Alfra Drilling Machines RB 35/50X

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. A self-adjusting dovetail guide on which the motor is mounted can be adjusted in height with the star handle. On the back of the machine are the nameplate and an attachment for the enclosed Allen keys.
