Abstract
The preferred embodiment of a rotary hand tool attachment is intended for coupling to a rotary power hand tool of the type that has a housing with a substantially cylindrical nose portion and a motor having an output shaft with a mounting coupling for receiving a drive shaft extending forwardly therefrom. The attachment includes a housing having an output shaft configured to drive a rotating tool, and an input shaft configured to couple with the drive shaft so that the motor output shaft, drive shaft and input shaft are aligned on a common axis. The housing also includes a mounting collar with a substantially cylindrical inside surface that is sized to slidably and snugly engage the nose portion. Additionally, a thin annular cylindrical layer of resilient material is disposed between the cylindrical inside surface of the housing and the nose portion.
