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,

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.
