I broke two Craftsman breaker bars, one the new free replacement, removing track bolts from a bulldozer. I was NOT using a’helper’. I borrowed an oldy, but beefier one from a friend, and completed the job. I haven’t bought a new Craftsman tool since.
When I broke the socket it was really my fault. I was trying to get a rusted nut off a seat mount in a Jeep. I had a 6 pt deep socket handy, and put the breaker bar on that. I’m reasonably certain if I had bothered to get a regular/short socket the sidewall would not have split. I ended up using an impact rated socket and impact wrench to jar it loose after a good soaking with penetrating oil. It is a poor craftsman who blames his tools - I don’t blame the socket, that was definitely mechanic error. ;-(
