They work, and this is better than buying a set containing sizes I'll never use.

This is the 2nd brand of this tool I have purchased and while this one was less expensive than the other brand the durability was better and allowed me to complete the job easily which gives a better value for the money and the fitment and size were perfect as advertised.

I stripped a thread on the timing tensioner, got a helicoil set thread repair from O’Reiley for about $75, then I tried Amazon, found this fantastic deal with quick shipment promise. So I bought this and got it pretty fast about 2 days. The drill bit and tap are made in from high quality material, they did the job, now I can return the O’Reiley. Big money savings!

I got the M8 thread repair kit. It can be difficult to find the exact drill bit and tap needed for M8 helicoil inserts. You probably won't find them in a standard drill bit set or tap set. This thread repair kit makes it easy by including the exact size of drill bit and tap necessary. The kit is very easy to use. First, drill out the damaged thread, use the tap on the newly drilled hole, thread in the helicoil insert using the included installation tool, then break off the tab using the included tool. It took my less than five minutes to complete a repair. The only things you need to already have is a drill and a tap wrench. If you don't have a tap wrench, search the internet for alternative tools to use. The price is very good for this kit.

If you have stripped threads this kit works as intended. I would definitely buy this again.

I needed these to "re-thread" some holes on my wife's Kia's intake manifold. The toughest part of the installation was using the insertion tool included with this order. The tool allowed me to start the insertion, but as you turn it and get closer to getting the helicoil to the right depth, the fingers on the tools begin the bend inward, which then grasps the crossbar on the helicoil, when then makes removal of the tool nearly impossible. I had to remove the helicoils several times to straighten out the fingers on the tools to continue the job. Eventually I got all of them (4) done, but that tool is all but worthless. They need to make the tool's fingers more robust.
