Excellent budget friendly for the weekend warrior
I think it’s important to realize that this is $40 and not $150+. I have used a flaring tool exactly twice now and I will be surprised if I use it more than two more times in my lifetime. It’s very infrequent so I didn’t mind getting a cheaper tool. The reason I bought it instead of bumming one off of someone I know is because the cutter still works on copper water lines too so I’m sure to find more use out of it. The reason I got this is I did my own mini split install in my shop. The line set it came with was 15’ and I only needed about 6’. So I cut the two lines and flared them with this tool. The thing I thought was awesome was the attachment I’m holding in the picturing. If you are too aggressive with your cutter you can accidentally fold in the edge of the line making it hard to do a clean flare. This is used first to spread the opening back out to normal diameter so when you use the actual flaring end it will come out smooth and seat nicely on its mating surface. It’s a compact lit that does something like 1/8” - 5/8” lines and it worked out perfectly for my needs and if you just wanna have your own and know you’ll only use it a handful of times then I’d definitely recommend trying this set out.

Great kit works well after many uses
I use it frequently, did a whole car with it without issues. I'd buy this kit again.

Saved me time and money worked for me
Needed to flare some break lines and had no experience. Watched some videos, picked up this flaring tool kit. and 30 minutes later had new flared break lines. Did a few practice runs to get the feel for the toll and after some adjustments to my technique, worked great for me. My error was not tightening enough and having a clean square cut. Those two errors on my part caused the flare to be improper and not clean. Cut nice square ends, properly seat the tubing and tighten down properly and the results where exactly what they should be. Breaklines are in, no leaks, and most importantly, my pickup stops when I hit the brakes.

Everything you want for a bargain price! Flares are better than the 60440
Nearly a perfect tool! It’s not perfect but close. For the price it’s incredible! I’ve always been a fan of the 60440 flaring tool. I absolutely feel this tool makes better flares. I may even add some photos, it really is excellent. Never mind the bad reviews some people don’t know how to use the tool and even posted photos of the tube going the wrong way though the clamp! Lol, then called the makers of the product idiotic. I kid you not look at the photos above!! It makes excellent flares and swages perfectly! Functionality: Flares and swages, almost exactly like the 60440, probably better.

Do not buy this tool if you are flaring NiCopp tubing
I bought this tool based on the 62% of reviewers considered it a decent tool and gave it a 5 star rating. It might be fine for copper or aluminum but it is not capable of making double flares on 5/16 NiCopp tubing. To be honest, I don't think any of the Chinese made, clamping bar type flaring tools sold on Amazon are worth your money. Here are my complaints; 1. Wing nuts suck. I suppose they use them so folks won't over-tighten the bar clamp. I used a wrench to get the wing nuts a little tighter but not too tight. The bar clamp holds the tubing securely. It did not slip through the clamp while I was performing the first step of a double flare. 2. There are no sizes stamped on the bar clamp but I suppose you'd have to be an idiot not to use the right holes. 3. When the bar clamp is tightened the two halves do not meet squarely. The gap between the two halves was greater at the bottom and this produces a crooked flare. 4. I put a drop of oil on the tip of the anvil but the tubing scratched it. You would think this would be a hardened part. The Ares flaring tool I bought at the same time did not show any gouges or scratches. 5. I didn't use the tubing cutter because it is probably junk too. 6. I didn't use their 5/16 double flare button because some of the reviews said they were cheaply made. I used the button from my 1970s Craftsman flaring tool which has always given me good service. If you insist on buying this tool, make sure you use oil on the threads and tip of the anvil tool. Use just a touch of grease on the double flaring button. File the end of your tubing square and chamfer the inside and outside diameter. This tool will still make a crappy flare though.

Broke after 4 flares
One of the lockdown bolts on the die stripped on the fourth flare. The tightening bar is small diameter & short, impossible to over tighten. I was able to find a bolt in my shop that matched the threads and allow me to finish the flare I was making. But I ordered a higher quality tool to finish the job. I don’t flare a lot of fittings, was hoping that I could get by with this tool. Maybe the threads in the tool I got were just a quality control failure, the rest of the tool seems OK. But it still cost me in the end.
