Pull the endcap (the black cylinder) out. Don’t forget to put it back after you reinstall cassette.

That’s looks like a “freewheel” tool instead of one for a cassette. They look really similar but are different dimensions and not compatible with each other

End cap has wrench flats, likely can’t pull it off. Have you tried giving the tool a light love tap with a soft mallet to get it set better?

I’ve never seen an end cap on a bike wheel in my life

Wrong tool. That’s for freewheels.

That’s not a lockring tool, that’s a freewheel tool. Lockring tools are like 3 mm deep (eight of an inch), not 20mm.

Many here are saying it’s a freewheel tool. That might not be the case. There are 3 very similar cassette tools that all look the same.
One, the normal Shimano HG tool.
One is the Campagnolo cassette/bb tool which look identical but does not fit.
And then there is a freewheel tool that looks just like a cassette lockring tool. But it’s slightly different.
Any of these could be the issue without seeing more pictures of the tool.

Here’s a little insider tip. Shimano only makes tools where they feel the available options are inferior. Buy the Shimano tool – problem solved

Does it have a pin that goes into the axle hole? Looks like the wrong tool to me.
You can put a skewer through the hub and use the lever to clamp the tool on. Might hold tight enough.

To the folks saying this is the wrong tool – stop. This tool is fine. It is not a freewheel tool. Its engaged in the photos and should be able to easily remove the lockring as its shown. The splines don’t need to go all the way in. It may be bottoming on the locknut but it still works if you hold the tool in place. I have a tool just like it and it can take lockings on and off all day. Believe it or not, I also have a freewheel tool. It is indeed different.
OP, if you’re still concerned, go to a bike shop and they should be able to clear it up for you.
This post makes me feel good that real bike mechanics are still nowhere close to being replaced by the internet..

Thats an end cap. I don’t know what make your hub is but you can remove it or if you can’t you’ll have to get the proper tool. A normal cassette tool won’t work.

It’s not that deep anyway. And or pebble.
Because your endcap is stopping it.
Looks like a freewheel tool. You need a cassette tool with short stubby splines.

Even if this were a cassette lockring tool (it’s not), it might not fit over the thru-axle. I’ve got a 30 year old Park cassette that doesn’t work on either side of my modern 12×142 Shimano hub. I got [this](https://www.performancebike.com/unior-1670.9-4-cassette-lockring-tool-w-12mm-guide-pin-black-625615/p1335345) Unior tool that is deep and pilots and it works great on cassettes and rotors.
