PURPOSE: A sub-support for a hand drill is provided to maintain a body of the hand drill at a constant angular position and to attach/detach the sub-support to/from the body of the hand drill. CONSTITUTION: A sub-support(1) for a hand drill comprises a supporting section(2) having a roller(24) at one end thereof for allowing the sub-support(1) to move in front and rear directions. A rotating member(6) coupled to a rotating member(6) of a coupling section(8) is formed at both side ends of the roller(24). A fixing member(4) is formed at one end thereof with a fixing handle(42) and the other end thereof with a fixing nut(46) so as to couple the supporting section(2) to the coupling section(8) at a predetermined angle. The coupling section has a gear part(62) at one end thereof and a coupling hole(82) at the other end thereof, into which a drill body is inserted.
