Looks like a good set. I needed it as soon as I got it. I drilled recommended 5/16" holes for 3/8"-16 threads. I sprayed some lube on it while turning the faucet on and off to get the shavings off. As soon as it got tight I felt a bang! Smaller threads on the large faucet handle started the strip. I ended up using an adjustable wrench to finish this hole. I fixed it as I had the correct stamp and wanted it done. I took the handle out and missed the appropriate thread die by 1/4 inch or so. I also drilled a hole in the jaw for it to work as a slip fit and used a larger thread for the threaded retaining jaws to work. beat. This allows the jaws to work, but since the body of the handle feels like aluminum I'm not sure how long it will last. In general, the number of taps and dies is good. hard to read on plastic. The taps look cheap when used. The thread I cut was fine but looked a bit rough compared to what I was able to do at work. The matrix I used on the handle worked. good as his grip is. Would I buy this again? I'm not sure. I think I would look for something better. .
