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

If used properly, these are a great alternative to 3M for Metalsmithing.

mandrels were stripped out.

This is just so bad. The discs break on the first try. Horrible quality.

I was very impressed. A plastic disc? Ha! I used them to polish a stone! Not alot of shaping with them but they definitely are worth the money. I havent wore any out yet. Con: 7 grits and only 6 mandrels. But if your like me, there were a couple of spares in the box!

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.

Do not mount them in the direction as thier package shows or the picture on website. This is reverse of how it should be! I have added a picture of the proper direction. Also they should be stacked two high. Be nice if there was one more mandrel.

Love them on wood not so great on metal

Really amazing value. They work really well. And amazing price for how much they provide. I’m some regards I like the 3m ones better. Those seem more flexible, and have varying sizes. But these actually seem to deburr and clean scratches more easily which is nice.

I just started using these for polishing sea shells, so I cant attest to how long theyll last. I have flap sanders that only go up to 400 grit, I like that these go the additional steps, 600,1000, and 2500. They gave a pretty good shine to the shells that I wasnt able to get in a tumbler yet. I also like how thin they are that I can get into tough to reach spaces.
