Abstract: THIS invention relates to a drilling accessory for a power drill drilling accessory that assists the operator of the power drill to correctly align and orientate the drill bit of the power drill with the target object, and collects the dust and/or debris arising from such drilling. The drilling accessory includes a cap having a plurality of differently sized guide holes and a container to which the cap is pivotally connected. The container comprises a first through hole, which on rotation of the cap relative to the container, enables the first through hole to be aligned with the require guide hole thereby to allow a drill bit to pass therethrough. The container further comprises a base having a planar support surface portion and a seal portion protruding outwardly from the support surface portion towards a contact lip, which contact lip defines a second through hole coaxially aligned with the first through hole.
