Problems to construct the second order tool for creating helical clearance grooves on spiral drills are considered. Profiling of clearance grooves is performed on the basis of method to specify a profile of the groove by two rectilinear generatrices. Analytical and geometrical descriptions of the groove profile and the profile of the shaper disc-cuter tooth are given. Relations to calculate the initial parameters for plotting the groove profile are presented. A method to optimize parameters of the cutter tooth profile is offered.
