2. Fit the selected tap (4) in a suitable tap
holder/tap wrench (sold separately in
Jula department stores and at
www.jula.com) and make new threads
as deep as necessary to ensure that the
replacement thread (5) does not extrude
over the surface of the thread hole.
NOTE:
Use a suitable cutting fluid and twist back the
tap half a turn for each full turn clockwise to
ensure that the threading is effective.
– For blind holes, set the position for
the depth adjustment collar (1) on
the installation tool (2) so that the
tap does not seat and stick out over
the upper surface of the thread hole.
Make sure that the thread insert tang
(A) comes in the slot in the
installation tool (2).

3. Twist the insert in the hole to the requisite
depth and remove the installation tool (2).
4. Use a suitable punch and hammer to
remove the tang.
