Diamond drilling system shines The new diamond drilling system from Bosch is a powerful complete solution for core drilling. This allows HVAS installers and diamond drilling specialists to achieve a fast drilling rate, even at large diameters, in masonry and concrete.
RANGE OF APPLICATIONS The GDB 180 WE Professional covers a range of applications.
HIGH FLEXIBILITY
It is suitable for dry and wet drilling. Two bubble vials integrated into the housing make it easier to align the tool precisely for each drilling application.
The system comprises the GDB 180 WE Professional and GDB 350 WE Professional diamond drills, as well as the GCR 180 Professional and GCR 350 Professional drill stands, Campbell Mhodi, Bosch Professional Power Tools senior brand manager explains. ‘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 says.
Typical applications: • Core drilling for electrical installation sockets and reinforcements • Cable and tray feedtroughs • Breakthroughs for HVAS installations
HAND-HELD-TOOL FOR LARGE DRILLING DIAMETERS The GDB 180 WE Professional is exceptionally lightweight at only 5.2 kilograms, with a powerful 2000 W motor and two-speed gearbox. At 180 millimetres it also offers the largest drilling diameter in this performance category. The major advantage is that it can be used as a hand-held tool, together with the GCR 180 Professional drill stand. When both products are used together, the GDB 180 WE Professional can be used close to the wall thanks to its small corner measurement.
EXCEPTIONALLY ROBUST The GDB 180 WE Professional is 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 3200 W GDB 350 WE Professional is designed for large drilling diameters of up to 350 millimetres. As with the smaller model, a long lifetime is ensured by oil bath lubrication of the gearbox, a die-case aluminium housing and a flexible, vbreak-resistant cord. To ensure the gearbox is completely supplied with oil even during vertical drilling, it 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, enabling the tool to be aligned precisely during drilling. The speed and torque can be adapted flexibly to the drilling application, thanks to a three-speed gearbox.
