press release

The new diamond drilling system from Bosch is a powerful complete solution for core drilling. This now enables HVAC installers and diamond drilling specialists to achieve a fast drilling rate even at large diameters in masonry and concrete. The system comprises the GDB 180 WE Professional and GDB 350 WE Professional diamond drills and the GCR 180 Professional and GCR 350 Professional drill stands. It excels by providing 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.

GDB 180 WE Professional for drilling diameters of up to 180 millimeters
The GDB 180 WE Professional with its weight of 5.2 kilograms and its 2000 watt motor with two-speed gearbox is exceptionally lightweight and powerful. At 180 millimeters it also offers the largest drilling diameter in this performance category. 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. The optimum gearbox lubrication ensures a high degree of efficiency and a long lifetime. The die-cast aluminum housing and a flexible, very break-resistant cord also contribute to the tool’s long lifetime.

The GDB 180 WE Professional covers a wide 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.

GDB 350 WE Professional for drilling diameters of up to 350 millimeters
The GDB 350 WE Professional is designed for large drilling diameters of up to 350 millimeters. It offers 3200 watts and is therefore exceptionally powerful. As with the smaller model, a long lifetime is ensured by oil bath lubrication of the gearbox, a die-cast aluminum housing and a flexible, very break-resistant cord. To ensure that the gearbox is completely supplied with oil even during vertical drilling, the GDB 350 WE Professional also has an integrated oil pump.

The diamond drill is complemented by the GCR 350 Professional drill stand. The work angle can be set using the scale on the GCR 350 Professional, enabling the tool to be aligned precisely during drilling. The speed and torque can be flexibly adapted to the drilling application thanks to a three-speed gearbox. The GDB 350 WE Professional is designed for wet drilling in reinforced and non-reinforced concrete and masonry, where it performs tasks such as breakthroughs for supply and disposal lines, vents or water pipes.

The features of both tools are completed by soft start, an electronic overload indicator, a PRCD protective switch and an overload clutch to protect user and machine.

The drill stands in detail
The GCR 180 Professional and GCR 350 Professional drill stands enable professional tradespeople to easily set the work angle before drilling and to precisely align the diamond drills. Both drill stands are suitable for vacuum and wall plug mounting and for drilling at an incline angle of up to 45 degrees. They are each operated using a handwheel which has three feed levers and can be fitted on both sides without the need for additional tools.

Complete solution: Everything from a single source
The diamond drilling system is complemented by comprehensive system accessories. These include mounting and vacuum sets for the drill stands, a pressurized water container, water collection rings with matching seal covers to minimize dirt during work, and a spacer plate for drilling holes of 300 to 350 millimeters with the GDB 350 WE Professional. In addition to this, Bosch’s range also includes the matching diamond core cutters for wet and dry drilling. The system comprises the “Best for Concrete” (wet), “Best for Universal” (dry) and “Standard for Universal” (dry) product series. Bosch therefore offers a coordinated complete system.

The diamond drilling system and the diamond core cutters will be available at specialist retail outlets from May 2015 onwards.
