Abstract
A portable circular saw has a saw-blade compartment for accommodating a circular saw-blade, a motor compartment secured to the saw-blade compartment and projecting transversely therefrom away from the saw-blade, a rear handle extending rearwardly from the saw-blade compartment, and a forward handle connected to the saw-blade compartment and projecting transversely therefrom away from the saw-blade. The forward handle is hollow and defines a passageway therein which is in communication with the interior of the saw-blade compartment and is also adapted to be connected to a vacuum system, whereby this forward handle forms part of a sawdust removal system. Preferably, a strut forms part of and connects the forward handle to the motor compartment thereby defining a closed handle. The passageway in the forward handle is preferably connected to a fan in the motor compartment, but may be connected to an external source of vacuum. The housing of the saw may be constructed of three molded parts facilitating ease of assembly and providing a particular two handle arrangement designed to provide improved handling of the saw
