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!

Works well on fired ceramic clay.
These grinding bits work well on fired ceramic clay, but less in glaze/glass.

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 for fine work when removing grout
I am using these to help in grout removal from between floor tiles. The size of the tip is good for this work but buy lots as they wear out quickly. I bought 20 - 2 packs and I hope it is enough.

Always Dremel Brand
Dremel tools and accessories are always a cut above the bargain priced alternatives. They consistently run faster and truer. I've yet to get a bent shift on a Dremel branded bit. I've never had a Dremel grinder catastrophic fail when using within the specified aameters. Or outside the parameters, for that matter. They nearly always last longer and remain usable down to the nib. For jobs when I have a lot of material to move, I'll do the gross removal with cheap Chinese bits but for any fine, delicate, precision work, only genuine Dremel. And these silicon carbide bits are no exception. I'll be working with glass with these. They came out of the package running smooth and true. No burrs or abnormalities or voids. And that's key to getting good results with glass. Minimal vibration with the bit remaining in contact with the work surface. No jumping around causing cracks and clamshells. Genuine Dremel bits are expensive, no two ways around it, especially at the retail stores and Lowe's is on another planet. But you get what you pay for. And to keep prices in check, I look on Amazon, frequently, for deals. They're out there. You just have to be patient. If you see a good deal, jump on it! Even if you don't need a particular bit right them, if you use your Dremel often, you'll probably find a use for it. There's nothing worse than needing a tool right now that you have to wait for or use the almost right bit. Take it from me, stick with Dremel. Still made in the U.S.A.!

Good bit
I use these to file my cuticles if I’m being honest so I guess it’s pretty functional because that is not the intended use. Works well just go easy so you don’t take too many layers off! The size is perfect for my need. They are pretty durable for my needs anyway! I feel the value is good as this comes as a set of 2.
