Abstract
A chuck jaw that is configured and arranged to be used in combination with other chuck jaws for securely retaining a rotatable accessory, such as a drill bit, in position in a chuck assembly, where the chuck jaw includes a chuck jaw body that defines a generally longitudinal axis along the primary extension direction thereof and a chuck jaw tip that is positioned within the chuck jaw body and extends along at least a portion of the generally longitudinal axis of the chuck jaw body. The chuck jaw further includes an insulating material for preventing electrical current from passing between the rotatable accessory and the remainder of the chuck assembly via the chuck jaw.
