Abstract
A device for use in drilling is adapted to be used in cooperation with a drilling unit that comprises a bush inside which a drill bit can advance and retract relative to the bush, the bush being provided with an opening from which the drill bit can protrude towards a workpiece or an arrangement of workpieces. The device includes a first portion and a second portion. The first portion is formed so as to fit into the opening of the bush. The second portion is formed so as to fit into a pre-drilled pilot hole in the workpiece or in at least one workpiece of the arrangement.

A device for drilling, wherein the device is adapted to be used in cooperation with a drilling unit that comprises a bush inside which a drill bit can advance and retract relative to the bush, the bush being provided with an opening from which the drill bit can protrude towards a workpiece or an arrangement of workpieces,
- the device comprising a first portion which is formed so as to fit into the opening of the bush, and
- the device comprising a second portion which is formed so as to fit into a pre-drilled pilot hole in the workpiece or in at least one workpiece of the arrangement.
A method for drilling using a drilling unit, wherein the drilling unit comprises a bush inside which a drill bit can advance and retract relative to the bush, the bush being provided with an opening from which the drill bit can protrude towards a workpiece or an arrangement of workpieces, wherein the method comprises drilling by the drill bit including drilling through a device, wherein the device comprises a first portion formed so as to fit into the opening of the bush and wherein the device comprises a second portion formed so as to fit into a pre-drilled pilot hole in the workpiece or in at least one workpiece of the arrangement, the first portion being arranged within the opening and the second portion being arranged within the pre-drilled pilot hole.
A method for preparing a workpiece or an arrangement of workpieces for drilling, comprising inserting a second portion of a device being adapted to be used in cooperation with a drilling unit that comprises a bush inside which a drill bit can advance and retract relative to the bush, the bush being provided with an opening from which the drill bit can protrude towards a workpiece or an arrangement of workpieces, the device comprising a first portion which is formed to fit into the opening of the bush, and the device comprising a second portion which is formed so as to fit into a pre-drilled pilot hole in the workpiece or in at least one workpiece of the arrangement, into a pre-drilled pilot hole in the workpiece or in at least one workpiece of the arrangement, thereby providing a workpiece or an arrangement of workpieces that is pre-equipped with the device for a drilling operation to be performed.
