Walter Tiger·Tec Gold turning grades designed for high alloy-high tensile strength steels

Walter has introduced its Tiger·Tec Gold WKP01G and WPP05G grades designed for turning high alloy-high tensile strength steels. The turning inserts reduce machining time from 20 to 30 per cent, according to the company.

The WKP01G was designed for finishing high tensile steel and cast iron (ISO P01 and K01 workpiece groups) at the highest cutting speed. A hard substrate provides flank wear resistance, while the multiple-stage post-treatment process produces an extremely smooth rake face. A sharp cutting edge with thinner CVD coating provides precise chip breaking for finishing operations.

The WPP05G grade is for medium and rough turning of steels at the maximum cutting speed. The substrate is made of a carbide with the highest hot hardness, making the insert suitable for both dry and wet-machining, and crater and flank wear resistance.

Both grades feature the Tiger·Tec Gold coating technology. The multiple-layer medium-temperature titanium carbo-nitride (MT-TiCN) coating improves the elastic property of the highly aligned crystals. In addition, the coating on the WPP05G grade has a highly textured aluminum oxide (Al2O3) coating to minimize crater wear.

Both grades are ideal for continuous cutting and occasional interrupted cuts in high tensile materials (approx. 280-410 HB or 130-200 ksi). The grades come in around 130 inserts with 11 different geometries.
