Query: Life saver tool for me

I had a square head drain plug (10mm square) in my transmission that had been very badly damaged (rounded etc.) by someone else in previous attempts to remove it with a vice grip pliers etc. I had the proper square socket to fit the plug but could only get it on part way to to all of the damage to the plug. I rounded it off even worse. I was willing to sacrifice this tool just to make an attempt at removing the plug as the alternative was to drill the center of the plug and use a screw extractor -- not something I was looking forward to doing.The plug was in so tight, I had to use a 1/2" to 3/8" adapter to use a ratchet long enough to give me the leverage I needed.I not only removed the damaged drain plug, the socket was in perfect condition afterward (not what I expected at all). What a life saver tool!!!
