DCMT11T312-MP4 WPP20G indexable turning insert — Tiger·tec Gold, for steel | Walter Tools

The DCMT11T312-MP4 WPP20G is an indexable turning insert engineered for universal steel machining, combining a coated carbide grade with a dedicated chipbreaker for reliable metalworking performance.

• Tiger·tec Gold coated carbide grade WPP20G
• MP4 chipbreaker for stable chip control
• Rhombic 55° geometry with 7° clearance angle
• Corner radius 1.2 mm and size 11 for versatile turning

High-performance grade for efficient steel turning

The combination of the WPP20G grade and the Tiger·tec Gold technology delivers a balance of wear resistance and toughness tailored to steel (ISO P). The coated carbide nature of the grade reduces flank and crater wear, which extends tool life and stabilises process windows. This results in fewer insert changes and improved uptime in production environments. The specification is especially relevant where predictable tool life and consistent component quality are required, making it suitable for medium- to high-volume turning operations.

Predictable chip control and improved surface quality

Equipped with the MP4 chipbreaker and a rhombic 55° form, the insert promotes controlled chip formation during cutting, reducing the risk of entangling and facilitating safe chip evacuation. The modest 7° clearance angle supports smooth engagement with typical steel workpieces while the 1.2 mm corner radius helps achieve a balance between edge strength and surface finish. For operators unfamiliar with chipbreaker design: a chipbreaker shapes and breaks chips into manageable pieces, improving machining stability and protecting both the workpiece and the toolholder.

Practical benefits for workshop productivity

Tolerance class M and the standard T3 thickness ensure compatibility with common toolholders for DCMT-style inserts, aiding quick index changes and minimising setup time. The insert's designation reflects an ISO-compatible format that simplifies inventory and replacement planning. In practical terms, these features contribute to reduced machining interruptions and predictable process control, which supports leaner production and better cost-efficiency over time.
