Haven't tried them yet but I'm sure they will work just fine. I'm happy with them.

I hate giving a bad review especially when this seems to be the new norm. Not sure how this even got started that a 3mm mounted stone will work in a 1/8 die grinder. on some the collet may close tight enough to hold the stone however even if it does it is spinning off center making precision work impossible. It is so frustrating trying to find an economical 1/8" or .125 mounted stone. Most sellers if you read the listing will state they are really 3mm or made for a dremel tool. Unfortunate that some like this seller does not. These make matters worse because they are on the small side of the tolerance they are really .115 diameter or .003 smaller than 3mm.So in short if you have a precision .125 die grinder for doing precision work look elsewhere.

I used one grinding stone for about 30 seconds, it would not hold in my dremel with a new collet insert. After a couple tries, I finally measured the shaft diameter. It was about .010 inch undersized compared to a standard dremel tool shaft. The grinding stone shaft is too small to safely hold in a dremel. I'm returning the whole box. What a waste of time.
