So I was trying to remove my bottom bracket since its almost 20-30 ish yrs old and not running well, but it just seems stuck. My guess is that it is rusted in.
Tried WD-40 and rust remover along with a long lever, but then my removal tool from cyclus broke.
I'm not sure if the material is tool weak, the rust bond of the BB is too strong or if me not fixating the tool with a clamp, thus the tool being not properly in the threads and pulling too hard off center was is the issue (which I'd do differently now that I know).
Would you guys buy another tool? Is there even a better brand than cyclus? Or will this BB stay on forever?
I'd be happy for any input. Thanks so much in advance!

Are you certain that you’re unscrewing it in the proper direction?
You buy a new one. Preferably not made from Chinesium.
The Park tool version of this tool is inexpensive, and strong. Bolt it to the BB via the crank bolt, and this will never happen again.
Get the park tool.
When removing take the tool and place it in a bench vice. Then use the frame as leverage to remove the BB. You will be able to remove that no problem with the right tool and method.
Good luck.
While you’re waiting for new tool to arrive trying loading it up with some WD40 or liquid wrench. Set it and forget it. I dig the makeshift breaker bar lol. Maybe might have to consider impact drill?
Chinese alumi bb tool will always lose versus an old (stronger, way stronger) steel bb cup. I’d soak them cups with Kroll penetrating oil, and get a better name brand tool. Doesn’t have to be Park which is insanely overpriced, but at least get a steel one
The good news is that the tool was worth more than the bike….
Maybe not enough good tool left here, but I have managed to grind down similar tools to leave just good splines. And, as many have stated…bolt the thing to the bb next time with the bolt that holds the arm on or a similar spare one. Screwed up one of these tools many years ago…just once then learned to bolt it on. May need some large washers to help facilitate this trick. Some bb tools have big holes in them that the bolt head can go through.
A 50/50 mixture of diesel and used car transmission fluid is one of the best penetrating oils you can use.
Get a new socket and use a 1/2″ drive iimpact
Kroil. Let it soak in there for a couple days.
i like the park tool (or is it the pedro?) version that is machined for a 1/2″ breaker bar. you will never be doing whatever the fuck you are doing in that picture again.
Pb blaster near the threads.
Heat it up. Leave it in the sun, or if you don’t mind repainting…. Torch.
Aluminum tool. You need a steel one. Park tools are solid.
Impact gun.
Nex time fix it to the bb with crankset bolt, so it won’t slip.
