1. A power tool system comprising:
- a common body portion including a housing defining a handle and a motor mounted within the housing, the motor having a front end and a rear end and arranged to drive a rotatable drive spindle extending from the front end, the housing further defining an opening around the rotatable output, the motor mounted within the housing by a plurality of supports spaced along the axial length of the motor, a first of the plurality of supports being adjacent one of the front end and the rear end and radially spaced from the motor and a second of the plurality of supports being adjacent the other of the front end and rear end and in direct contact with the motor to preclude radial movement of the motor relative to the second support;
a plurality of attachment members each selectively and releasably attachable to the common body portion, each of the plurality of attachment members including a working portion driven by a driven spindle, the driven spindle for engaging the rotatable drive spindle;
whereby a small degree of radial movement between the motor relative to the first of the supports is permitted prior to releasable attachment of one of the attachment members to the common body portion and said small degree of radial movement is precluded upon releasable attachment of one of the attachment members to the common body portion.

Abstract
A power tool (2) includes a motor (22) pivotally mounted within the housing of the tool. The tool is able to accept any one of a plurality of attachment members (32). The motor (22) is adapted to pivot in order that accurate axial alignment with any one of the attachment members presented to the motor occurs.

9. A power tool comprising:
-
a tool housing;
a motor having a generally cylindrical body and a rotatable output spindle, the generally cylindrical body having a front end and a rear end, the rotatable output extending from the front end;
a tool head releasably attachable to the tool housing, the tool head including a driven spindle for engagement with the rotatable output spindle; and
a plurality of ribs spaced axially along a length of the motor for supporting the motor, a first rib of the plurality of ribs disposed adjacent a front end of the body and defining at least a portion of a circular opening with a rigid diameter slightly larger than a diameter of the generally cylindrical body such that the rigid diameter is radially spaced from and allows a small degree of radial movement of the motor relative to the first rib in any direction substantially perpendicular to the length of the motor prior to releasable attachment of the tool head to the tool housing and a second rib of the plurality of ribs in direct contact with the motor to preclude radial movement of the motor relative to the second rib, said small degree of radial movement of the motor relative to the first rib being precluded upon releasable attachment of the tool head to the tool housing. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21)

22. A power tool comprising:
-
a tool housing;
a tool head removably attached to the tool housing; and
a motor including a generally cylindrical body having a first end and a second end, the motor further including a rotatable output spindle extending from the second end, the motor disposed within the tool housing, the first end radially supported directly by the tool housing and the second end radially supported directly by the tool head such that the first end is radially fixed within the tool housing, rotatable output spindle is radially movable prior to releasable attachment of the tool head to the tool housing, and the tool head precludes radial movement of the rotatable output spindle upon releasable attachment of the tool head to the tool body. - View Dependent Claims (23, 24, 25, 26, 27)
