Basic X-Lock Operation - Bosch PROFACTOR GWX18V-13C Operating/Safety Instructions Manual

The X-Lock system is a combination of
patented tool mount and accessory de-
signs that provide the operator with fast
accessory changes. Available on select
Bosch angle grinders, X-Lock allows tool
free installation and removal of grinder ac-
cessories (grinding, cut-off wheels, wire
brushes, sanding discs, etc.). The X-Lock
system is a replacement for the traditional
method of attaching grinder accessories.
Traditional grinders have 5/ 8"-11 thread-
ed spindles that require a nut and backing
flange to hold the accessory in place. To
replace an accessory, a wrench is used to
loosen or tighten the nut. X-Lock equipped
grinders have a tool free interface system,
eliminating the spindle, backing flange and
lock nut.
The X-Lock interface has a tool component
– X-Lock Accessory Mount, and an acces-
sory component – typically an Accessory
X-Lock Mounting Hub. The two compo-
nents have keyed alignment contours,
which help to ensure correct assembly of
accessory to tool.
The X-Lock Accessory Mount consists of
a round base, clamping height gages and
locking mechanism, which activates the
clamping tabs. X-Lock equipped grind-
ers can only use X-Lock accessories since
the specially designed X-Lock Mounting
Hub matches the contours of the X-Lock
Accessory Mount on the tool (See figure
2). However, select X-Lock accessories are
backward compatible with the traditional
threaded spindle design.
Attachment of the X-Lock accessory to the
X-Lock Accessory Mount on the grinder
requires alignment of the mounting hub
with the accessory mounting mechanism.
Once the Accessory X-Lock Mounting Hub
is aligned, and pressed against the base of
the X-Lock Accessory Mount, the locking
mechanism is activated. This causes the
two opposing clamping tabs to lock the ac-
cessory to the grinder. An audible 'click' in
combination with the alignment of the flat
surface of the Accessory X-Lock Mount-
ing hub with the Clamping Height Gages
means the accessory is firmly attached to
the tool. To remove the accessory, a lever
