A rotary cutting tool, in particular a drill, is described, which comprises a shank and an exchangeable cutting tip (14). For this purpose, a locking geometry having an undercut of a first type and a torque transmission geometry is provided on the shank. A locking projection having a torque transmission counter-geometry is provided on the cutting tip, wherein, in a mounted state, the locking projection engages in the undercut of the first type and the torque transmission counter-geometry abuts the torque transmission geometry. The rotary cutting tool further comprises a securing unit, which holds the cutting tip on the shank.
