Good hvac repair

Actually, I ended up re-shaping the boring tools that I used from this set, as they seemed a bit awkward to use, especially on larger tubing, but they did do the job I bought them for. The transition in size was a bit abrupt, so ground the edges on my bench grinder, and after that everything was good. It's a bit tricky if you try this, but I know now that I'll keep these and continue to use them.

Worked great

Doesnt fit, the bit is undersized and couldn't get a tube to fit the 3/4". The lead in is too steep and has a tendency to catch like a drill bit will and torques your wrist sideways which then bends the tube. Bad design! Luckily I had the sense to try it out on the old tubes before doing the new lines. I found one with a gradual rounded lead in so going to try that one. BTW, I wouldn't use these on higher pressure lines since it thins out the material (.045 start vs .030 finish), I think its OK for suction lines though just watch all of the copper shavings/flakes

Works as advertised. Had a set just like these for several months. Lost them on a job. Ordered a replacement set. Lot better than paying over $80.00 at a supply house.

Works well when fixing the plumbing. Good value

Love it saves losing time looking for couplings
