ABSTRACT:
A portable drilling machine includes a housing; a drill chuck positioned on a front surface of the housing; a drill bit detachably coupled to the drill chuck; a driver positioned inside the housing to provide either the drill bit or the drill chuck with a rotational driving force; an anti-dust cover having a rear anti-dust cover formed in a cup shape with a drill through-hole formed in a central region of a bottom surface of the rear anti-dust cover and a front anti-dust cover formed in a tube shape to be coupled to the rear anti-dust cover, the front anti-dust cover being adapted to move towards the bottom surface of the rear anti-dust cover when acted on by pressure towards the housing and return to original position when the pressure is removed; and a retainer for detachably coupling the rear anti-dust cover to an outer surface of either the housing or the drill chuck. The rotational motion of the drill bit is not interfered with by the anti-dust cover, and the dust collection space is increased.
