With the new Tiger·tec® Gold PVD grade WSP45G, Walter AG is introducing a cutting tool material that really pushes the boundaries of these coatings: both in their application and with respect to the materials that the machinist can work with them. In addition to their compatibility with Xtra·tec® XT, Walter BLAXX and M4000 milling cutters, the new Tiger·tec® Gold PVD indexable inserts can also be used in Walter indexable insert drills such as the D4120; and that's not only for ISO P steels, but also for difficult-to-cut materials from the ISO S and M material groups. The multilayer coating system is the only one of its kind in the world: A TiAlN-Al2O3 multilayer makes the WSP45G both hard and tough – and therefore tremendously resistant to abrasive wear and high temperatures. A special mechanical post-treatment improves hairline crack performance and protects the cutting edge from micro-spalling. The light gold-coloured top coat 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 exhaust the full potential of the indexable insert.
Potential fields of application for the new Tiger·tec® Gold PVD grade include demanding machining tasks, such as materials with difficult cutting properties, tricky conditions and interrupted cuts. In the case of milling, these challenges could also be long overhangs or delicate clamping arrangements; with drilling, inclined entries and exits. Depending on the material and application, the new Tiger·tec® Gold PVD grade achieves performance improvements of up to 75 percent. For turbochargers in cast steel, fasteners and chassis parts in titanium or components in nickel-based alloys as encountered in the automotive, energy and aerospace industries, the WSP45G grade is an ideal problem solver.
