Abstract: Various embodiments of a drill are described in which the drill includes an air motor assembly having an output spindle and a head attachment having a cutter spindle. The head attachment can be removably connected to the motor assembly, and capable of being configured in at least (i) a first mode in which the cutter spindle is parallel to the output spindle of the air motor assembly, and (ii) a second mode in which the cutter spindle is orthogonal to the output spindle of the air motor assembly.

Abstract: A clutching arrangement of a positive feed drill comprises a first shaft and a second shaft. The first shaft has a first longitudinal axis and the second shaft has a second longitudinal axis. The first longitudinal axis and the second longitudinal axis being generally aligned. A first clutch gear assembly being rotatable about the first axis. A second clutch gear assembly being rotatable about the second axis. The second clutch gear assembly and the second shaft being axially moveable toward and away from the first clutch gear assembly and the first shaft.

Abstract: A nut-plate riveter which includes multiple pistons which assist in creating a pulling force. The nut-plate riveter provides that spent mandrels are pulled through the tool, thereby avoiding problems in the field. The nut-plate riveter includes a handle and a plurality of pistons disposed in the handle. Cavities are proximate the pistons for pressurizing the pistons, and air supply passages are in communication with the cavities for supplying air to the cavities to pressurize the pistons. A piston rod is engaged with at least one of the pistons, and the piston rod has a longitudinal bore therethrough which is configured to receive a spent mandrel. A deflector fitting may be disposed at an end of the nut-plate riveter.
