FIELD: mechanical engineering. SUBSTANCE: hole drilling device has bushing spring-loaded on body. Bushing embraces tool spindle of drilling device. Body also carries bracket capable of turning over cylindrical surface made eccentric to drill axis. Readjustable members locking drill in position are installed on bracket. The construction enables drilling of holes over both straight line and circumference without preliminary marking, irrespective of position of this circumference and value of its radius which reduces preparatory time. EFFECT: enhanced efficiency of drilling. 2 dwg
