WARNING
• To avoid serious injury, keep hands and
fingers away from the spinning bit during
drilling operations. Always be aware of
the bit when drilling.
• Before drilling, make sure the dowel
drilling jig is clamped securely to the
workpiece and the workpiece is secured
in a vise or clamp. Failure to do so
could result in unexpected shifting of the
project during drilling, which could cause
damage to the project.
TO USE
1. Align the workpieces exactly as they
will be joined. Make sure all faces and
edges are flush.
2. Decide how many dowels will be
needed to join the workpieces.
NOTE: The dowel drilling jig has
reference lines on the jig body for
centering two dowel holes or aligning
single dowel holes. In most cases,
two dowels are centered on the
narrowest workpiece.
3. Use a combination or try square to
draw a straight line where the two
workpieces will be joined. This will be
the line used to align the dowel drilling
jig to the workpieces. See Figure1.
NOTE: A straight edge can be used if a
square is not available.

be drilled based on the length of the
dowel being used.
5. Slide the stop collar onto the bit (do not
tighten) and place the stop collar onto
the jig body. Adjust the tip of the bit
to align with the desired drilling depth
on the depth scale and tighten the set
screw. See Figure 2.
