Easy outs...
I can see two things wrong with that word
In all seriousness, they do work for some things, but the can sure create havoc too!
I do use them rarely, for me, I usually buy the ones from Gray or Snapon. I prefer the straight side ones as opposed to the screw style although I have a mix of both.
LH drill bits can work, but usually only when something is pretty loose to begin with. I like Dormer or Clarkson Osbourne for drill bits. Either right or left handed
That stuff is all good, but a welder and a washer and a nut is usually what I reach for.
