## Abstract

A removable chuck has a chuck member for holding a drill bit. Also, a mechanism is coupled with the chuck body to retain the chuck body to a drill spindle. The retention mechanism, in a first position, retains the chuck on the drill spindle and in a second position the chuck is enabled to be removed from the spindle.

## Claims

### Claim 1

A removable chuck comprising:
a sleeve for connecting with a rotating spindle;
a chuck coupled with said sleeve;
a locking mechanism for retaining said sleeve on the rotating spindle, said locking mechanism comprising a locking member, said locking member movable from a first position, coupling the sleeve with a spindle recess, to a second position, where said locking member is out of the spindle recess; and
said locking member moving between said first position, where said sleeve is locked with said spindle, to said second position, where said sleeve may be removed from the spindle.

### Claim 2 (depends on 1)

The removable chuck according to claim 1, wherein said locking member including an overall U-shaped spring for locking said sleeve in said spindle recess.

### Claim 3 (depends on 1)

The removable chuck according to claim 1, wherein said locking member including a housing, an activation member, and a biasing member, said activation member moving said biasing member between said first and second positions for locking and for enabling removal of said sleeve from the spindle.

### Claim 4 (depends on 3)

The removable chuck according to claim 3, wherein said activation member moves transverse to an axis of said spindle.

### Claim 5 (depends on 4)

The removable chuck according to claim 4, wherein said biasing member is an overall U-shaped spring.

### Claim 6

A hand tool comprising:
a hand tool having a rotatable spindle, said spindle including a recess; and
a removable chuck, said removable chuck comprising:
a sleeve for connecting with the rotatable spindle;
a chuck coupled with said sleeve;
a locking mechanism for retaining said sleeve on the rotatable spindle, said locking mechanism comprising a locking member, said locking member movable from a first position, coupling the sleeve with the spindle recess, to a second position, where said locking member is out of the spindle recess; and
said locking member moving between said first position, where said sleeve is locked with said spindle, to said second position, where said sleeve may be removed from the spindle.

### Claim 7 (depends on 6)

The removable chuck according to claim 6, wherein said locking member including an overall U-shaped spring for locking said sleeve in said spindle recess.

### Claim 8 (depends on 6)

The removable chuck according to claim 6, wherein said locking member including a housing, an activation member, and a biasing member, said activation member moving said biasing member between said first and second positions for locking and for enabling removal of said sleeve from the spindle.

### Claim 9 (depends on 8)

The removable chuck according to claim 8, wherein said activation member moves transverse to an axis of said spindle.

### Claim 10 (depends on 9)

The removable chuck according to claim 9, wherein said biasing member is an overall U-shaped spring.
