Abstract
A radial tapping attachment for a motor-driven tool includes an enclosed, box-shaped housing, a main shaft assembly adapted to retain a tap, a drive mechanism rotatably driven by the tool and a guide member assembly for supporting an object to be tapped. The main shaft assembly includes a main shaft rotatably coupled to the housing by a pair of bearings, a pair of spaced apart discs fixedly mounted on the main shaft, and a pair of axially mounted compression springs that allow for slight, bi-directional, axial displacement of the main shaft relative to the housing. The drive mechanism includes a drive shaft rotatably coupled to the housing at an approximate right angle relative to the main shaft and a drive wheel mounted on the drive shaft that selectively engages the pair of discs to rotate the main shaft in either direction when an axial force is applied to the tap.
