Intended for machining ISO K (cast iron) materials, Tiger•tec® Silver® RK5 and RK7 geometries have CVD coating and plateau step. Latter enables location face to be ground after coating. Evenly ground faces ensure seating with optimal stability, which minimizes cutting edge wear and promotes tool life and process reliability. While RK5 flat top insert suits cast iron roughing operations, RK7 insert suits heavy, interrupted cuts; large depth-of-cut variations; and hard cast skin.
