HLS | Drill Jig Operating Instructions
5. Drill 15mm hole
Drill selection
We recommend the use of a battery drill with a low speed
of approximately 300rpm. You may need to refer to the
technical speci
fi
cations of your drill to determine suitability.
How the drill jig works
The drill jig takes all the hard work out of drilling the hardest
of metals and stainless steels. Upon ‘power on’ the drill,
when attached to the drill jig will:
•
Engage the drive for the cutters
•
Move the cutters into the cutting surface
Drilling steps
1. Insert the 10mm driver bit into the drill, and tighten the
chuck.
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 15mm bit
breaks through.
5. If
fi
rst hole: go to depth setting (next step)
6. If
NOT
fi
rst hole: switch the drill to reverse, and back the
cutter out until it clears the rail.
Depth setting steps
After you have broken through on the
fi
rst 15mm hole,
stop drilling and do the following:
1. Screw the drill inwards by hand until the 16mm
counterbore tool is touching the rail.
2. Holding the drilling tool to keep it stationary, screw the
depth setting nut up until it contacts the end cap of the
thread cover.
3. Use the following instruction based on thread type:
i. Thin Wall (TW) - drill 15mm hole only
a. Unscrew the drilling tool at least 2 turns back from
this position.
b. Holding the drilling tool to keep it stationary, screw
the depth setting nut up until it contacts the end cap.
c. Insert set screw such that it aligns and engages
with the milled slot in the thread, to lock the depth
setting nuts in place.
ii. Heavy Wall (HW) - drill 15mm with 16mm
counterbore
a. Holding the drilling tool to keep it stationary, un-
screw the depth setting nut two full turns (a 2mm
gap results - shown above)
b. Insert set screw such that it aligns and engages
with the milled slot in the thread, to lock the depth
setting nuts in place.
6. Depth setting (once only)
What is depth setting?
The depth setting process will limit the travel of the drilling
tool. The depth setting will allow you to:
1. Drill a 15mm hole only (for thinwall (TW) pucks)
2. Drill a 15mm hole with a 16mm counterbore (for heavy
wall (HW) pucks)
3. Set the depth of the counterbore to match your batch of
pucks
