Metric Helicoil Thread Repair Kit: 131-Piece Heli Coil HSS Drills Inserts Taps & Tools M5 M6 M8 M10 M12 Automotive Engine Spark Plug Cylinder Insertion Rethreading Tools Universal Rethread Restorer

Firstly, this comes in a metal case, which is very welcome. I’ve used this a few times now and had no problems. The drills have worked absolutely fine, the taps too. No problem fitting the inserts though the tang at the bottom doesn’t always break off when it should, though it’s not caused a problem. So far it has made repairing damaged threads a breeze, the installed inserts have worked great. Last repair was a coolant pipe retaining bolt on an engine. It was quick, easy, the bolt went in first time after the repair was made and no leaks. Highly recommended!

Work great on my vehicle

Came with everything I needed.

the threads are more like tightly twisted springs so they dont always hold the way they should. so keep it in mind when you purchase. i bought it for a lifter bolt repair but it will not torque down and stay in place. but I think it would work good for other things that dont have a lot of repetitive force on them. other than that the drill bits work well and the threading tool cuts in nice and makes clean threads

This is a great product

Worked well. Was actually cheaper to buy the giant pack of coils than 3 individually.

I think we all come to a point in our lives where We need to put new threads into something. Today this kit helped me save a lawnmower that would otherwise require an entire cylinder head. I was pleasantly surprised to find that this kit had just about everything that you need to make it happen. I’m a big fan that it comes with multiple sizes. The instructions are very clear and I really appreciate it that it comes with the taps and the drill bits required for each size for several different sizes instead of just one for the same price. Each of the parts appear to be very high-quality Definitely a great addition for my toolbox. The only downside of the kit is that it doesn’t come with a t-handle, but that can be purchased separately or you can just run it from a drill like some people do. Five stars would purchase again.

It work and way cheaper than parts store

Great product.

Thankyou Amazon this thread repair kit is awesome. I am a happy customer.

Las diversas medidas serán muy útiles .

I damaged my cycling shoes cleat thread and was looking for a DIY solution as the shoes is an expensive brand , was not sure of the helicoil fix , i did all the research i need and decided to go for it , i ordered this helicoil kit that includes the M5x0.8 size that am looking for , when received the order i was really impressed with the high quality of the box and the tools included, the helicoil, threading tool , helicoil insert and the helicoil bags that come with each size , i only needed the M5 size but the kit includes multiple helicoil sizes and tools for each size. The procedure i was going to do on the shoe is like a surgical and critical as there is a carbon insole and i need to be very careful while drilling, i was hesitant to start it but then i went for it and did the job. The result is new thread better and stronger than the original thread . Very happy with the result, cleat are back again in place with very tight screw like new .. i recommend this kit for whoever is looking for a thread repair option just research it first and plan your procedure according to the job. One last thing the price of that kit of 48 AED is the cheapest among the online after checking different options, quality wise this is killer kit for someone who is not looking for half solutions… solid 5 stars rating
