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". When using with brush
ring 2 maximum bit diameter is no 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". When using with brush ring 2
maximum bit diameter is no larger than 5".
Insert the vacuum hose 6 from the dust
extractor into the dust port 3 of the dust
extraction unit (Fig. A).
The Bosch dust extractor provides two
methods for connecting the hose to the dust
extraction attachment: sleeve nozzle 5 and
snap-in connector 4. To use the sleeve

nozzle slide the nozzle into the dust port of
the attachment. To use the snap-in
connector for more secure connection,
remove the rubber nozzle 5 from the vacuum
hose 6. Press the snap-in connector into the
dust port 3 until you hear the click (Fig. A).
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 dust extractor on and place the
attachment 1 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 2. Note: the suction from the dust
extractor 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. B). In
certain situations, where precise hold drilling is
required, first place the drill bit through the
opening in the brush ring 2, in the attachment
1, and position the tip of the drill bit in the
desired drilling location. 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.

manual for more details.
