Re: Heli-Coil Usage

I have installed a 7/16-20 helicoil many times in Packard blocks with perfect success to date. I have even done it without removing the head as the hole through the head is a great oversize to guide the drill bit for a nice straight shot. Its a little painful to buy the Helicoil set to do one, but rather necessary. Helicoils were good enough for instruments undergoing the rigors of launch on the spaceshuttle--they are good enough for me. But do use some sealer!
