Congratulations on the purchase of your Darex
XT-3000 Large Drill Attachment. (21 mm—30
mm) As part of the assembly (see picture from
left to right) you should have a SA16565XA Large
drill alignment, SA16575CA Sharpening fixture,
and SA16500TA Large Drill Chuck.
By now you are familiar with the ‘quick disconnect’
feature of your XT-3000. Start by placing the
Large Drill Alignment on the top of your XT-
3000. Rotate the ‘Docking Lever’ clockwise to
securely lock the fixture in place. In a similar
manner, remove your current sharpening fixture
and replace it with the Large Drill Sharpening
Fixture.
Determine the point
angle of the drill to be
sharpened and adjust
both the sharpening
fixture and alignment to
that point angle. The
Sharpening fixture is
adjusted by pulling the
red lever towards
(counterclockwise) the
operator and sliding the
fixture to the point angle
desired. Lock the fixture
by returning the red lever to its original position.
The alignment is adjusted by
rotating the black lever
located on the front of the
alignment fixture. As per the
decal, rotating the lever
towards the operator will
reduce the amount of relief
ground onto the drill and
pushing the lever away from
the operator will increase the relief. Placing the
pin at the midway point on the decal is a good
starting place for 118° drills. For 135°-150° drills
start with the alignment 2 marks towards the
operator. You can set the alignment at any setting
necessary to achieve the amount of relief desired.
Place the drill in the chuck and turn the chuck
knob clockwise until the drill slides freely through
the chuck jaws. Next slide the Chuck and drill into
the alignment rotating the chuck until one of the
‘cam dogs’ aligns with the
mating ‘notch’ in the fixture.
You will notice the opposite
‘dog’ aligns with a reference
mark machined into the
alignment fixture.
Now push the drill through the chuck until it
contacts the stop. Rotate the drill clockwise until
