I finally had a chance to use these stones on a real project: grinding some details into a piece of 440-C hardened stainless steel. They worked great! Used several of the different shapes and sizes, and they all performed well. In general, they worked much better than the stones that I got with my Dremel.

Had a few that were glued on warped and could not be used but overall I was happy with the stones and how long they lasted while grinding.

I was surprised how well the abrasive tips hold up. I am working with steel. They cut very good and hold up. I had to wear one down to a point on some hardened steel and the tip was even cutting that. Im impressed :)

A really nice set of stones for a good price. They seem to be high quality and they get the job done!

These are trash. Donรขโฌโขt last 15 seconds, not worth taking a chance.After the first disintegrated, I thought maybe itรขโฌโขs a one off. Nope, every one Iรขโฌโขve tried either came unglued, broke, or completely came apart at 20k rpm on my dremel. Useless.

I use these for grinding semi-precious stones to create rough shapes before doing final shapes and polishing. To be honest, my 100 grit sandpaper heads actually are more aggressive. But these do work and the various shapes come in handy.

Great set, with plenty of size variations to pick from to do the right job.
