Retrofitting
The GDB 1600 WE can also be equipped with a ex-
tractor head 15.
The reequipping of the GDB 1600 DE for wet use is
not possible for safety reasons. A special coding on
the machine and drill head ensures that this cannot be
done.

Connected hoses, shut-off valve or other ac-
cessories should not hinder the drilling
process.
Inserting and Removing Tools
Use wet or dry core drilling bits only for the in-
tended application in each case.
Color Coding:
Bosch wet core drilling bits
Bosch dry core drilling bits
The core drilling bits are equipped with the SDS Sys-
tem:
Special = Insert
Direct = Turn
System = Seated
Before inserting, clean SDS-DI tools and lightly grease
the insertion end.
Insert the dust-free tool in the tool holder 12, twist and
push in until it latches. The tool locks itself. Check the
locking by pulling on the tool.

To remove, pull the locking sleeve 11 to the rear (A),
