Need a 10 MM helicoil installation kit

5 posts in this topic

Hi guys.  I'm in need of a 10 MM x1.25 helicoil kit.  I have the inserts already.  Need the tap, and installation tool.  This is for the medium 10 MM threads.  (fine is 10x1.0MM, medium is 10x1.25MM, and course is 10x1.5MM)  Who here has bought a kit and never used it after that first time? I did manage to use a 5/16 twice, about 15 years apart. :-)   I'll rent it if you want it back.  Just don't want to spend $60 and never use it again.  Here is what I need.  Thanks,  JImChuk

Jim,  Unless there is a reason you cant use solid inserts instead of helicoils, like the walls not being thick enough, I highly recommend them.  They don't need the High $$ tap or tool, just the next size up for either standard or metric threads, and they have locktite already on the threads, or you can get them with little "fingers" that you drive home after screwing the insert in - They never come loose or strip out.  Check Grainger or MSC.  EDMO

Thanks for the reply Ed.  I found a helicoil set on ebay for $25 so I bought it.  The guy has a bunch of new old stock stuff that he is selling.  Hopefully it's not some Chinese junk.  I didn't want to make the holes any bigger than they already are.  JImChuk

Jim,  Either way, the holes have to be tapped out larger, unless you are just replacing a stripped helicoil.  I have several boxes of solid inserts, but sure that they are all American threads.  EDMO

Yes, I'm replacing some existing helicoil inserts.  JImChuk
