BOSCH CORE DRILL GSB 90-2 E / 110V. GSB 90-2 E Professional Hammer Drill. Impact drill GSB90-2E 2-speed from Bosch. The powerful one for every use. High-performance, high-torque motor. Design perfectly suited to drilling without percussion with diamond drill bits (concrete, masonry works with reinforcing bars), to large drilling diameters (wood, metal, plastic) as well as short diamond crowns, hole saws and carbide drills. Solid metal housing for long life. Anti-Rotation safety clutch for safer work: if the drill bit jams, the motor shuts off automatically. 2-speed mechanical gear mechanism allowing you to change speed at idle and when stopping. Additional 360° rotatable handle to cope with all conditions of use. Spindle collar Ø 43 mm (European standard), adaptable to all drilling supports. Unfortunatley with the the chuck on it doesn`t fit in so I cut a slot in the box. It worked for me. It will come in that box. Amazing drill, by far the best core drill I have ever used. All the original bits included.
