DRILL, AND DRILLING METHOD |
摘要 |
The invention relates to a drill (4) as well as to a device and a method for drilling bores into workpieces (3), a periodically effective radial force (19) being applied to the boring head (5) of the drill (4). The boring head (5) of the drill (4) comprises a blade (52) that extends only across part of the diameter D (51) while being embodied with a lateral, V-shaped chip-removing groove or bead (59) and a channel (12) encompassing an outlet (56) in the boring head (5) for delivering a drilling fluid (9). A recess (63) that reduces the cross section of the boring head (5) in relation to an enveloping cylindrical outer surface (62) of the boring head (5) is configured between a first and a second cylindrical outer surface (64, 75) of the boring head (5) on a side (61) of the boring head (5) which faces away from the bead (59). |
