The complete solution: Diamond drilling system and diamond drill bits from a single source
GDB 180 WE Professional for holes with 180 mm diameter
The GDB 180 WE Professional weighs 5.2 kg and has a 2000 W motor with 2-speed gearbox, yet it is extremely light and powerful. Also worth noting is the 180 mm hole diameter, which is the maximum hole diameter for this power class. The tool can be hand held and mounted on the drill stand of the GCR 180 Professional. And thanks to the small-angle size, work close to the wall is possible.
Furthermore the GDB 180 WE Professional is characterized by extreme robustness: The gearbox is not lubricated by grease, but by an oil bath. Optimal gear lubrication guarantees a high degree of efficiency and a long service life. The cast aluminum housing and the flexible and very strong cable make for a long tool life.
The GDB 180 WE Professional is suitable for a wide range of applications. Designed for drilling with or without oil cooling. Typical applications are drilling holes for electrical outlets, fixtures, conduits and cable entries, and drilling holes for HVAC components. Two built-in spirit levels simplify precise alignment of the tool while drilling any hole.
The GDB 350 WE Professional for holes up to 350 mm in diameter
The GDB 350 WE Professional is designed for holes up to 350 mm in diameter. It has a power output of 3200 W and so a very high power output. The oil-filled gearbox, the cast-aluminum housing and the flexible and very robust cable ensure a long service life, just as in the case of the other, more compact model. The GDB 350 WE Professional is additionally equipped with an integrated oil pump for optimum lubrication of the gearbox and for vertical drilling.
The diamond drill bit is supplemented with a drill stand of the GCR 350 Professional. Working angle adjustable on scale GCR 350 Professional assures exact alignment of tool while drilling. Speed and torque can be flexibly adjusted to the task at hand thanks to the 3-speed gearbox. The GDB 350 WE Professional is suitable for wet drilling in reinforced and unreinforced concrete, as well as in masonry. It is suitable, for example, for making apertures for supply and return lines, drilling vents or holes for water pipes.
Both tools are complemented by a soft start, electronic overload indicator, PRCD safety circuit breaker and a safety coupling for the protection of the user and the tool.
More information about drill stand
The drill stands of the GCR 180 Professional and GCR 350 Professional allow craftsmen professionals to easily adjust the working angle before starting to drill and to precisely align the diamond drill bit. Both drill stands are suitable for vacuum and anchoring as well as for drilling holes with an angle of inclination of up to 45°. Each of them is adjustable by means of a handwheel, which has three lever handles and can be moved from one side to the other without using additional tools.
The complete solution: everything you need from a single source
The diamond core drilling system is complemented by a comprehensive range of system accessories: These include e.g. anchoring/vacuum anchoring kits for the drill stand, water pressure tank, water collection rings with suitable sealing covers to ensure a clean workplace, and a spacer plate for drill holes from 300 to 350 mm in diameter with the GDB 350 WE Professional.
Bosch also offers suitable diamond drill bits for dry and wet drilling. The system includes the product lines “Best for Concrete” wet drilling , “Best for Universal” dry drilling , and “Standard for Universal” dry drilling . Thus Bosch offers a complete solution with components that are perfectly matched to one another.
