Helicoils create new threads on stripped bolts. A Helicoil kit typically consists of several helicoils, a thread tapper and a few necessary tools. The kit may or may not include the helicoil drill bit. If it is necessary to buy the drill bit, it is imperative to purchase the exact size needed to work with the kit. It is also important to buy a metal bit and not a wood bit.
