Abstract
1306248 Milling cutter WELDON TOOL CO 20 Nov 1970 [9 April 1970] 55238/70 Addition to 1285076 Heading B3K A milling cutter has four helical cutting edges 140, each of which has alternate peaks and valleys 147, 149, the peaks being flat, and the depth from the peaks to the valleys being small compared to the pitch P of the flat portions. The flat portions are arranged helically so as to overlap, and the axial distance of each flat portion multiplied by the number of cutting edges is at least as great as the pitch P.
