Extend tool life with advanced Tiger·tec Gold coating

The combination of Tiger·tec Gold coating and coated carbide substrate delivers enhanced wear resistance and consistent edge stability under typical turning loads. This technology is designed to reduce flank wear and maintain cutting-edge integrity over longer tool cycles, resulting in fewer indexings and reduced tool costs. The grade WPP20G is optimised for Stahl machining, where thermal load and chip formation demand a coating that manages heat and abrasion effectively. For operations prioritising uptime and predictable replacement intervals, the coated grade supports high process reliability.

Achieve precise finishes thanks to optimised geometry

The insert’s rhombic 35° geometry and 1.2 mm corner radius combine to produce controlled cutting engagement and repeatable surface quality. A smaller corner radius enables fine finishing passes while preserving edge strength for light interrupted cuts. The MP5 chipbreaker is tailored to the insert size and geometry, guiding chip flow and reducing the risk of built-up edge. Together, these features support consistent part quality and minimise secondary operations, so finishing tolerances can be achieved with fewer passes.

Improve cycle times with stable chip control

Chip management directly influences machining efficiency. The MP5 chipbreaker promotes short, segmented chips when turning Stahl, reducing re-cutting and easing evacuation from the cutting zone. Stable chip formation lowers the likelihood of tool interruptions and helps maintain recommended cutting parameters for longer stretches. In practice, this leads to higher effective throughput and a more predictable production rhythm, particularly in batch and serial turning where small gains per part accumulate into notable productivity improvements.

Application range and material guidance for confident selection

This insert is specified for the ISO group P and is suitable for a broad spectrum of Stahl grades commonly encountered in general turning. The VNMG160412-MP5 WPP20G performs best where a balance of wear resistance and toughness is required, making it appropriate for both continuous cuts and light interruptions. For optimal results, select feed and speed parameters in line with Walter Tools’ recommendations for the WPP20G grade and the intended material subgroup; this approach ensures the coating and substrate deliver the promised service life and surface integrity.
