Alfra Drilling Machines RB 50 X, 230V

The magnetic core drilling machine can be fixed with a switchable electromagnet on ferromagnetic workpieces. The electromagnet and the motor can be switched on and off with the large buttons of the control panel. The LED above the front panel shows the operating status of the machine and the adhesive force of the magnet. A self-adjusting dovetail guide on which the motor is mounted can be adjusted in height with the star handle or be locked with a slide. On the back of the machine is the nameplate and an attachment for the enclosed Allen keys.
