Abstract
A drilling tool consisting of a drill shank having a drill point and of a transition section which adjoins the drill shank in the axial direction and which merges into a clamping shank, the transition section being heat-treated in such a way that it has higher bending elasticity compared with the clamping shank and/or the drill shank.
Claims13
A method of producing a drilling tool of the type formed as a single integral piece comprising a transition section integrally formed between a drill shank and a clamping shank with the transition section being subjected to a heat treatment in such a way that it is given higher bending and torsional elasticity compared with the clamping shank and the drill shank within a region subjected to the heat treatment.
A drilling tool of the type having a drill shank with a drill point and a transition section which adjoins the drill shank in the axial direction and which merges into a clamping shank, the drilling tool comprising the drill shank, transition section and clamping shank forming a single integral piece, the transition section being heat-treated such that it has higher bending and torsional elasticity compared with at least one of the clamping shank and the drill shank, the drill shank forming a front twist-drill section and an adjoining tap section, the transition section adjoining the tap section with the clamping shank, a countersinking section being arranged between the transition section and the clamping shank.
