Selecting Drill Chucks and Tools
For hammer drilling and chiselling, SDS-plus tools are re-
quired that are inserted in the SDS-plus drill chuck.
For drilling without impact in wood, metal, ceramic and plas-
tic as well as for screwdriving, tools without SDS-plus are
used (e.g., drills with cylindrical shank). For these tools, a
keyless chuck or a key type drill chuck are required.
GBH 2-26 DFR: The SDS-plus quick change chuck 2 can easi-
ly be replaced against the quick change keyless chuck 1 pro-
vided.
Changing the Key Type Drill Chuck
(GBH 2-26 E/RE/DE/DRE)
To work with tools without SDS-plus (e.g., drills with cylindri-
cal shank), a suitable drill chuck must be mounted (key type
drill chuck or keyless chuck, accessories).
Mounting the Key Type Drill Chuck (see figure C)
– Screw the SDS-plus adapter shank 20 into a key type drill
chuck 19. Secure the key type drill chuck 19 with the se-
curing screw 18. Please observe that the securing
screw has a left-hand thread.
Inserting the Key Type Drill Chuck (see figure C)
– Clean the shank end of the adapter shank and apply a light
coat of grease.
– Insert the key type drill chuck with the adapter shank into
the tool holder with a turning motion until it automatically
locks.
– Check the locking effect by pulling the key type drill chuck.
Removing the Key Type Drill Chuck
– Push the locking sleeve 5 toward the rear and pull out the
key type drill chuck 19.

rear, hold it in this position and pull off the SDS-plus quick
change chuck 2 or the quick change keyless chuck 1 to-
ward the front.

contamination.
Inserting the Quick Change Chuck (see figure E)
– Before inserting, clean the quick change chuck and apply a
light coat of grease to the shank end.

change keyless chuck 1 completely with your hand. Slide
