ABSTRACT:
A power rotary tool has a drive spindle and a chuck device mounted on the end of the spindle. The chuck device has a body member with an axial bore through an end thereof that defines a female pilot section and a threaded longitudinal section adjacent and rearward of the female pilot section. A flat shoulder is defined on the body member rearward of the threaded longitudinal section. The drive spindle has a male pilot section at a forward end thereof and a threaded longitudinal section adjacent and rearward of the male pilot section. A radial stop is defined on the drive spindle adjacent and rearward of the threaded section. Upon mounting of the chuck onto the drive spindle, the male pilot longitudinal section slides tightly within and uniformly contacts the female pilot longitudinal section and the shoulder of the body member abuts directly against the radially extending stop defined on the drive spindle.
