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

Great

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

Used on wook, plastic, Aluminum, Steel, Stainless steel, copper, & Brass. worked great on all of them. I like that you can stack them or just use one on a single spindle. PSA DONT run a high speeds! The heat buildup will melt them. Make sure you install on the spindle in the correct direction or it will fall apart fast. I found that 18kRPM is the max you want to run them and if you keep to that or slower they will last a very long time and do a better finish!

I was super skeptical once these arrived, as other had mentioned, there was no discernible difference between grit levels w the different colors, and they just look like plastic discs… but decided what do I have to lose, so gave it a try since I’m too cheap to shell out the cash for the 3M ones. I had this little copper washer I had soldered a couple jump rings into, and didn’t pickle it cause I was just playing around when I made it and didn’t have my pickle pot set up. Anyway, so it had a lot of fire scale and such on it and some excess solder. I started w 600 grit cause that’s what I pulled out first… and surprisingly, it actually was doing something! Tho it did far less on the back of the piece, so I decided to test out the 80 grit one… sure enough, it wasted NO time blasting away the solder and fire scale. Totally solves that question- there is DEFINITELY a difference w the different colors, as expected, 600 grit didn’t do much cause it needed a stronger grit. I then worked my way up from the bottom as your actually suppose to and now it’s looking real good and shiny! Definitely still learning about technique and best way to hold it and the dremel so the piece doesn’t fly out of my hand but so far so good, I’m very pleased! Great value, good affordable price, and none of the pieces even look worn at all! Thank you!

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.

I did a side by side comparison with the 3m radio disks on silver rings. The 3m products had greatly noticeable differences in performance. Recommend 3m

Worked surprisingly well had my doubts about rubber sanding discs. Only problem I had was telling the difference between grits. The color of discs didnt really match the color of them on the paper

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

Great selection of grits plus several mandrels, definitely a lot of bang for your bucks. Last quite a while, so may not have to replace real soon, but will definitely buy these again.

Easily shred and didn’t remove any gasket material
