Abstract
An oscillating tool for sanding a surface has a body (12) defining an internal cavity (14) and a motor (20) located therein The motor has a motor shaft (22) oriented in parallel with the body. A crank (24) is affixed to the motor which has a crank pin (26) projecting therefrom. A lever arm (34) is pivotably affixed to the body for rotation about a pivot axis generally perpendicular to the motor shaft. The lever arm cooperates with the crank pin to cause the lever arm to cyclically pivot back and forth. A pad support (18) is adapted to receive a work member (19). The planar pad support is affixed to the lever arm at a location spaced apart from the pivot axis and oscillated therewith. The pad support has a substantially 90 degree forward corner (110) formed by a pair or facet edges and a pair of outwardly inclined straight side edges (116, 118).
