That usually requires a lot of leverage like a long breaker bar.

It’s a left handed thread. You’re tightening it. Reverse direction and pray it’s not completely dicked up.

Hope you’re going clockwise or you just tightened the shit out of that.

Just check you are unscrewing. Left handed thread 😀
If you have been tightening it. You are gonna have a bad time.

Yup, that’s a left handed thread, so opens clockwise

Get one of those wrenches with a reaaaaally long handle and don’t be afraid to put some force in it

Fire or, weld something to the BB and hit it with a hammer. (sorry my english haha i could explain better in spanish haha)

Aluminum oxide is the worst. Especially if you have a steel/aluminum interface because then it’s possible you have a galvanized bond meaning it’s hopeless. Do you have to remove it?
You can try soaking in PB Blaster or another penetrating fluid for a few days, but good chance it won’t help. Soaking Ammonia might help though since it’ll lightly dissolve it aluminum oxide. You can try heating/freezing especially if the BB is steel since it’ll respond differently than the AL which might break the seal.

You can see by the way tool twists in his hands he is tightening it for sure

jesus christ dude, didn’t even to think to look it up before either using a powertool OR recording a video to ask for help.
I predict a rough future in the bike mechanic field for you unless you can learn how to google shit

I’ve found those AC powered impact wrenches to be generally underwhelming and not nearly as powerful as they seem. The best way to get this off would be with a very long breaker bar.
Also, as other posters have mentioned, the BB is reverse threaded on the drive side of the bike. So, lefty tighty righty loosey.

You need leverage, like a lot of it.

Using power tools on a bike is a “Never ever fucking ever”.

Basically do the opposite of what you are currently doing.

Put the bb tool in a vice, then holding the bike above the vice, rotate the bike to unscrew the bb.
The bike frame is large and will give you leverage.

I had a similar issue a while back, tried the impact driver which didn’t work. What finally worked was a bit of heat gun and a long bar (I got one that was almost a metre long) with the BB socket

Impact with non impact sockets and tools is a recipe for smashing things. Don’t do that.

Last time I had to deal with a tricky bottom bracket, I ran a QR axle through the bottom bracket and removal tool to hold them together, then used a really long wrench for leverage.
