An apparatus for the formation of a channel in a workpiece located at a first face of a base of the body of the apparatus, the channel formed by a drill assembly of the apparatus connected to drive means located on a second opposing side of the base, the drill assembly and drive means mounted so as to be movable in a guided manner with respect to the base. The movement is achieved by manual movement of a gripping means of an actuation means of the apparatus with respect to the base, so as to cause one or more flexible connecting members of the actuation means which are positioned intermediate the gripping means and drill assembly to move and advance the drill assembly towards the workpiece. The channel is formed in accurate manner which then allows the same to receive securing means typically to allow a joint between first and second workpieces to be accurately formed.
