DCMT11T308-MP4 WPP20G Drehwendeschneidplatte – Tiger·tec Gold coating for Stahl (Walter Tools)

The DCMT11T308-MP4 WPP20G is a rhombic 55° turning insert engineered for general Stahl turning, combining Tiger·tec Gold wear resistance with a controlled chipformer for stable, repeatable machining.

• Tiger·tec Gold coating for superior wear resistance
• Optimised MP4 chipformer for reliable chip control
• Rhombic 55° form with 0.8 mm corner radius
• Designed for Stahl machining with stable edge life

Consistent productivity through advanced coating and chip control

The combination of the Tiger·tec Gold coating and the WPP20G grade delivers a measurable improvement in surface integrity and tool life when machining Stahl. The Tiger·tec Gold technology is a multilayer coating system that enhances thermal and abrasive resistance, which means longer cutting times between indexings and fewer tool changes. The MP4 chipformer is specifically shaped to break and evacuate chips reliably under the thermal and mechanical loads typical of turning operations in the P material group; this reduces tool edge wear and supports uninterrupted production runs. As a result, process stability and productivity are improved, contributing to lower unit costs and predictable cycle times.

Geometry that balances strength and surface finish

The Rhombic 55° insert geometry with a 0.8 mm corner radius provides a balanced combination of cutting-edge strength and surface finishing capability. A larger corner radius increases edge robustness and offers improved resistance to chipping during interrupted cuts, while the 55° approach angle supports good access to turned features and controlled cutting forces. The insert thickness T3 and tolerance class M ensure consistent seating and repeatable clamping, which reduces dimensional scatter between insert changes. These geometric choices translate into dependable part quality and reduced rework, especially on medium to heavy turning tasks in Stahl applications.

Application spectrum and process advantages for workshop use

Rated for the P application group, the insert is intended for unalloyed and alloyed Stahl, where typical heat generation and chip formation patterns are expected. The DCMT11T308-MP4 WPP20G is suitable for a broad range of turning operations, from roughing where edge security is critical to medium-finishing where surface quality matters. The coated carbide substrate and MP4 chip control allow for higher cutting speeds compared with conventional grades, improving throughput without compromising stability. For integrators and production planners, this offers a clear cost-benefit: reduced tool consumption per part and fewer machine interruptions. If specific cutting data are required for an application, compatibility with existing toolholders and cutting parameters can be verified quickly to shorten setup time and get production moving sooner.
