Hi Jim,
they are good drills and fit the Dremel collets very easily, but they are incredibly fragile and break off easily.

Yes, Brian! They are really good quality (while I inspected them), and yes, I expect them to be really fragile...but the size....0.1mm. I have no idea such size exists. I am not even sure if I ever will use this size

Jim only use smallest sizes in a drill stand.I managed to put copper nails in a grating using 0.18mm drill and 0.15 wire.Any vibration will kill the drill,I used MF70 mill to do this.

Kind Regards
