Just what the PSD doctor ordered. I give 4 stars rather than 5 just because the bit needs/should be a 3/8 shank; most of us don't have 1/2 inch 90-degree right angle drill attachment. Like other, I, too was confused on which tap was the starter and which was the finisher.

This product will save you thousands of dollars and time simple to use and great results very pleased with this product.

Works like a champ. Purchased a 3/8 drive drill bit to fit my dewalt right angle cordless as the 1/2” chuck right angle I do not have. Fast shipping and customer service great

Ran into a problem after the initial Hpop repair, even with factory torque spec of the mounting bolts, the bolts became loose, removed the hpop again only to find the aluminum thread came out with the bolt, Ordered this kit and bought a 90 degree air drill, tap sockets for a 3/8 Drive ratchet!
Making sure you drill and tap as straight as you can is critical, inserts went in with no problem, used some extra loctite, hpop went on and bolts took the factory torque spec with no issue. Kit has been installed for a month with no leaks around hpop, thanks Riffraff for a great repair kit!

good repair kit,but had to make drill bit fit in my air drill by grinding on it.

Drill bit needs to be for a 3/8 Drill instead of 1/2.

Much like the rest of riff raffs products worth every cent.

Awesome product, 100 times better than a helicoil!

After i stripped out my hpop mounting bolt threads, i found myself looking for a solution and this kit was it! Only inssue i had was not being sure which tap the instructions was refering to as the," bottoming tap" there are two taps included and i wasnt sure which one was which. This product solved my problem and i look forward to using more RiffRaff products!
