Harbor Freight Cut-Off Wheels? | BobIsTheOilGuy

I’m not entirely sure this is the right sub for this, and I am pretty sure this is my own stupidity, but I’m having trouble getting grinder wheels to work on my grinder. I just got the cordless Hercules grinder and it works great with the wheel it comes with and any other “grinding” (1/4”) wheels. But any cutoff wheels that are thinner than that won’t attach properly. The nut that screws on to secure it won’t tighten far enough. I feel like this is a user error, because there’s no way they only take one wheel thickness. And all of the wheels are 4.5 or 5 inches as the grinder suggests, with a 7/8” arbor. Do I need a spacer or something? And I have tried the nut flipped, as it protrudes a little more on one side. I’ve also tried them on a corded craftsman grinder with the same results. Thank you for the help, my apologies if this is a simple fix that I’m over looking. (First picture is the included one that works fine, other two are the ones in question)
