Alfra Drilling Machines RB 35 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 keys on the operator panel.

The machine is equipped with two LEDs: The magnet sensor LED on the housing indicates the operating state of the motor and the magnet’s holding force. The motor LED on the operating panel is used to control the temperature of the motor and the state of the carbon brushes.

A self-adjusting dovetail guide which the motor is attached to can be vertically adjusted using the star handle.

The type plate and an attachment possibility for the Allen keys included can be found on the back of the machine.
