An apparatus includes a rotatable device, which may be a keyless chuck, a keyless chuck adapter, a collet chuck, a collet adapter, a set screw bit retaining chuck, or a set screw bit retaining adapter. The rotatable device is configured to be mounted to a power tool for rotational driving of the rotatable device. The rotatable device is configured to receive a first bit device detachably mounted in the rotatable device for powering rotational movement of the first bit device. A mounting section having at least one flat secant side is defined on the rotatable device, which is capable of being rotatably driven by the power tool. The mounting section includes at least one locking mechanism on it. The generally cylindrical mounting section is adapted for insertion in and engagement with a bit holding attachment.
