ABSTRACT:
The invention relates to a drill (4) and a device or a method for drilling boreholes in workpieces (3), in which a periodically acting radial force (19) is exerted on the drill head (5) of the drill (4). The drill head (5) of the drill (4) has a cutting edge (52) extending only over a part of the diameter D (51) and is designed to have a lateral, V-shaped chip removing groove or bead (59) and with a channel (12) with an outlet opening (56) in the drill head (5) for supplying a drill fluid (9). On a drill side (61) of the drill head (5) opposite the bead (59) between a first and a second cylinder casing partial surface (64, 65) of the drill head (5) a rear offset (63) is formed which reduces the cross section of the drill head (5) in relation to an enclosing cylinder casing surface (61) of the drill head (5).
