Abstract
A removable nosepiece for a chuck includes a plastic and/or metal ring which is removably mounted on a distal portion of either the main body or a sleeve of the chuck so that the ring is concentric with the central longitudinal axis of the chuck. The removable nosepiece may include a washer-shaped member of rubber extending radially inwardly from the plastic and/or metal ring. If provided, the rubber washer resiliently engages and centers a tool inserted into the chuck through the central aperture of the washer.

A plastic nosepiece for a chuck comprising:
- a toroidal member of plastic removably mounted on a distal portion of said chuck so that when said member is mounted on said chuck, said member is substantially concentric with a tool inserted in said chuck and a distal surface of said member becomes the distal-most surface of said chuck.
A nosepiece for a chuck comprising:
- a first toroidal member of plastic removably mounted on a distal portion of said chuck so that when said first member is mounted on said chuck, said first member is substantially concentric with a tool inserted in said chuck;
- and
- a second toroidal member of metal concentrically mounted on a distal surface of said first member so that when said first member is mounted on said chuck, a distal surface of said second member becomes the distal-most surface of said chuck.
