The X-Lock system is a combination of
patented tool mount and accessory designs
that provide the operator with fast
accessory changes. Available on select
Bosch angle grinders, X-Lock allows tool
free installation and removal of grinder
accessories (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 threaded
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
accessory component – typically an
Accessory X-Lock Mounting Hub. The two
components have
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 grinders
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
accessory to the grinder. An audible 'click'
in combination with the alignment of the
flat surface of the Accessory X-Lock
Mounting hub with the Clamping Height
Gages means the accessory is firmly
attached to the tool. To remove the
accessory, a lever on the grinder gearhead
is actuated which will release the locking
tabs, allowing the accessory to be detached
from the tool. (Fig. 3)
