Perfect for small places
I’ve owned several Dremels and love that all of the bits fit perfectly and have different uses. It’s such a reliable tool; I currently own three. One for hobby use, one for pet nails & beaks and a third for garden/home repairs. They never disappoint! These bits handle grinding in small places with ease.

Great grinder
Used on clay flower pots. Works as intended.

They work as intended.
I’ve used these to wear down grout. They wear out kind of fast, but I’m using them a little harder than probably intended. They seem fine.

DREMEL IS BETTER
Hold up longer then the Chinese off brands. Two for $4 is a great deal for two tools that either save you money or make you money!

Excellent Strength & Durability
Already used them the day they arrived. 2 are in the package for a great value for the price. They are so easy to use and the size is exactly what I needed to drill holes in pottery that I'm turning into planters. Very durable and strong. Great Quality. Thank you for offering these and saving me a trip to the big box hardware store that sells Dremel accessories.

Looks Nice, but Does Very Little
It's a very nice-looking product, is well-balanced and sheer. Unfortunately, even at 15,000 rpm, it hardly grinds anything. The stone is extremely smooth and has no substantial grit to it; for example, at 15,000 rpm, I could only slowly grind away at the end of my thumbnail, and only after I put real pressure on it. My advice, look elsewhere; this is much more of a polishing bit than a grinding stone. Go for a diamond-coated bit: you'll never be disappointed with one of those! For the price I paid for these bits, I guess I can't complain though...

Good quality and work very well!
These Dremel grinding bits are just what I needed for my gunsmithing on my pistols. They are made well and work just great. No complaints at all. They're small enough to get into tight spaces and they have just enough grit to get the job done without overdoing it. I'm very happy with these bits and will buy more when needed!

Decent
Worked okay on aluminum wheels, they are small and you will probably need multiple.
