HANSUM Brake Line Flaring Tool Kit - Professional Swaging HVAC Pipe Expander with Eccentric Cone for Brass & Copper Tube Repair (45 Degree Flaring Tool) - Perfect for Automotive Brake Lines & Refrigeration System Maintenance

This tool creates mirror smooth mating surface on the flare. The amount of strength that is needed to form the flare is reasonable. This tool appears to be built sturdily and to high tolerances. Case and point, the tool grabs the pipe tightly without deforming the pipe.This is a knock-off of other tools that a lot of pros seem to be using. A lot of pros may also use this tool. The important point here is that the design works very well!For the non-professionals who are planning to use this tool, ignore the reviews that report that the cone is crooked. The cone is designed to be eccentric (off-center). By mounting the cone this way, only a small portion of the surface of the cone actually touches the tubing as the cone is being pressed into the tubing. This drastically increases the pressure that is applied at the contact point. Secondly, there is a clutch mechanism built into the tool so that when forming the flare it will stop pushing into the tubing once the forming cone has gone far enough.The package comes with both metric dies and SAE dies. I was pleased to see that the package also contains a nice deburring tool and a very high quality pipe cutter.
