ABSTRACT:
A saw tool comprises a housing for incorporating a driving device therein, a base attached to the housing, a driving arm connected to the driving device to effect a reciprocating orbital motion, and a saw blade attached to the driving arm and extending through a slit in the base. The saw blade has a first saw tooth section formed on a top end thereof for biting a workpiece and a second saw tooth section formed on one side thereof. A rectangular through-hole can be accurately and rapidly formed in a workpiece such as a plaster board or veneer board, etc., with this saw tool. That is, a cutting method of the present invention comprises the steps of biting the workpiece with the first saw tooth section of the saw blade in the reciprocating orbital motion, while pressing a top end of the base and the top end of the saw blade against the workpiece, penetrating the saw blade through the workpiece, and subsequently, cutting the workpiece with the second saw tooth section by moving the saw blade along a cutting line on the workpiece. As a result, a cutting operation of one side of the rectangular through-hole is finished. By repeating the above cutting operation to each side of the rectangular through-hole, the rectangular through-hole is formed in the workpiece without drilling a starting through-hole in the workpiece.
