Chuck

A chuck for use with a manual or powered driver having a rotatable drive shaft, said chuck comprising:

• a. a generally cylindrical body member having (i) a nose section having an axial bore formed therein, and (ii) a tail section configured to rotate with the drive shaft of the driver;
• b. a plurality of jaws slidably disposed within said body in communication with said nose section axial bore;
• c. a nut disposed rotatably about but axially fixed to said body and in driving engagement with said jaws so that rotation of said nut with respect to said body drives said jaws into and out of said nose section axial bore;
• d. a bearing including an inner race, an outer race and bearing balls maintained therebetween, said bearing being disposed between said body and said nut;
• and
• e. a rust resistant nosepiece secured to said body nose section, said nosepiece having a generally cylindrical sidewall and an end wall extending radially inward therefrom.
