From the people running this tool

Worked well

Worked very well for fixing a stripped hole for a bolt that held on the idler pulley on my wife’s car. The kit included everything I needed and everything went smoothly, first time I’ve done something like this. It seems sturdy and the tools felt like good quality.

Worked great

Worked beautifully on the alternator bracket bolt hole that was in the side of my aluminum engine block that was stripped out. Using the included drill bit, it was easy to use and install. It’s held up solid for months. Definitely beats $60 for a helicoil at a parts store.

Straight units

What a kit. I want one in every size. Every tool in the kit worked great. Made installation of my bar studs are stripping then out easy. This kit was fully compatible came with every piece I needed for the entire job minus the drill*. Everything was a perfect fit, the system was solid. Sealed right. What a versatile kit I can't wait to use on other projects
