Great tools, I just wish there were slots provided in the case of the complete tool set , for these to be stored in. If not, then for the price there should have been a comparable blow-molded case for the extra dies. C'mon guys, a little common sense goes a long way here. Great tools, but you let us down on the storage aspects. Gotta protect my pricey tools! Got it?

I have the Mastercool 45 degree set and started working with AN fittings. AN fittings are 37 degree not 45 degree. Was pleased to find that all I needed was a die set. I tried out the 5/16 and 3/8 dies and they work great.

Man, I use the heck out of these things! I bought them as an add on to complete my Mastercool flare kit. These things are great quality, never slip on the hard line and work on Aluminum, CuNi, steel, and even really hard Stainless steel. Prettiest flares you've ever seen! Just remember to put the nut and sleeve on first... and face the sleeve in the right direction too.. Lol...

I bought these to flare 37 degree fittings in stainless tubing. Combined with the MasterCool universal hydraulic flaring fit, this kit made quality flares with ease every time.

Pretty good quality tool to use for doing Aircraft style flairs. only bitch i have is that they dont come in there own case. they are individually packaged and if you dont dedicate a spot for them in your tool box you could lose them. I would sweriously hope that at some point the design a blow moulded plastic case to store these fine tools.

Ordered wrong set and returned this one. I did however purchase a larger complete kit that works great. Would recomend Mastercool tools to anyone. They were great about accepting my return and even gave me the information for the set I needed. This is the only Flaring kit I would suggest if you want the job done right. Don't waist your money on any other setup!

Took awhile to get here but great tools from mastercool. I stripped the bubble (clamp) dies trying to do 3/8 stainless. It was .49 wall and way too thick. Should be able to handle .28 stainless. The does still work but leave marks on tubing now. Guess we’ll see how there warranty is.

The Mastercool kit is an addition to my existing Mastercool tools - brilliant tools to give a perfect finished result.The exceptional bit is that Amazon Prime facilitated getting this kit from Texas to Melbourne, Australia in four days and at a VERY good price!Amazon Prime has opened up a trustworthy international buying avenue for me I did not know existed.Well done.

The actual tool was and worked as expected, it did a great job flaring hydraulic lines to connect to jic fittings. The only down side is that there is no case for all the pieces and there is no place to put them in the master set. So a case included would be a great asset

You would think you are buying a top line tool and paying this much for it you would have a box to store it in. I have the full set with the press and everuthing but there is no room to put these in it and the item doesnt come with a molded case or anythig. Non even available to pirchace separatley.These are not cheap so you want to have a storage made for them.Good job mastertools ðŸ™
