the appropriate sized drill bit, drill a hole deep enough
to allow the pin and pilot of the tap (step four) to
reach its proper depth (the exact depth will vary depending
on which size dowel you are installing).
the hole created in step one won't be a perfectly clean
hole, and in fact will be a little undersized, you must
use a reamer to finish the hole. The result will be
a very smooth, consistent, dimensionally accurate hole.
you must counterbore the hole. This tool is designed
with a pilot end to perfectly align itself in the center
of your hole before boring a perfect concentric bevel
on the top of your hole. In order to prevent boring
your bevel too deep, the counterbore has a cam on the
side, allowing you to manually set the depth of your
the tap to cut the threads in the hole beneath the bevel.
With a tap wrench attached, you can manually turn the
tap to create the threads.
