Abstract
A hand tool providing for helical drive of tool bits is fabricated from a handle providing a coaxial bore with an abutment shoulder at one end, and a guide member having a helical rib along a bore extending therethrough is firmly seated in the open end of the bore. A drive spindle having a cooperating helical thread on its outer surface is slidably seated in the guide member and has its inner end engaged to limit its movement outwardly from the guide member. In the handle bore is provided a compression spring assembly which biases the spindle outwardly of the guide member. The tool is readily assembled by inserting the drive spindle into the guide member and locking it thereon and then driving the partially ribbed guide member into the bore of the handle after the compression spring assembly has been inserted therein.
