ABSTRACT:
The invention relates to the provision of a power tool such as a jigsaw, circular saw or mitre saw which is provided with guideline generating means. The guidelines are typically generated as laser beams and the invention allows for the generation of at least first and second, side by side guidelines. The guidelines are generated onto the workpiece and the area which lies between the guidelines defines the path along which a cutting blade of the power tool is to be directed. Preferably the guidelines are spaced such that a first guideline lies to one side of the blade and the other guideline lies to the other side of the blade thus allowing the guidelines to be viewable on both sides during the cutting operation.
