ABSTRACT:
A chuck device for a power tool includes a follower rotatably and slidably received in a tube and coupled to and driven by a power tool and having a hole for receiving a driving stem. One or more balls are slidably received in the follower and may be forced inward of the follower to engage with the driving stem for allowing the driving stem to be driven by the follower. The balls may be disengaged from the driving stem when the ball is received in the annular recess of the tube for preventing the driving stem from being over-driven by the power tool.
