ABSTRACT:
A housing apparatus for an electric power tool which has a nose cone, a clam shell housing, and a bearing plate. The nose cone contains a bevel portion, a bearing plate retaining portion, and at least one hole oriented generally transverse to a tool axis for reception of at least one fastener. The clam shell housing has a first and a second housing segment, each having a matching bevel portion for cooperation with the bevel portion of the nose cone. The first and the second housing segments each further have a bearing plate retaining portion and at least hole aligned with the at least hole of the nose cone for simultaneous reception of the at least one fastener. The bearing plate has at least one threaded hole oriented generally transverse to the tool axis for receiving the at least one fastener. The bearing plate is located between the retaining portion of the nose cone and the retaining portion of the clam shell housing. The matching bevel portion cooperates with the bevel portion to convert a generally transverse force resulting from the engaging reception of the at least one fastener to an axial force which acts to axially retain the bearing plate between the retaining portion of the nose cone and the retaining portion of the clam shell housing, and acts to secure the nose cone to the clam shell housing.
