ABSTRACT:
A plunge-type router comprising a motor housing having a driving motor provided therein, a base having a workpiece-engaging flange member and a support plate axially movable with respect to the flange member along substantially perpendicular guide means, the support plate being biassed away from the flange member and provided with a bore to receive the motor housing and clamping means to secure the housing in the bore, and locking means effective to prevent undesired separation of the motor housing from the support plate.
The potential hazard presented to the operator by accidental separation of the motor housing from the base is thereby avoided.
