🔧 HHIP 1011-0081 31-Piece 1/4-20 Helical STI Thread Repair Kit: Fix and Strengthen Threads with Precision Review

Pretty cheap quality drill bit broke on first hole. If you have a good set of bits, still cheaper than the competition but not perfect imo

If you care about your project, whatever it is, don't buy this kit! The moment I started the insert in the hole broke like it was porcelain and not "stainless steal" and it kept breaking into small pieces.

Good set as it comes with a drill and everything you need except the red screw lock. Use screw lock and it works great. Has a metal tool for inserting and a metal bar for breaking the edge. Worked great.

Had to fix one of the valve cover threads on a 2004 Sportster 1200 and worked great. 4 stars because the insertion tool forks are broken. Luckily I had a thin needle nose to complete the repair.

It arrived quickly and worked essentially as advertised. The drill bent immediately. And I want the tap to cut the thread a little closer to the end of the hole. Like a second lower faucet. The threads appear to tighten as the screw deepens.

Apparatus seems fine. I have used other manufacturers' heli coil kits which were more comprehensive. I would have preferred the threaded insertion tool to the simple, thin and straight wand they sent and the shaft removal wand which is the inner diameter of the spiral coil instead of the thin one they sent.
