Operation
Determine the size of the threaded hole that you want.
Drill out the hole, using the included drill bit to the
proper size. Refer to the Size Chart on page 1 of this
manual. When drilling metal parts, use a little cutting
oil to lubricate and cool the drill bit.
If you are going to make the threaded hole larger
than the original, drill it out in steps, using a series of
increasingly larger drill bits until the desired size is
reached.
