2 7713VR Series Copy / Contour Milling Cutter ROUN INSERT MILLING CUTTER WITH INEXATION The 7713VR is our newest round insert cutter series. esigned with a new silver-satin surface treatment that reduces the body degradation during high performance plications and enhances the body tool life. This cutter series has an anti-rotation design which ensures a precise number of indexes per insert. This gives a maximum possible usage of the available edges for roughing plications. This unique patented pocket system prevents the inserts from rotating in the pocket, during heavy feed machining and unstable conditions. This 7713VR cutter is excellent for roughing and semi-finishing of all materials, specifically for Stainless and High Temperature Alloys as well as for, Tool and Aluminum Alloys.
