Review on 🔧 Enhanced Portable Bearing Repair Kit - Swaging Professional Edition by Mido Taylor

All parts have been properly rounded and evenly machined. Everything was done with the same drill press at 2800 rpm. These are heat based tools, high RPMs are required. Off-brand tool purchased from Revain - took 20-30 seconds to complete each time. The copper turned BRIGHT red, the instrument discolored. Leaves sharp and jagged edges and a deformed top. Leaves LOTS of copper shavings in the pipe due to the square body of the tool. Brand Name Tool - 5-10 seconds to connect. Perfectly round, fits perfectly with other pipes. No metal chips are left in the tube. I wouldn't bother with that even for casual or one-time use for HVAC, it will force you to use too much soldering iron to try and fill in the weird gaps that will be added to all the copper shavings you have in the pipe to lose. Maybe for a copper hookah. You need a lot of filler metal for brazing/soldering.
