CCMT120408-MP4 WPP20G – Turning and Boring Indexable Insert, Tiger·tec Gold, Walter Tools

The CCMT120408-MP4 WPP20G is a coated carbide turning and boring indexable insert engineered for efficient steel machining with a rhombic 80° geometry.

Tiger·tec Gold coated grade WPP20G
Optimised MP4 chipbreaker for steel
Rhombic 80° geometry with 0.8 mm radius
7° clearance angle for stable cutting

Longer tool life from advanced coating technology

The Tiger·tec Gold coating on this grade provides a balanced combination of wear resistance and toughness, optimised for cyclic thermal loads encountered when machining steel. The coated carbide substrate maintains edge stability under medium to high cutting stresses, reducing flank wear and delaying the need for index changes. For production environments this translates into fewer interruptions and more predictable tool-change intervals, improving overall machining throughput and lowering unit costs.

Geometry tuned for consistent chip control and surface quality

A rhombic 80° insert form with a 0.8 mm corner radius and 7° clearance angle delivers a reliable cutting edge for turning and boring operations. The MP4 chipbreaker is tailored for chip control in unalloyed and alloyed steels, producing short, controlled chips that evacuate reliably in common setups. The combination of edge form and chipbreaker supports stable cutting forces and helps to maintain consistent surface finish and dimensional repeatability across workpieces.

Stable process performance for workshop productivity

Built for repeatable results, this indexable insert benefits shops that prioritise process security and efficient cycle times. The WPP20G grade is designed for a broad steel range, offering robust performance in mixed-lot production where material grades vary. Less time spent on tool adjustments and fewer rejects contribute to improved shop-floor efficiency and a stronger return on tooling investment, while modern coating technology helps maintain a consistent edge life under varying cutting conditions.

Clear application scope and material compatibility

This insert is specified for the machining of steel according to ISO 513 classifications; it is optimised for the heat and chip-formation characteristics typical of steel turning. The insert’s geometry and grade make it suitable for general turning and boring tasks in production environments where a balance of wear resistance and toughness is required. For operations requiring different material groups, selection of a purpose-matched grade is advised to preserve performance and tool life.
