Abstract: A hand-held apparatus is for hole-making in an elongated body. The apparatus has a housing including a rotatable cutting tool arranged to be axially movable from a non-cutting position into a cutting position. The first end portion of the housing comprises a clamping device arranged to be adjusted from a first, inactive position into a second, active position, wherein the clamping device, in the active position, is arranged to hold the apparatus fixed to the elongated body. The apparatus further has a device for connecting to a driving means, for example a hand-held drill.

Abstract: A device is for an axial displacement of a hole saw for a hand-held drill, wherein the hole saw is coupled to the drill by a drive shaft, and the hole saw and an actuator are rotatably connected and positioned in a housing with a coupling for the drill. The actuator has an outer threaded portion which corresponds to an inner threaded portion in the housing so that the actuator and the hole saw are displaced axially along the drive shaft when the actuator rotates relative to the housing. The actuator is connected to the drive shaft via a slip clutch arranged to transfer and reduce a reduced torque from the drive shaft to the actuator.
