Great Tool
Yes, Yes, Yes, finally a tool that works. I ordered two other double flaring tools and neither held the 1/16 inch tubing in place. This one works, very nice double flare on all the lines that needed one. Easy to use. in vise or hand held.

Nothing to think about. Buy the tool if you need to double flare 3/16th lines.
This thing is Amazing. I dont see how anyone who can follow simple instructions cant flare a brake line. Believe me if you can't make this tool work you should not be working on something as important as brakes. It is so easy. Cut and deburr tubing slide on your fitting the thead side down. Then take the tool thread the given alinement stop bolt in the end and slide the tubing in firm against. Then tighten the 2 10m bolts to secure it to the line. Then take outo the alinement tool then take the die and thread it in the side marked operation 1 first and tighten until it bottoms out. Dont forget to greese it first. The unbolt the die and greese the other end snug it down. Then back it out and back off your 10 mm bolts and it's good to go with a perfect flare. I was doing a complete system so I was doing several flares. I used my 20 volt brushless 1/4 in dewalt impact driver to tighten the 10 mm bolts and to drive the 3/4 8n bolt. Not sure if that's recommended but it sure made things go fast. You just got to be smart and not get crazy and I had no problems. Out of a entire under the floor brake job I only had to redo 2 flares. Once because the tube slipped when tighten it down and wasn't in the tool enough. I mean it was a flare but not very pretty. Then the other was the typical thing we all do. I forgot to put my threaded fitting on. The line first and had to cut off a perfect flare. My only down side to the tool is the handle. I know they wanted it to be able to remove it so it could be used in a vice. The down side is it just screws in hand tight and it always backs off and the tool wants to spin in hand if its loose. Other than that this thing out the box will make flares like some of 400 dollar sets. For the price and quality job it does I am okay with it. Way better than the old kind that you clamp the tube between 2 bars and then slide the flaring tool on the arms. Then you had to use a little button thing and press again for a double and they never make the double ones well. They do Ok at a single flare but who is going to do brakes with a single flare? Also I would like to state that I ran a copper nickle line. I can not speak to how well it would do on steel lines. But I doubt it would have to much trouble. Also I seen someone say he had to modify the alignment bolt so it screwed in 1mm closer or something. I never had that issue. Maybe he had one that they missed on quality control who knows. But overall don't think twice if you need to do brake lines it's amazing. I got to run a 5/16 tube for fuel I was going to use the old style flare tool since it is very little pressure any way with a carb set up. But I might buy one like this in the bigger size. We will see. I hope this helps someone so they can decide to make a solid purchase of a great tool. You can look at my reviews I have done several and they are not all good and I am not paid. I call them like I see them I just think this is the most bang for the buck for this type of tool.

Compact and effective
Easy to use. I had no problem making double flares using stainless steel line biding that stainless steel is harder to work with than copper or galvanized steel. Only draw back, it would be great if it had a smaller block to hold line to make shorter flare to bends.

Great tool
This is the best flair tool I've ever used. It makes a perfect flair first try every time. Works better than the hydraulic tools costing a few hundred bucks.

Tricky to double flare Nickle Copper brake lines!
This Capri Tools CP21110-316 Double Flaring Tool works great when making SAE double inverted flares on Steel lines but has an issue double flaring NiCopp (Nickle-10%/Copper-90%) 3/16" tubing/lines. I spent 6ft of NiCopp trying to perfect the flares with this tool doing 3" straps at a time before I cut my actual Jeep lines. The instructions work for Steel but don't work for NiCopp. I'm not the only one with this problem. What I noticed is that putting the line flush against the stopper bolt like instructions state makes the punch die twist the flare causing deformities that look like it's lopsided on one part of the side of flare. That's not acceptable in my book. Now it is soft NiCopp and may crush into place if tightened several times in the hose/ABS fitting/connection. But I'd rather make an acceptable flare that's uniform all the way around. And I did, after days of trial and error I found backing off the NiCopp tubing about 2-2.5mm from the stopper bolt then tightening down until there was great resistance on 10mm bolts, created almost perfect flares that are more than acceptable in your vehicle. I included a picture with the gap, it's about the same size as the line marker on see through hold on the tool.. so make sure its gapped if you are using this tool for Nickle Copper brake lines to make SAE Double Flares. One picture shows the perfect Flare, and the video shows the wonky flares I got while following instructions. Tips: • Use punch grease and don't just use a tiny bit on tip of die, get a little on whole mating area. • I tightened until it bottomed and was flush with Tool on both dies. I do hear some Tools require stopping once there is strong resistance when using NiCopp. • clean off dies before every use so you don't get dirty and obstructions between punch and line. • you must debur and chamfer line before Flaring. Use a countersink to debur the inside rim of tubing of all sharp points. Then use a fine file to flaten the end of all lips and sharp points them chamfer outside, you are only trying to remove sharp areas, make it smooth. • when you chamfer & file and debur your line you want to hold it down so gravity keeps shavings out of the line. You don't want shaving in high pressure lines that have 1000-2000psi Great tool, well made definitely purchase, you can get high quality flares of nearly all kinds of alloys. This problem is not restricted to this Capri Tools CP21110-316 Double Flaring Tool, it also happens on the Titan 51535, the Lisle and the Eastwood hand Flaring tools, they are all built the same exact way. It's all to do with the type of metal and its strength and possibly a slight difference in quality control. There are overwhelming good reviews of this Tool of all brands on Amazon, Ebay, Home Depot, Lowes, and other sites. I'm giving it 4 stars because it is not working following directions but it is a great tool.

