The Walter Tiger-tec Gold indexable inserts enable an extension of tool life for milling applications by up to several hundred percent.

Even though Tiger-tech Gold has only been available as part of Walter's standard range since the beginning of 2017, the new coating technology for indexable inserts has already taken the market by storm, as the manufacturers report. The key to its success is the new type of coating on the indexable inserts used for milling, which features a highly wear-resistant TiAlN layer. This is applied using a low-pressure process (ULP/CVD) that has been developed in-house and reportedly minimizes typical manifestations of wear such as abrasion, deformation, hairline cracks and oxidation. As the exhibitors point out, their new indexable insert types and geometries in the milling grade WKP35G extend the range of applications to copy milling, slot milling, high-feed milling and slotting cutters. As is claimed, many users from the automotive, mold and die making and energy industries have confirmed the findings of pre-launch laboratory tests. These results apparently show an improvement of cutting parameters and tool life, with some reports even professing increases of several hundred percent.
