Can’t remove the right side bottom bracket.. the tool I got kidna sucks. What can I do to loosen it? WD-40? Should I buy the parktool bb removal tool? Will my bb get destroyed if I keep trying myself? Should I go to the mechanic at this point? I managed only to get one side off..

If it’s 44mm I’d get the Pedro’s socket, because it’s steel.
drive-side: righty-loosey (reverse threaded)
The right side is reverse threaded
get a better penetrant.. not WD-40. not sure what brands are available in your country.. i used permatex when soaking my cup&cone BB(seized together after 3 years). still need to borrow a breaker bar though.
my replacement BB(similar to yours) came with aluminum wrenches. i used a regular wrench to add leverage when i scrapped that bike after damaging the frame. i did add grease when installing it.
i gave the BB and crank to a friend. 1 year ago.
Are you rotating it back towards to rear wheel to loosen it?
I’d be concerned about continuing to use that BB tool with the rounded out teeth. That tooling interface is already kinda precarious, and that damage isn’t going to help with confident tool engagement. Might be worth getting a fresh one.
Are you sure you’re turning the cup the correct way? Assuming it’s English threaded, the drive side/right side cup is reverse threaded, and as such loosens toward the front of the bike/righty loosey/clockwise.
If you’re turning the correct way, I’d get some penetrating oil, drip some into the threads, and walk away for a while so it can do its thing. If you get the oil in the bearings it will wreck them, so be careful if you’re planning on reusing the BB, but it will help loosen any seized threads.
If that STILL doesn’t work, I’d take it into a shop and see what they can do.
Best of luck!!
Yea, not to be another one of those guys but… can we see which way the lever is flipped on your wrench?

Do you have a pipe or something to extend the length? Get more leverage.
Right side/drive side is a left-hand-thread… Just you know… make shure.
WD40 isnt a bad idea. By the looks of it youll destroy that tool (which indeed sucks) before the bb.
The cheap Shimano bb tool has always worked for me (TL-FC32 I think). Pipe wrench and new bb is also an option.
Parktool is nice but expensive.
All of the options above are considerably cheaper than a mechanic (at least where I live) on the other hand supporting your local bike store is cool.
i know a fair few people have said you might be doing it the wrong way, me included. but i just noticed the gash marks going clockwise. lay the bike flat, put the tool on, attach the wrench, slide a big metal tube or bar over the wrench to give yourself extra leverage. keep your hand on the BB tool to keep it located and slowly put all your weight onto the bar clockwise. some of the teeth are damaged but a solid, constant load should eak this puppy out
I’d get a steel tool just like you have and a breaker bar and when you install the new BB make sure to use some anti-seize on the threads.
If you’re having trouble still with a jammed BB, try pointing a hair dryer at it for a minute or so.
Thanks for the comments I appreciate it. I am turning the right side clockwise, but still it either takes Hulk force to remove it or my bb tool is a bit shitty.
I think the latter.. I’m already damaging the bb so I’m not sure I wanna continue ðŸ˜
If you have a mounted vise, and the frame can clear the area, tighten the bb in, and then gently turn the frame…
I’ve had to put a pipe over the handle of the wrench and the extra leverage usually does it for me
Get a steel socket (not alloy like the one in your pic) and put it in a bench vice facing up. Assuming the rest of the frame is stripped of parts, place the frame over the tool so that gravity is working with you, and use the frame itself as the lever. A second person helps a lot here.
Penetrating fluid, soak it, a lot, a few times. Then if no dice take it to a local bike shop.
