Abstract

A router comprises a cage supporting a drive unit having a shaft on which a cutter can be fixed. A rest plate is provided with an aperture for moving the cutter therethrough. The rest plate is connected to the cage through two guide columns on which it is displaceable in axial directions of the cutter and arrestable in a selected position. The rest plate is a hollow structure open downwardly where it is closed by a detachable cover having a smooth outer surface. A cavity of the plate communicates with and encircles the aperture 21 for the cutter and grows toward an exhaust connection which extends tangentially to the cutter, i.e. in the direction in which the millings are thrown. The exhaust connection can be connected to an exhauster. Laterally on the rest plate, an adjustable slide stop may be provided having an angled leg which can be brought into a position flush with the bottom surface of the rest plate or moved downward therefrom. A chip screen is mounted for adjustable movement toward and away from the rest plate.
