ABSTRACT:
Providing an oscillating tool for sanding a surface. The tool having a body defining an internal cavity which has a motor located therein. The motor has a motor shaft oriented in parallel alignment with the body. A crank is affixed to the motor which has a crank pin projecting therefrom. A lever arm is pivotably affixed to the body for rotation about a pivot axis generally perpendicular to the motor shaft. A lever arm cooperates with the crank pin to cause the lever arm to cyclically pivot back and forth in response to rotation of a motor shaft. A pad support is adapted to receive a work member. The planar pad support is affixed to the lever arm at a location spaced apart from the pivot axis and oscillates therewith. The pad support is provided with a substantially 90.degree. forward corner formed by a pair of facet edges. A pair of outwardly inclined straight side edges extend rearwardly from the facet edges on opposite sides of the pad center line. When the straight side edges are in use, the forward corner is inwardly offset, thereby minimizing wear in this region of the forward corner.
