Helicoil type inserts larger than 1.5in diameter?

[joshuabass]

I have been researching all day, but it seems industry stander threaded inserts all stop around 1.5in diameter. I am looking to repair some 2.00in diameter threaded holes and have run out of places to look. Does anyone know of threaded inserts that go this large? Otherwise we may be machining custom inserts.

Why don't you call Helicoil corp. They have been doing this for at least 50 years. They may give you some insight at least.
