OMT Thread Repair Kit, 304pc SAE and Metric Helicoil Repair Kit with HSS Drill Bits Inserts Taps Break Off Tools, Rethreading Tools in 1/4" 5/16" 3/8" 7/16" 1/2" & M5 M6 M8 M10 M12 Sizes

Ordered for my 96 XJ Caliper bolts. Stripped since the previous person who did brakes over torqued. Worked out well. Have plenty other left over and many different sizes. Good set to have.

Seems to be a decent thread repair kit. Good price, fast delivery.

This has saved me so many headaches!

Overall, this kit is a fantastic value for the money. You get everything you need except a center punch, drill, cutting oil & tap socket/holder. Very handy for fixing broken bolts and/or for the individual in your life (maybe yourself, haha) who likes to engineer/invent/create/fabricate/build mechanical things. The helicoils themselves are of good quality and the tangs break easily after install. They include a lot of each size which is really nice. Also, the helicoil install tools and tang breaker tools are of nice quality. I also haven't had any issues with the thread taps, which have all left behind well made threads that the helicoils easily thread into. The only weak point in this kit if the drill bits. They are not of very good quality and one can expect to only get about 2-6 holes or bolts drilled out before they're dull. Take your time, erring on the lower side of speed when drilling and use "Boe-Lube" (my personal favorite) or cutting oil with your drill bit as you go. This will highly reduce the friction and risk of overheating the tip of the drill bit, rendering it more or less useless after. Overall, quite happy with the kit received for the money spent, a great value and excellent addition to my tool collection.

Worked like a charm to repair the ruined exhaust manifold threads on my deutz engine. This kit comes with everything you need, minus a t-handle for the tap.
