DCMT11T308-MW4 WPP20G turning insert (for Steel) – Walter Tools

The DCMT11T308-MW4 WPP20G is a rhombic 55° indexable turning insert designed for general steel machining, offering a 7° clearance angle and a Tiger·tec Gold coated carbide grade for robust performance.

• Tiger·tec Gold coating for robust wear resistance
• Optimised MW4 chipbreaker for dependable chip control
• Rhombic 55° form with 0.8 mm corner radius
• Designed for steel machining (ISO group P)

Longer tool life and consistent wear protection for steel turning

The combination of coated carbide and the Tiger·tec Gold technology provides enhanced surface hardness and heat resistance, which translates into longer tool life under typical steel cutting temperatures. The applied coating reduces abrasive wear and helps preserve the cutting edge geometry for extended production runs. For shops focused on stable performance in series turning, this insert reduces the frequency of index changes and supports predictable tool consumption. The product name appears here to identify the exact insert variant and its grade for procurement and tool assembly.

Geometry that balances strength and surface finish

A rhombic 55° shape with a corner radius of 0.8 mm and a 7° clearance angle offers a compromise between robustness and finishing capability: the geometry supports controlled cutting forces while still allowing fine surface results on turned parts. The MW4 chipbreaker is tuned for steel applications (ISO group P) and promotes regular chip segmentation, reducing the risk of long, tangled chips and improving process stability. The nominal plate size and the T3 plate thickness ensure secure clamping and repeatable positioning in standard toolholders.

Process reliability, application scope and economic benefit

With tolerance class M and a grade optimised for steel, this insert supports a wide range of general turning tasks from semi-finish to finishing, depending on machine and process parameters. The engineered chip control and coating yield lower downtime for insert changes and help maintain consistent part quality across batches. For manufacturers seeking a balance of productivity and economy, the combination of geometry and Tiger·tec Gold coating contributes to reduced overall machining costs per component and fewer unscheduled interventions.

FAQ

What materials is this insert suitable for?
The DCMT11T308-MW4 WPP20G insert is designed for machining steel (ISO group P); the WPP20G grade and Tiger·tec Gold coating are optimised for the heat and chip formation typical of steel turning.

How does the MW4 chipbreaker affect machining?
The MW4 chipbreaker promotes regular chip segmentation and improved chip evacuation on steel, supporting process reliability and reducing the risk of chip entanglement during continuous turning operations.

What does the 0.8 mm corner radius mean for part quality?
A 0.8 mm corner radius balances edge strength with surface finish: it increases edge robustness compared with smaller radii while still allowing good surface quality for general turning tasks.

Is this insert compatible with standard toolholders for DCMT geometry?
Yes; the insert follows the DCMT11T308 geometry and fits standard toolholders designed for this insert format; however, correct clamping and seat condition should be verified before first use.

What distinguishes the WPP20G grade from other grades?
WPP20G is a coated carbide grade within the Tiger·tec Gold family, tuned for wear resistance and a broad application range in steel turning; it aims to combine durability with consistent cutting-edge performance.
