CCMT120404-MW4 WPP20G — Turning insert, Tiger‑tec Gold by Walter Tools

A Walter Tools CCMT120404-MW4 WPP20G turning insert designed for efficient steel machining, combining Tiger‑tec Gold coating with a MW4 chipbreaker for stable, repeatable cutting.

• Tiger-tec Gold coating for long tool life
• Optimised chip control with MW4 breaker
• Rhombic 80° form, 0.4 mm corner radius
• 7° relief angle for stable cutting performance

Consistent performance through optimised coating and grade

The combination of the Tiger‑tec Gold coating and a coated carbide substrate is engineered to resist abrasion and thermal stress during turning operations. As a grade intended for group P (steel), the insert is optimised for the heat and chip-formation behaviour typical of unalloyed and alloyed steels according to ISO classification. This results in longer tool life and fewer tool changes, which lowers downtime and increases productive cutting time on batch and serial production.

Geometry and edge design for reliable surface quality

The rhombic 80° form, 0.4 mm corner radius and 7° relief angle together provide a balance between strength and accessibility for medium-duty turning. The MW4 chipbreaker promotes controlled chip flow and reduces the risk of built-up edge, supporting consistent surface finish and dimensional stability. The insert’s tolerance class M ensures interchangeability and predictable seating in standard toolholders, simplifying tool set-up and repeatable results across machines.

Practical application and process benefits for workshop use

This indexable insert is suitable for finishing and general turning in steels where balanced wear resistance and toughness are required. The grade WPP20G is positioned as a versatile choice within the Tiger‑tec Gold family, offering predictable performance across a range of steels. Reduced flank wear and improved edge security enable stable cutting parameters and more consistent component quality. For process optimisation, pairing this insert with appropriate speeds, feeds and coolant strategy will unlock the best compromise between removal rates and surface integrity.
