Walter has expanded the Xtra·tec XT M5008 high-feed milling cutter with the addition of the G67 geometry designed specifically for the cutter’s indexable inserts when machining heat-resistant super alloys and stainless steel (ISO S and M materials groups). The G67 geometry has a highly positive rake angle to exert low machining forces and a sharp geometry for reduced built-up edges. The geometry is also suitable for milling steel (ISO P material group).
The geometry is available in grades WSM35G, WSP45G, and WSM45X. The milling cutter accepts double-side indexable inserts with four curved cutting edges for maximum stability. The rhombic basic shape of the inserts enables a high number of teeth even on small tool diameters.
The large surface area in the insert seat of the Xtra·tec XT M5008 high-feed cutter along with the G67’s enhanced geometry enables stable and rigid indexable insert clamping and high process reliability. The tool is for use in aerospace, energy, general engineering, and automotive applications.
The use of Tiger·tec Gold and the thick insert’s four cutting edges reduces process costs. A high machining volume is achieved with the milling cutter thanks to the combination of low depths of cut and high feed per tooth rates. Because of extremely closely pitched tools, optimum productivity is ensured.
In an application example milling 304 stainless steel, a Walter ENMX08T316R-G67 WSP45G indexable insert with the G67 geometry increased tool life 25% compared to an insert with the existing geometry. The cutting data was the same for both inserts.
