[ COVER STORY ] Complete solution for CORE DRILLING FROM BOSCH The new diamond drilling system from Bosch is a powerful complete solution for core drilling. This allows HVAC installers and diamond drilling specialists to achieve a fast drilling rate, even at large diameters, in masonry and concrete. “T he system comprises the GDB 180 WE Professional, the GDB 350 WE Professional diamond drill, the GCR 180 Professional, and the GCR 350 Professional drill stands,” explains Campbell Mhodi, Bosch Professional Power Tools senior brand manager. “The system provides high performance with a long lifetime and high flexibility, due to comprehensive system accessories. Furthermore, Bosch is also simultaneously launching new diamond core cutters for dry and wet drilling, thus offering a coordinated, complete system,” Mhodi reveals. The GDB 180 WE Professional is exceptionally lightweight at only 5.2kg, 6 | HIRE SA | MAY 2017 with a powerful 2 000W motor and two- speed gearbox. At 180mm, it also offers the largest drilling diameter in this performance category. A major advantage is that it can be used as a hand-held tool, and also together with the GCR 180 Professional drill stand. When doing so, it can be used close to the wall thanks to its small corner measurement. The GDB 180 WE Professional is also exceptionally robust because its gearbox is lubricated with an oil bath rather than with grease. This optimum gearbox lubrication ensures a high degree of efficiency and a long lifetime. The die-cast aluminium housing and a flexible, highly break resistant cord also contribute to the tool’s extended lifetime. The GDB 180 WE Professional covers a range of applications. It is suitable for dry and wet drilling. Typical applications are core drilling for electrical installation sockets and reinforcements, cable and tray feedthroughs, and breakthroughs for HVAC installations. Two bubble vials integrated into the housing make it easier to align the tool precisely for each drilling application. The 3 200W GDB 350 WE Professional is designed for large drilling diameters of up to 350mm. As with the smaller model, a long lifetime is ensured by oil bath lubrication of the gearbox, a die-cast aluminium housing, and a flexible, break resistant cord. To ensure that the gearbox is completely supplied with oil even during vertical drilling, it also has an integrated oil pump.
