Drill Description

The Rotabest 130 B - when size matters, the XXL model among the Alfra core drilling machines is perfect for metal workers who need more: More power, more drill hole diameter, more cutting depth. For drill hole diameters up to 130 mm.

Our machine for big tasks can be combined with core drills up to a diameter of 130 mm, with step drills up to a diameter of 80 mm and with twist drills up to a diameter of 45 mm. It has an MK4 mount, soft start of the engine and a 4-speed gearbox. 33000 N magnetic holding force is ensuring a secure hold on ferromagnetic materials and the slip clutch is protecting the device from overload. The plus for special user-friendliness: among other things, soft-touch handles, a clearly arranged membrane keyboard and a cable in the comfortable length of 5 m.
