Disconnect the plug from
the power source before
making any assembly, adjustments or
changing accessories. Such preventive
safety measures reduce the risk of starting
the tool accidentally.
The HDC200, HDC250 Bosch dust extraction
attachments are designed to be used in
drilling applications in concrete and masonry
type materials.
The HDC200 is optimized for use with drill bit
diameters from 1/4" to 1-3/8". The maximum
bit diameter is 2-5/8" (brush ring must be
removed for diameters larger than 1-3/8").
The HDC250 is designed for use with large
diameter bits including diamond and carbide
tipped core bits. It is optimized for bit
diameters from 2-1/4" to 5". The maximum bit
diameter is 6" (brush ring must be removed
for diameters larger than 5").
Insert the vacuum hose from the vacuum into
the dust port of the dust extraction unit (Fig.
2).
The Bosch vacuum hose comes with a
sleeve nozzle attached to a snap-in
connector. The sleeve nozzle provides the
quickest and easiest connection of the
nozzle to the attachment. The snap-in
connector provides a more secured
connection. To use the snap-in connector,
remove the rubber nozzle from the vacuum
hose. Press the snap-in connector into the
dust port until you hear the click.
Dust port adaptors are also available to
connect the Bosch dust extraction
attachment to any common size vacuum
hose. See Boschtools.com for details.
Turn the vacuum on and place the
attachment on the wall (or the floor), over the
desired drilling location so that the center of
the hole lines up with the center of the
opening of the brush ring. Note: the suction
from the vacuum will hold the attachment in
place on the work surface. Place the drill bit
through the opening in the brush ring in the
desired drilling location and drill the desired
hole (Fig. 3). Follow all tool safety and
operating instructions.
Note: for best results, continue running the
tool even when removing the bit from the
hole. The combination of the vacuum with
the spinning motion of the bit helps remove a
majority of the dust from the hole.
