Abstract
Abstract A handle for a hand-held device such as a hammer drill, includes an axially elongated tubular support member formed of a wear-resistant material and a grip member laterally encircling at least a portion of the outer surface of the support member. The grip member is fitted into a recess in the outer surface of the support member. Radially outwardly extending flange-like projections on the support member form the opposite ends of the recesses and project radially outwardly from the outer surface of the grip member for protecting it against wear.
