Congratulations on the purchase of the Darex XT-
3000 Brad point Attachment. (LEX200) This
attachment consists of 2 pieces, 1 Sharpening
Fixture, SA16900BA and 1 - 3mm – 12mm Chuck,
SA16916TA. (The 12mm – 21mm Chuck,
SA16918TA is available
as an optional accessory)
Both components are
laser marked with a Brad
Point icon to minimize
confusion with other XT-
3000 attachments.
SETTING UP:
To sharpen a
Brad Point, you
will have to
remove the
standard
sharpening fixture
and replace it
with the X-Y
Table (LEX100).
The Brad Point Attachment works in together with
the X-Y Table. By now you are familiar with the
‘quick’ disconnect feature or your XT-3000. Begin
by removing the
current sharpening
fixture and replacing it
with the X-Y Table.
Secure it in place by
rotating the Docking
Lever CW. In much
the same manner,
secure the Brad Point
Sharpening Fixture to
the X-Y Table.
ALIGNING THE DRILL:
The alignment of the drill
happens in the XT-3000
Alignment. Loosen the
Timing Tube Lock lever and
position
the Tube
@ 118°.
Push the
lever down
to lock the
tube. Align
the drill as
you normally would.
SETTING UP THE X-Y TABLE:
Brad point drills are ground with the X-Y Table
positioned at the 180° mark. Loosen the Pivot
Lock Knob and rotate the X-Y Table to 180°. Lock
the Table.
SHARPENING:
With the XT-3000 OFF, place the Chuck in the
sharpening mechanism making sure the drill
DOES NOT contact the grinding wheel. If it does,
use the X-Y axis knobs to position the drill OFF
the wheel.
Turn ON your XT-
3000. Using the same
Axis Knobs, start to
move the drill into
the grinding wheel
while rotating the
Chuck. This fixture is
meant to re-sharpen
existing drills. During the sharpening process,
should you remove an excessive amount of
material, due to damage, it will be necessary to
re-align the drill and sharpen again. Refer to the
diagram
below for
examples of
proper drill
geometry.
