Cutting tool for turning and drilling from solid

摘要

The invention relates to a cutting tool for rotating and drilling into solid blocks, comprising a drill shank ( 1 ) and a cutting head ( 2 ) on one end. The cutting head ( 2 ) has a straight, front-face cutting edge ( 4 ) extending approximately crosswise in relation to the drill axis ( 3 ). The cutting head ( 2 ) also comprises a section ( 8 ) protruding from the shank of the drill ( 1 ) at a height (h) ranging from at least 5% to a maximum of 40% of the diameter (d) of the drill and at a width (b) ranging from at least 5% to a maximum of 40% of the diameter (d) of the drill. The section ( 8 ) comprises a straight, lateral cutting edge ( 5 ) which merges into a straight, rear-sided cutting edge ( 7 ) extending in an approximately parallel manner in relation to the front-faced cutting edge ( 4 ).
