Abstract
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.
Claims23
Apparatus comprising:
- a keyless chuck adapter,
- the keyless chuck adapter having a longitudinal shaft sized and shaped to be grasped by a mounting chuck of a power tool for rotational driving thereof, the keyless chuck adapter being separate from the mounting chuck;
- the keyless chuck adapter having a plurality of jaws configured to receive a first bit device detachably mounted therebetween for powering rotational movement thereof, the keyless chuck adapter having a sleeve at an outer circumference of the keyless chuck adapter for opening and closing of the jaws for securely gripping bit devices of different sizes and shapes without using a key or tool;
- the keyless chuck adapter including a mounting section defined thereon, having at least one flat secant side, the mounting section capable of being rotatably driven by the power tool, said mounting section including at least one retaining means thereon or therein, said mounting section being adapted for insertion into and engagement with a bit holding attachment;
- and
- a bit holding attachment having:
- a mounting cavity sized and shaped to receive a portion of the keyless chuck adapter having the mounting section, the mounting cavity having at least one flat secant side sized and shaped to receive the flat secant side of the mounting section, the bit holding attachment having means for engaging the retaining means of the mounting section;
- and
- a forward bit securement means at an end of the bit holding attachment opposite a mounting end thereof, for detachably receiving and retaining a second bit device therein.
Apparatus comprising:
- a keyless chuck adapter,
- the keyless chuck adapter having a longitudinal shaft sized and shaped to be grasped by a mounting chuck of a power tool for rotational driving thereof, the keyless chuck adapter being separate from the mounting chuck;
- the keyless chuck adapter having a plurality of jaws configured to receive a first bit device detachably mounted therebetween for powering rotational movement thereof, the keyless chuck adapter having a sleeve at an outer perimeter of the keyless chuck adapter for opening and closing of the jaws for securely gripping bit devices of different sizes and shapes without using a key or tool;
- the keyless chuck adapter including a mounting section defined thereon, the mounting section capable of being rotatably driven by the power tool, said mounting section being adapted for slidable insertion into and engagement with a bit holding attachment;
- and
- a bit holding attachment having:
- a mounting cavity sized and shaped to slidably receive the mounting section of the keyless chuck adapter while preventing relative rotation between the mounting section and the bit holding attachment;
- and
- a forward bit securement means at an end of the bit holding attachment opposite a mounting end thereof, for detachably receiving and retaining a second bit device therein.
