Ive read from various sources that harbor freight consumables such as cutoff wheels are known for exploding.

Is this true/ a common occurrence? I just bought myself a hercules flap disc and a five pack of baur cutoff wheels, both rated for 13,500 rpms and my grinder is rated for 11,500 im pretty sure (baur cordless brushless grinder)

If this is true, should I return them? Ive got them for DIY projects, so they wont be used every day, and they wont be used brutally.

I’ve been wanting to try this grinder for cutting metal only. But I would like to know if people liked this grinder.

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)

You guys can stop saying “unalived” - It’s gotten ridiculous.

Also premium cutoff wheels from Germany can blow up. Inspect your discs closely before use and never use damaged discs. Or you might get killed. But not unalived- I think that’s a zombie.
