I have a cheap mountain bike that I want to remove the cassette on.
It has 2 small dimples on the outside of the gear set 180 degrees apart.

You r correct ..without a picture I was shooting from the hip while trying to help.If you are talking about a bike with gears .. like an 18 speed or something , thats the wrong tool .. the tool you need looks similar , but nothing sticks up from the end.
it is a 12 point splined socket .. looks like a torx wrench , with twice as many teeth .. again similar to the other tool , with a hole going through for the axle
I think the 2 small dimples you are talking about are for the sprag clutch .. don,t try to take that apart
That's what I did with a wheel I needed the cassette off of. I needed some other things anyway, so I took it to the shop with me. It took 30 seconds, and they didn't charge a thing for it. She clamped a tool in the vice, dropped the wheel on it and gave it a spin as she walked past. I mentioned that I was going to work it out myself, I'm kind of handy that way, and I was told flat out "without the tool you'd never get it off."I'd go to the nearest bike shop. They have the right tools, and they may or may not charge you. You don't have to shop tools, and pay for something you'll probably only use once.
I find I get a lot of freebies from my bike shop, but I don't grumble about the bills when I get them, and they know its a motor bike.
