SCMT120408-MP4 WPP20G — Square 90° indexable insert, Tiger‑tec Gold for steel | Walter Tools

The SCMT120408-MP4 WPP20G is a square 90° coated carbide insert from Walter Tools, engineered for efficient turning and boring of steel components.

• Tiger‑tec Gold coating for extended life
• Optimised MP4 chipbreaker for steel machining
• Square 90° form for four usable edges
• 0.8 mm corner radius for edge strength

Increased productivity for steel turning with Tiger‑tec Gold

The coated carbide grade Tiger‑tec Gold in this insert ensures improved wear resistance and stable cutting under the heat and stress typical of steel machining. The WPP20G composition is engineered for a balance of wear resistance and toughness, which reduces edge breakdown during medium-to-high cutting conditions. As a result, the tool life is extended and process stability is improved, supporting predictable cycle times and fewer index changes on the toolholder.

Predictable chip formation and surface quality

The dedicated MP4 chipbreaker is optimised for ISO P materials, promoting consistent chip breaking and evacuation during interrupted and continuous cuts. This controlled chip behaviour lowers the risk of workpiece damage and easing swarf handling in production environments. The insert geometry supports a reliable surface finish, allowing higher productivity without sacrificing dimensional quality on turned components.

Geometry engineered for strength and repeatability

With a square 90° plate form and a 0.8 mm corner radius, the insert combines four indexable cutting edges with sufficient edge support to resist chipping. The 7° relief angle provides adequate clearance while maintaining cutting stability. These geometric choices result in robust performance when facing common turning tasks, reducing the frequency of edge failure and maintaining repeatable results in batch production.

Practical fitment and application range

The insert is supplied in size 12 with thickness 04, tolerance class M, and is designated for the material group P (steel). This specification makes the insert suitable for a wide range of steel grades, offering a universal solution for many workshop turning and boring applications. The combination of coating, chipformer and geometry translates into fewer tool changes and more uptime on the machine.
