Helicoil thread insert tools are used for installing helical threads into a drilled hole or repairing a stripped screw or bolt thread. The brand's threaded mandrels are designed for installation of large coarse-pitched (and 2-56, 3-48 & M2.2) inse...rts and guide them into the tapped hole easily and quickly. Helicoil tang break off tools are used with inserts to remove / eliminate their driving tangs for preventing interference with the end of the assembled bolt.
