CS258028B1 - Portable drilling machine - Google Patents

Abstract

The solution relates to metal processing by cutting, in particular portable drilling machines for drilling holes in hard-to-reach places. The aim of the solution is to increase the strength of the head of the portable machine. According to the solution, the portable drilling machine is provided with a reinforcing sleeve in the upper part of the inserted element with grooves corresponding to and coinciding with the grooves of the gear hub, while threaded notches with a thread are made on the spindle on its outer surface, and the gear hub is made with an outer diameter that is smaller than the inner diameter of the thread of the spindle notch.
