The Bosch GBM 32-4 rotary drill is a very powerful tool, featuring a 1500w motor and a 4-speed gearbox which allow it to drill diameters up to 32mm and perform heavy-duty operations in steel. It's not all about power though, as shown by the overload clutch and extra handle for better grip. The Bosch GBM 32-4 is ideal for core drilling in steel construction, in combination with Magnetic Drill Stand GMB 32 Professional.
