DCMT11T308-FW4 WPP20G indexable turning insert — Tiger·tec Gold coating, FW4 chipbreaker — Walter Tools

The DCMT11T308-FW4 WPP20G is an indexable turning insert designed for general steel machining, combining a Tiger·tec Gold coated carbide grade with a FW4 chipbreaker to ensure reliable chip formation and extended tool life.

• Tiger·tec Gold coated carbide for long life
• FW4 chipbreaker for reliable chip control
• Rhombic 55° form with 0.8 mm corner radius
• 7° relief angle optimised for steel machining

Extended tool life through modern coating technology

The combination of the Tiger·tec Gold coating and the WPP20G carbide class delivers a robust surface treatment that reduces wear and improves thermal resistance in continuous turning operations. This coated carbide composition is specifically developed for machining steel and adapts to the typical heat and chip formation encountered in such materials. The coating reduces flank wear and helps maintain edge stability over repeated regrinds, which translates into longer in-service intervals and lower tool consumption per component. For production environments where repeatability matters, this surface treatment supports stable machining results and predictable tool-change scheduling.

Geometry tuned for consistent chip control and surface quality

The rhombic 55° geometry, combined with a 0.8 mm corner radius and the FW4 chipbreaker, balances form strength and edge sharpness to deliver consistent chip formation and good surface finish on turned parts. The 7° relief angle assists in reducing rubbing and minimises built-up edge when machining medium to high-strength steels. The FW4 chipbreaker is engineered to control chip flow under a wide range of cutting conditions, helping to avoid long, stringy chips and reducing the risk of workpiece damage or machine downtime. This geometry is particularly useful for medium-depth finishing passes where dimensional stability and surface integrity are priorities.

Designed for reliable production performance and straightforward integration

Classified under tolerance M and produced to the DCMT ISO designation, this indexable insert fits standard toolholders compatible with the DCMT-11 form and integrates easily into existing tool assemblies. The grade WPP20G is a coated cemented carbide developed for versatile use across steel machining tasks and affords a good balance between wear resistance and toughness. The insert’s predictable behaviour under load supports process optimisation: reduced interruptions for rework, improved batch consistency and longer uninterrupted runtimes. For batch production or job-shop environments seeking dependable performance, the insert’s characteristics contribute to improved productivity and lower overall tooling costs.
