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.
Claims21
A tool bit for use with a power tool having a chuck and an anvil, the tool bit comprising:
- 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 configured to be inserted into the chuck of the power tool, the shank including
- a slot formed through the second end, the slot configured to receive a portion of the chuck to transfer rotational movement from the power tool to the tool bit, and
- a ball detent spaced circumferentially from the slot, the ball detent configured to receive a locking sphere of the chuck to lock the tool bit within the chuck,
- wherein 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.
10-16. (canceled)
A tool bit for use with a power tool having a chuck and an anvil, the tool bit comprising:
- 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 configured to be inserted into the chuck of the power tool, the shank including
- a first slot formed through the second end, the first slot configured to receive a first portion of the chuck to transfer rotational movement from the power tool to the tool bit,
- a second slot positioned diametrically opposite from the first slot and formed through the second end, the second slot configured to receive a second portion of the chuck to transfer rotational movement from the power tool to the tool bit,
- a first ball detent spaced circumferentially from the first and second slots, the first ball detent configured to receive a first locking sphere of the chuck to lock the tool bit within the chuck, and
- a second ball detent positioned diametrically opposite from the first ball detent, the second ball detent configured to receive a second locking sphere of the chuck to lock the tool bit within the chuck;
- wherein the shank is configured to limit insertion of the shank into the chuck such that the second end of the tool bit is not contacted by the anvil during operation of the power tool.
