CPMT09T304-MP4 WPP20G turning insert — Tiger‑tec Gold, MP4 chipbreaker (Walter Tools)

The CPMT09T304-MP4 WPP20G is a rhombic 80° turning insert optimised for steel machining, offering a Tiger‑tec Gold coated grade for reliable, high‑volume production.

*Tiger‑tec Gold coated for long tool life
*WPP20G grade for steel machining
*MP4 chipbreaker for stable chip control
*Rhombic 80° form with 0.4 mm radius

Steady productivity through wear‑resistant coating

The combination of the Tiger‑tec Gold coating and the WPP20G carbide grade delivers a dependable balance between wear resistance and toughness for steel applications. Designed for the thermal and mechanical demands of machining steel, the insert maintains edge integrity over extended cycles, reducing tool changes and maintaining production throughput. The coated substrate gives consistent performance across mixed production runs where thermal fluctuation and variable cutting forces occur.

Geometry that improves process reliability

The rhombic 80° insert form and an 11° free angle provide stable engagement and predictable turning behaviour on shoulder and profiling operations. The modest 0.4 mm corner radius supports medium‑finish passes while lowering the risk of edge chipping under interrupted cuts. Combined with the MP4 chipbreaker, these geometric choices ensure controlled chip formation and smooth evacuation, which enhances cycle time stability and lowers the likelihood of workpiece damage.

Grade and chipbreaker explained for planners

The WPP20G grade is a coated carbide solution optimised for steel (ISO group P), offering a universal balance that favours wear resistance without sacrificing toughness. The MP4 chipbreaker is tuned to produce short, clearable chips in typical steel turning operations; this reduces the requirement for additional chip‑control devices and simplifies fixture planning. For production engineers, this means fewer unplanned stops and more reliable batch completion rates.

Practical handling and integration in workshops

With a standard ISO form and the designation aligned to the CPMT family, the insert fits common turning toolholders that accept CPMT‑series parts, easing inventory management. The T3 plate thickness and the specified size help maintain rigidity in the cutting edge when mounted in suitable clamping systems. For workshops seeking a practical, economically efficient solution for steel turning, the insert offers straightforward adoption and repeatable results that support lean manufacturing goals.
