Portable power tool equipped with dust collector

A portable power tool comprising:

• motor drive means and transmission means coupled thereto;
• housing means for enclosing and supporting said motor drive means and transmission means;
• a base positioned below said housing means and attached thereto;
• a rotary cutting member coupled to said transmission means to be rotated thereby, a part of said rotary cutting member being positioned above said base and said motor drive means being positioned on one side of said rotary cutting member with respect to a plane of rotation of said rotary cutting member;
• cover means attached to said housing means for substantially entirely enclosing said part of said rotary cutting member positioned above said base, said cover means having a sawdust discharge aperture and a residual sawdust recycling aperture formed therein, said cover means moreover being internally shaped in a manner defining a sawdust transfer passage for directing a current of air resulting from rotation of said rotary cutting member into said sawdust discharge aperture;
• and
• a dust box mounted above said base, positioned entirely on the same side of said rotary cutting member with respect to said plane of rotation as said motor drive means and moreover positioned within a space formed between a front portion of said housing means, a lateral face of a front portion of said cover means, and an upper face of a front portion of said base, said dust box having at least one internal chamber for accumulation of dust particles produced by operation of said rotary cutting member, and further having an inlet aperture formed therein positioned to communicate with said sawdust discharge aperture of said cover means and an outlet aperture positioned to communicate with said residual dust recycling aperture of said cover means.
