Only thing i had a problem with, The drill bit should be 3/8 step down bit. 1/2 inch to big for my angle drill.

I only gave this product three stars because of the difficulty in being able to chuck up the drill in a 90 degree drill motor that will not cause interference with the passenger side of the block in aligning the bit with the hole. I ended up using a 90 degree pneumatic aircraft drill and purchased a jobber length drill bit that was turned down to fit a 3/8” chuck. In order to use this setup with maximum precision I removed the HPOP reservoir and the spider. This constituted more work than I originally anticipated, however, the final results were excellent. There is no spec given for the optimal setting of the drill stop so you need to take care in setting it correctly. A micrometer and depth gauge were of great help. Otherwise, the parts included in this kit are of the highest quality and used carefully this kit will make an excellent repair of stripped out HPOP mounting threads. Good luck!

Good quality taps and drill bit . You can get the inserts at just about any local hardware store for .60 cents a piece . That being said . It was nice knowing I had the correct tooling for the job

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.
