What is the name of the tool I need to remove my bottom bracket?
Sorry I'm fairly new here and can't post pictures yet. I have an 80s dawes Atlantis I'm trying to clean up. I bought myself a bicycle tool set, but it doesn't seem to have the tool I need.
I've removed the side that's round with 2 flat sides with an adjustable wrench, it's the other side that's giving me trouble. It's round and has 2 square holes which I believe the tool locks into, in order to twist it off.
Let me know if I need to provide any info Any help would be greatly appreciated.

Lockring spanner, then a pin tool for the adjustable cup.
If you're desperate, you can use a hammer & punch on the lock ring.

The drive side (with the gears) is called the fixed cup, which it sounds like you removed. That is usually the hard one to remove. The other side has a lock ring around the outside and then the adjustable cup which usually requires a pin type tool. Anyway, once you have ten posts, you can post pics and you'll get better advice on the tool you need. Just reply to this thread a couple of times. Here is Park Tool's array. The pin spanners are the ones I'm referring too but they are for round holes.

And a spanner tool, like this:

or there are tools with pins at a certain distance apart, but the spanner tool can adjust to various sizes.

I think you will need two tools. One for the lockring and then the spanner. If you make one more post, i think you can add pictures or links to pics and we can be sure. You the spanner to tighten to the right amount so the bearings are perfect, and the lockring to hold it in place. Unless you already have the lockring tool in your kit.

I actually prefer the cheaper pin tool. https://www.parktool.com/product/pin...er-green-spa-1
You need two tools to do this: a lockring tool to tighten or loosen the lockring, and a pin tool to hold or turn the adjustable cup. As you might guess by the name, the lockring locks down the adjustable cup when you tighten it.

If you're in SW CT, I have an extra lockring tool.

My toolkit came with a Lockring wrench, this is my 10th post so I'll add some photos to the main post in a few. I really appreciate the help.
I'm planning on completely disassembling the bike, cleaning it up and reassembling. Planning on taking my time and keeping it all original.

In the case of a BB adjustable cup, either one will do.

It looks like a pin tool is needed.
Despite the crappy, out of focus pic, it appears that cup is toast. Get a new one.
Be ready to chase the rusty threads with a tap or other device to clean up those threads before installing the new cup..

If parts of your existing bottom bracket need to be replaced, then it’s worth noting that a sealed cartridge bearing bottom bracket is probably cheaper, will last longer, and you already have the tool for it in your kit.

+1 this. While various pin spanners can work, the HCW-11 is made to fit the slots in that cup.

This is for the lock ring.
This is the pin tool for the adjustable cup.

Agree. This is ideal for the lockring, provided the ring has an even number of notches. If it's a three-notch ring, this tool won't fit.
The VAR #13 can work, but it's not ideal. I have both the VAR#13 and the Park HCW-11, and the HCW-11 is far better suited for the OP's type of adjustable cup. VAR did make a tool specifically for that type of cup (the #311), but IMO the Park tool still works better and is more affordable.

The pin tool only has to hold the adjustable cup in place while the lock ring is tightened. It sees a lot less torque than the lock ring.
The thing is, that adjustable cup looks badly mangled. It's almost to the point of drilling thru-holes or new holes or using a cup removal tool, a la Sheldon Brown.
