42pcs 1 Inch Radial Bristle Disc Kit with 3mm Shank for Rotary Tools,Detail Abrasive Wheel for Jewelry Wood Metal Polishing, Bristle Wheel with Grit 80-2500

They fell apart extreamly easy. No I didnt run them over 15,000 rpms either

Incredible breakthrough...great for hard to reach places

They work great

Stacking them2 or 3 tall seems to make quick work of pain on aluminum engine parts. Pat attention to the direction of tool rotation and the whiskers on the bits

They work great. I just wish the colors were all different. There are a few that are very similar colors (but different grit) so it’s a little difficult to differentiate.

Ive never used this type before. If memory serves, this type of abrasive bit had just been released by 3M when life detoured me away from jewelry making years ago. While I cant give you an opinion on how these compare to the 3M variety, I can say that Im impressed and wish these had been available when I started my journey in silversmithing. Wow, these are versatile and handy. Not sure about durability, but I used various grits last night for hours on Argentium Silver (more silver content and harder than traditional Sterling silver) and none of them are showing much in the signs of wear and tear. Will be purchasing again when needed. Many people are griping about the amount of mandrels that comes with these, as in, while you get many, its not quite enough to have one of each grit available at the same time. Super easy work around folks, you can buy multi packs of mandrels on Amazon fairly cheap. Im planning on doing that anyway, because they are stackable, and it would be handy to not only have one of each grit mounted and ready to work, but also a few ready to go stacked grits for covering larger areas faster.

Polished my older silver to a mirror shine. Im excited to be able to learn how to use the disks without investing so much.

Dont apply to much pressure when sanding with these. They shred and fall apart on metal

I sent them back because I thought they were for a dremel. But I got them fast there were a lot of them and the looked good and they refunded (processed) my money the next day

I’m a silversmith and use these daily
