Abstract

A drill for chipforming machining comprising a drill body (11), two cutting inserts (12, 13) and screws (14, 15). The cutting inserts are screwed to cutting insert sites (18, 19) in the axially forward end of the drill (10). The screws force the cutting inserts radially outwardly during tightening until a shoulder (28) at the lower side of each cutting insert abuts against a vertical support surface (22) on the drill body (11). The cutting inserts are tangentially mounted, i.e. they have holes for accomodating the screws, which terminates in the chip surfaces of the cutting inserts.