The best handheld for tight spaces
If you find yourself constantly doing brake lines while still mounted to the car this is hands down the best tool to have. Shoutout to Kevin at Junkyard Digs for showing me this, it is a game changer for doing brake lines. Super easy setup, just tighten 3 bolts and youre done. Very well made tool, will hold up for a long time. Makes doing brake lines actually fun for once!

Best flaring tool I've used
Out if all the budget friendly flaring tools I have tried, I've never had one work as good as this one doing anything more than a single flare. This worked seamlessly. Put 1 bubble flare on off vehicle, worked good. The other end of the brake line is had to do while under the vehicle at a wierd angle. This still worked great and gave me a perfect bubble flare on that end as well

High quality tool - Buy this instead of the cheap knock offs
Bought this to repair rusted brake lines for my daughters boyfriends car. It really is worth the extra ten bucks or so to buy this one. The tooling quality is high, plus in my case I was able to repair the line in place (under the car) which was possible do to the size and design of this tool.

Perfect doubles flares every time
I had also bought one of the cheap vice-held sets that wasn't fit for purpose. This, however, is a good quality item that produces perfect double flares every time. The grip holds the pipe firmly without damage and without needing to overtighten the nuts. The best thing is that all the critical settings, e.g. how far the pipe protrudes, how much the formers should be tightened down, are all controlled so no guesswork is required. Also, the formers are kept square to the pipe producing nice symmetrical flares - this is the big weakness with the cheap sets. Great tool and well worth the money.

Smart tool
Better than other pipe flange we have a lot easer to use

Worth Every Penny
I have had this tool for a while now and wanted to use it for a few different times to give and accurate assessment...well here's my story....For decades I have been using those cheap flare tools. The ones that come in the cheap plastic box (usually red in color) The ones where you clamp the tube in the hole between two die halves using the undersized wing nuts that you could never get tight enough to keep the tube from slipping. I've had to redo more flares with those cheap tools than i care to even remember. They rarely came out perfect, they were always slanted or not quite flared enough...but i do remember all of the skinned knuckles!! Just to get one good flare could take multiple tries and the better part of and hour. Well i had to redo the entire braking system on my old jeep. I was just dreading this job. So I got on everyones favorite video site and looked or a different way. There I found a video reviewing this Capri brake flare tool. I was impressed with the video so I ordered one. When it arrived i followed the instructions did a couple of practice flares. No kidding, they all turned out first try. I never knew it could be this easy. Once I got the hang of it i could do a flare in a minute or two rather than the normal 1/2 hour or so. I was able to unscrew the handle and place the body of the tool in my vise which made flaring even easier...it is near impossible to to use the cheap tool with a vise as the vise jaws are in the way and you also have to remove the tool from the vice and undo the wingnuts every time you started a new flare...With the Capri you can leave it in the vise until you are finished all of your flares!! ...and...you can use a wrench or a ratchet to create the flare rather than twisting with your bar hands on those other near useless cheap tools. also, this Capri tool appears to be made of hardened steel as my vise did not mar it up much even after being clamped tightly....Spend the extra money on this quality tool and forget the other ones even exist. You can thank me later...would recommend 5 stars.
