DIY stripped thread repair: Helicoil vs Amazon knock off kit

[eddythehead]

I used a cheap brand heli coil at work and the heli coils varied in size and some tapered a little. Had nothing but trouble and scrapped a bunch in the process. I then switched to name brand and no issues. With the cheap brand, as long as you have no trouble installing them, they should be fine.

I have the cheap kit. It does work and is useful. However the insertion tools are fairly weak

I got this same kit here in Thailand for $16

I bought a bigger set on Amazon $70. I'll see how it works tomorrow. Gotta drill out two broken studs, drill and rethread with the inserts.

So I had an oem m12 drain plug on my victory I was able to extract it removing the threads. For a temporary fix I put in a m12.1 x 1.5 x 15mm what size time sert do I need now that the drain hole is .10 bigger then it was. Can I still drill it out with the m12 kit or do I have to go to an m13

Did you use a hand drill? I’m about to do this exact job with the exact kit on 4 bolts.

[escapingthematrix]

I’m about to do time sert on my drain plug people are telling me not to do the helicoil on it what do you suggest

I bought both too, but I have a random size that isn’t in the large one.

Amazon tool quality is most of the time really bad and bevor I get that from amazon and it brakes in the engine I get the better one with no Problems. So we in Germany "say if you buy cheap you buy twice".
