New Walter Tiger·tec® Gold PVD grade for milling and drilling expands what a cutting grade can do

Tuesday 16 February 2021, 2:28 PM

New Tiger·tec® Gold PVD grade WSP45G from Walter pushes the boundaries of what a cutting tool material can be expected to do, both in terms of applications and with respect to the materials it can efficiently process. In addition to the compatibility of WSP45G inserts with all standard milling cutters in the Walter lineup, including Xtra·tec® XT, Walter BLAXX and M4000 milling cutters. Further the new Tiger·tec® Gold PVD indexable inserts can also be used in Walter indexable insert drills such as the D4120 for ISO P steels, but also for difficult-to-cut materials from the ISO S and M material groups.

The unique TiAlN-Al2O3 multilayer coating system makes the WSP45G both hard and tough, and thus extremely resistant to abrasive wear and high temperatures, with controlled residual stresses and less flank wear, all boosting tool life. A special mechanical post-treatment improves hairline crack performance and protects the cutting edge from micro-spalling. The light gold-colored topcoat of the multilayer system makes it easier to detect wear and thereby improves process reliability. Unused cutting edges are reliably identified, making it possible to utilize the full potential of the indexable insert and further extending tool life.

Fields of application for the new Tiger·tec® Gold PVD grade include demanding machining tasks, such as materials with difficult cutting properties and interrupted cuts. Depending on the material and application, the new Tiger-tec® Gold PVD grade achieves performance improvements of up to 75 percent. In areas of use such as automotive, energy and aerospace industries, the WSP45G grade is an ideal problem solver.
