PH/JIG/M
-8-
Do not place the drill tip against the
component until the drill is at full
speed.
Drilling the Pocket Holes
Boring the counter-bored hole involves drilling
with a stepped drill into one of the joint pieces.
n
Once the collar depth and base is set, clamp
the jig to the timber tightly using an ‘F’ clamp
or bar clamp.
Use a high drilling speed to increase
drill life (2000 rpm or higher).
Place the drill bit into the top section
of the drill guide hole before spinning.
Keep the drill bit sharp.
Make sure drill bit is held in chuck
securely. If the drill spins loose in the
chuck the shock can break the drill
bit tip.
Make sure the jig and component
are clamped securely before drilling.
n
Fit the drill bit with depth collar already set
into the chuck of the drill used.
n
Place drill bit into top section of the bush hole
in drill guide. Do not place the drill tip against
the component.
Do not push hard on the drill until the
drill pilot tip of the drill bit is fully into
the work piece and the counterbore
section is actually cutting.
Pocket Hole Spacing
When boring framing material, two pocket holes
should be used to keep the timber from twisting.
When working with long pieces of timber to
create a board (jointing edge to edge) to make
a table top for example, single pockets can be
drilled at between 150mm to 200mm centres.
n
Switch on drill at full speed (clockwise
direction) and drill into the component until the
collar touches the bush. Gently pulling drill in
and out whilst drilling will allow wood chips to
clear more easily.
n
Once depth is reached switch drill off and
withdraw drill bit from drill guide.
n
Repeat for other pocket hole and then remove
component.
n
Repeat operation for the remaining pieces.
