131PCS Thread Repair Kit, HSS Drill Helicoil Repair Kit SAE&Metric M5 M6 M8 M10 M12 Kit

Very nice set. Good quality would recommend 👍

A fairly comprehensive kit of many sizes, enabling you to make repairs to stripped threads or repair threads on bolts you have had to drill out. Note, this is not a bolt removal product. It allows you to insert a new thread "liner" in to a hole where a thread has been stripped or drilled out. There's many sizes, depending of which kit you buy, with a good supply of the helicoil inserts.

Good quality and value

This kit it perfect tool to have in your tool collection I’ve used it a couple of times to replace damaged threads on items very simple to use and everything is in the kit

I’ve not used this yet but it seems like a pretty decent set. I would say the only downside to this set is it’s not got 3 and 4mm if it had them it would have pretty much everything although you can buy them separately it would be nice to have them in the set. Of course it would cost more but me personally i would be happy to pay more. Also the drill bits are not the best but they are not going to be as large decent drill bits are quite expensive. The box is quite robust which is a good thing and i would say it worth its money.

Fantastic kit, I used to repair a stripped M8 injector clamp bolt, drill bit glided through the alloy head with ease, as did the tap provided and installing the Heli coil with the tool was easy. Being able to use my original bolt was crucial and this kit allowed me to do just that Would highly recommend.

excellent bit of kit.

All the pieces don’t fit in their places properly and some were greasy when they arrived. Works fine and does the job but can get same set for half the price.
