One embodiment includes display device configured to wirelessly receive a first position status from a positioning device; display a first work-tool working-axis leveling status based on the first position status; receive cut parameters; receive a cut-start indication; determine a first work-tool position status difference based on cut parameters and a second position status; present a position status correction indicator; determine that a third position status is within cut parameters; send a cut-start signal to the positioning device operable to actuate the first work-tool; determine a work-tool cut completion; and send a cut-end signal to the positioning device operable to de-actuate the first work-tool.

A leveling device coupler assembly that includes a coupling head and a joint assembly coupled to the coupling head. The joint assembly can include a first and second rotatable coupling. The leveling device coupler assembly can also include a base coupler coupled to the joint assembly, with the base coupler and coupling head being coupled on opposing ends of the joint assembly. The leveling device coupler assembly can also include an electronic coupler assembly leveling device configured to at least detect a configuration status of the leveling device coupler assembly.

A drill extension for extending the working reach of a drill uses a hollow tubular body that has a shaft rotatably disposed therein and held therein by a pair of spaced apart bearings, each bearing attached to an inner surface of the body. The shaft has a male end that is received within a chuck of the drill and an opposing female receiver for receiving a shaft of a drill or the male end of another drill extension. A handle is attached the outer surface of the body member such that the handle has a ring member that is received within an encircling groove on the outer surface of the body member, the handle also has a grasp arm. At least one level is attached to the outer surface and is oriented either radially with respect to a longitudinal axis of the body member or in parallel with the axis or both.

A laser level including a housing. At least one laser generator supported by the housing and configured to emit at least one laser beam. A battery receiving portion configured to selectively receive a first battery pack and a second battery pack, the first and second battery packs providing power for the laser generator when received in the battery receiving portion. The first battery pack is configured to be coupleable to at least one of a drill, a saw and a sander. The second battery pack is configured to be blocked from coupling from the at least one of the drill, the saw and the sander to which the first battery pack is coupleable.

A method and apparatus for center height alignment of a boring bar is disclosed. The apparatus includes a seat member with a bottom and a back, and a digital angle gauge mounted to the seat member. The method includes the steps of: assembling an apparatus comprising a seat member and a digital angle gauge; calibrating the apparatus such that a Display of the digital angle gauge reads zero degrees; and aligning the center height of the boring bar by rotating the boring bar such that the Display of the digital angle gauge reads zero degrees when the apparatus is mounted onto the boring bar.

A device which includes a guide member which includes a first end portion and an opposing second end portion. The first end portion defines a first plane and an opening is defined by the guide member, wherein the opening extends along the guide member in a direction perpendicular to the first plane.
