Alfra Drilling Machines RB 80 SP, 230V

The magnetic core drilling machine can be attached to ferromagnetic work pieces using the installed mechanically switchable permanent magnet. For this purpose, the magnetic lever must be pressed downwards and the safety tab must latch into place correctly. The motor can be switched on and off using the large switch on the side. A self- adjusting linear guide which the motor is attached to can be vertically adjusted using the rotary handle. The model plate and an attachment possibility for the allen wrench included can be found on the back of the machine.
