation in a wide range of turning and boring conditions. The chipbreaker design breaks and ejects chips reliably, reducing the risk of entanglement and leaving a steady cutting load on the tool. This predictable behaviour minimises downtime caused by chip-related incidents and supports continuous operation on automated or unattended machines, while also helping to maintain a repeatable surface finish.

Geometry tuned for dimensional consistency

The square 90° form with 7° clearance and a 0.4 mm corner radius provides a good balance between strength and finishing capability. The T3 plate thickness and tolerance class M ensure rigid seating in the toolholder and repeatable positioning, which is essential for tight tolerances and batch-to-batch consistency. A smaller corner radius supports finer surface finish where required, while the 90° shape enables robust turning and light profiling without sacrificing stability.

Practical application and productivity gains

Intended as an indexable insert for both drilling/boring and turning tool families, this design supports flexible machining strategies where one carbide grade can cover a variety of operations on Stahl. By standardising on a single, universal grade like WPP20G, tool inventories are simplified and tool-change frequency is reduced, which positively impacts overall equipment effectiveness. The insert’s combination of coating and geometry is geared towards sustaining throughput while maintaining predictable tool life.

FAQ

What materials is this insert intended for?
The SCMT09T304-MP4 WPP20G insert is specified for the ISO P group and is intended for machining Stahl (unalloyed and alloyed steels).

How does the MP4 chipbreaker affect machining?
The MP4 chipbreaker on this Walter Tools insert promotes short, controllable chips and consistent cutting forces, which reduces downtime and improves surface quality during turning and boring.

What advantage does the Tiger·tec Gold coating offer?
The Tiger·tec Gold coating on the WPP20G grade increases wear resistance and thermal stability, extending tool life and supporting more stable production cycles on Stahl components.

Which geometrical features support accurate workpiece tolerances?
The square 90° form combined with a 7° clearance and a 0.4 mm corner radius ensures rigid seating and repeatable tool engagement, aiding dimensional accuracy in serial production.

Is this insert compatible with both turning and boring holders?
Yes, the product type indicates suitability for both turning and drilling/boring insert systems; verify holder compatibility with the SCMT09T304-MP4 designation for correct seating and clamp fit.
