PURPOSE: A hand tool for removing burr is provided to reduce working hours by eliminating burr conveniently and easily in processing holes, and to increase the productivity by improving working efficiency. CONSTITUTION: A hand tool(10) for eliminating burr is composed of a hollow hand tool body(20) having elongated guide holes(21) at both sides; a palm support member(30) installed in the upper part of the hand tool body to hold in removing burr; a screw shaft(40) inserted to the hand tool body, and turned in removing burr to form two spiral grooves; a grip handle(50) pulling along the guide hole with a support shaft(51) inserted to the spiral groove; and a cutter(70) installed in the lower part of the screw shaft to eliminate burr with turning by receiving rotational force of the screw shaft. Working hours are reduced, and working efficiency is improved with removing burr conveniently and promptly.
