Abstract: A tool bit for use with a power tool having a chuck and an anvil includes a first end, a second end opposite the first end, a body defining the first end of the tool bit, and a shank coupled to the body and defining the second end of the tool bit. The shank includes a slot formed through the second end. The slot is configured to receive a portion of the chuck to transfer rotational movement from the power tool to the tool bit. The shank also includes a ball detent spaced circumferentially from the slot. The ball detent is configured to receive a locking sphere of the chuck to lock the tool bit with the chuck. The slot is sized to limit insertion of the shank into the chuck, thereby providing a space between the second end of the tool bit and the anvil.

Abstract: A flexible shaft includes a tubular body extending along a central longitudinal axis and having proximal and distal ends opposite one another. The flexible shaft also includes a slot defined by the tubular body and extending along a helical path around and along at least a portion of the body between the proximal and distal ends. The helical path extends around the portion of the body for a plurality of rotations. The slot defines at least two teeth adjacent one another along a direction parallel to the central axis. Each tooth of the two teeth has a feature. In some implementations, a line extending through center points of the features on the two teeth is angularly offset from the central longitudinal axis. In some implementations, a line parallel to the central longitudinal axis intersects a different point on each feature of the two teeth.
