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.
Claims17
A system for controllable, linear movement of a cutting tool from a non-cutting position to a cutting position in a hole-making apparatus, the system comprising:
- an adapter configured such that the cutting tool can be releasably attached thereto, wherein the adapter is rotatably attached to an actuator such that turning of the actuator causes axial movement of the adapter thereby moving the cutting tool from the non-cutting position to the cutting position, and wherein the adapter comprises a cut-out configured for releasable connection of a driveshaft for providing rotation to the adapter;
- and
- the driveshaft, wherein the driveshaft comprises a first end portion releasably connected to the adapter via the cut-out in the adapter, and a second end portion configured for releasable attachment to a driving means;
- wherein the actuator is configured to allow passage of the driveshaft therethrough.
A system for controllable, linear movement of a cutting tool from a non-cutting position to a cutting position in a hole-making apparatus, the system comprising an adapter configured such that the cutting tool can be releasably attached thereto, wherein the adapter is rotatably attached to an actuator such that turning of the actuator causes axial movement of the adapter thereby moving the cutting tool from the non-cutting position to the cutting position, and wherein the actuator is a screw provided with an external threaded portion.
