Eastwood tubing flare tool. Very rarely am I impressed by a tool. This thing never gives a bad flare. Use it with steel, nicad, and stainless. Perfect every time.
Just don't go king kong on the tool. I broke mine, cracked the back off where it holds the blocks. I think I can fix it by milling the back and attaching a steel plate to replace the part that holds the blocks in place.
