A collet chuck assembly used for the attachment of a tap to the spindle of a tapping machine is provided. A bore for insertion of the base end of the tap is formed in the lower portion of a cylindrical portion, and at least one O-ring is mounted on the inner wall of the bore such that it is open to view on the inner peripheral face thereof. With the O-ring, the tap is held in place so as to prevent it from slipping down, and is supported somewhat floatingly within the bore in the diametrical direction. The cylindrical portion is provided therein with a pair of locking faces for locking the prismatic portion of the tap in place so as to inhibit any turning thereof and with a pair of steps or a set screw for controlling the amount of insertion of the tap thereinto.
