Selecting drill chucks and tools
Hammer drilling and chiselling require SDS-plus application
tools that are inserted into the SDS-plus drill chuck.
For drilling without impact in wood, metal, ceramic and
plastic as well as for screwdriving, tools without SDS‑plus
are used (e.g. cylindrical shank drill bits). For these tools, a
keyless chuck or a keyed chuck are required.
Changing the drill chuck
Inserting/removing the keyed chuck
GBH 18V-26
You must use a suitable drill chuck (keyed or keyless chuck,
accessories) to work with tools that do not have SDS-plus
(e.g. cylindrical shank drill bits).
Fitting the keyed chuck (see figure B)
– Screw the SDS-plus shank (23) into a keyed chuck (22).
Secure the keyed chuck (22) using the securing screw
(21). Note that the securing screw has a left-hand
thread.
Inserting the keyed chuck (see figure B)
– Clean and lightly grease the insertion end of the shank.
– Insert the keyed chuck with the adapter shank into the
tool holder with a turning motion until it automatically
locks.
– Check that it is locked by pulling the keyed chuck.
Removing the keyed chuck
– Push the locking sleeve (5) back and remove the keyed
chuck (22).
Removing/inserting the quick-change chuck
GBH 18V-26 F
Removing the Quick-Change Chuck (see figure C)
– Pull back on the quick-change chuck locking ring (6), hold
it in this position and pull the SDS plus quick-change
chuck (2) or the keyless quick-change chuck (1) out from
the front.
– Once the quick-change chuck is removed, protect it from
dirt.
Inserting the quick-change chuck (see figure D)
Use only model-specific original equipment and pay
u
attention to the number of identification grooves
(25). Only quick-change chucks with two or three
identification grooves are permitted. If an unsuitable
quick-change chuck is used, the application tool can fall
out during operation.
– Before insertion, clean the quick-change chuck and lightly
grease the shank.
– Wrap your whole hand around the SDS-plus quick-change
chuck (2) or the keyless quick-change chuck (1). Use a
turning motion to push the quick-change chuck into the
drill chuck holder (24) until you hear it click into place.
– The quick-change chuck is automatically locked. Check
that it is locked by pulling on the quick-change chuck.
