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.

Abstract: A support for endless grinding sleeves for grinding workpieces has a casing which axially running slots or grooves and the support has a round outline in cross section. An axial hole through the support becomes narrower along its length and is designed to receive a wedging cone that is to be drivingly joined with a shaft. The outer surface of the support is made somewhat smaller in size than the inner circumference of the endless grinding sleeve that is to be placed on the support and the cone is driven into the support to radially expand it into engagement with the sleeve.
