25Pcs M7x1 Thread Repair Kit Stainless Steel Twisted Drill Wrench Threaded Insert Tap Insertion Tool

Great thread repair and cleaner for VW/Porsche VR6

Recommended 100% I used on cylinder head

Kit worked fine for the job.

Worked perfectly to hold the valve cover to the cam caps on my 97 Suzuki GSF1200 Bandit. Wrecked one insert due to lack of pressure when attempting to thread into tapped threads, but otherwise worked great. Just make sure they are drilled straight and you shouldn't have a problem. Will see how they hold up once I get some heat cycles in them, but seemingly fixed my stripped cam caps.

I've never installed a helicoil before (so can't really comment how these parts compare to any other kit) but I got it installed in an aluminum bike part and only ruined one insert.

I ordered this Helicoil kit to repair a stripped-out cylinder stud mount on my Vespa engine. This is a critical application that has to withstand the stress and strain of the engine firing. Even though the stripped hole was in a hard-to-reach location, the sharp drill bit and tap centered and straightened themselves in the aluminum case. I got a perfect repair and was riding again in short order. Some experience with tools is necessary for good results, but these tools are good enough to get the job done on a shoestring budget.

Spring twisted up and broke off inside the head of my motor. Ended up having to drill it out as well, and oversize the hole because of this (which is what I did not want to do in the first place). Cheap Junk do not recommend.

Thread Repair Kit is a must to fix it right the first time. I have to fix 3 of it all done correctly with this kit.

Very affordable and I met my expectations. I would recommend it.
