ABSTRACT:
A portable power tool such as a portable circular saw is provided with a sawdust collection system based on the generation of an air flow resulting from rotation of a rotary cutting blade, with this air flow being guided to transport sawdust resulting from cutting operations along a guide path through a first discharge aperture into a dust box in which the sawdust is precipitated, with a low-velocity air flow then passing out of the dust box through a second discharge aperture to be recirculated through the flow path. Extremely effective dust collection is attained with a simple configuration, while the dust box can be positioned such that the weight of accumulated sawdust therein does not significantly affect the balance or ease of operation of the portable power tool.
