HLS | Drill Jig Operating Instructions
7. Drill 16mm counter bore (Heavy wall only)
With the depth setting nut correctly set, the 16mm
counterbore tool will drill approximately 2mm into a 50mm
rail, leaving a 16mm counterbore. The required depth of
the counterbore may vary based on the diameter of the rail
that you are installing into; or batch variations in the pucks
supplied.
Important:
Test the counterbore depth after tapping the
hole by installing a puck from the batch you were supplied.
You may need to adjust the depth to better suit your rail/
install surface, and/or the batch of pucks.
8. Tap hole
The tapping process will cut an M16 x thread into the 15mm
hole. If you are installing the Heavy wall pucks, your holes
should have the 16mm counterbore as well as the 15mm
through hole. The tapping process should not effect the
16mm portion of the hole.
1. Insert the tapping tool (see step 4. Attach/detach the tool)
2. Push the tapping tool up until it engages with the hole.
3. Activate the drill in the clockwise gear until the tap is
cutting to the maximum diameter, then stop the drill.
4. Set the drill to anti-clockwise, then activate until the tap
clears the hole.
9. Remove clamp, de-burr, check
1. Remove tapping tool, and clean.
2. Remove the pipe clamp from the rail, and clean.
3. File the hole with the
fi
le supplied to remove burrs,
and swarf.
4. Screw in a puck from the batch supplied to test the
thread (and the depth of the counterbore if this is your
fi
rst hole).
5. Go to next hole.

Drilling steps
1. Check that the 10mm driver bit is in the drill, and the
chuck is tight.
2. Check that your drill is set to the lowest gear, and set it to
the clockwise direction.
3. Put on eye protection/safety glasses.
4. Engage the drill, and continue cutting until the depth
setting nut contacts the end cap, and you hear the clutch
engage. The clutch will stop the cutters from rotating
when the depth setting nut contacts the end cap.
5. Switch the drill to reverse, and back the cutter out until it
clears the rail.
