Abstract

A jig or sabre saw has a horizontal foot to be placed on the work to be sawn. A drive unit is pivotally mounted on the foot and drives the tool in a tool holder. The two sides of the saw or other tool are supported by a guide device at points directly above the foot. The guide device is adapted to pivot with the drive unit so support the saw blade even when performing bevel cuts. The guide device and the drive unit may be arranged to pivot about two axes or about a single axis in relation to the foot.
