Do ensure you get the genuine 3M ones. Different manufacturers use different colours. I find the light green are usually my last stage. But yes you are correct, you need to work up through a couple of grades first. personally I love the yellow ones. great for removing tarnish and cleaning a joint before and after soldering.

If I may, at the risk of being "that guy," bristle discs and Scotchbrite buffs are totally different animals. Scotchbrite buffs are essentially made from the same material as 3M's abrasive pads for household cleaning, automotive paint prep, oxidation removal, etc. A highly porous material. The bristle discs are based on 3M's Trizact abrasive, one of the reasons they cost so much more than Scotchbrite buffs. An essence, a series of triangles that break into smaller triangles as the product is used. Enjoyed the video. I just love the bristle discs.

Thank you! I'm getting some of these to polish seeds for jewelry making. I've been making my own discs with regulard sandpaper, but I think these radial discs would do a way better job. I have just one question: how long do they last?
Impossible to say, it depends on what you're doing and how heavy you are with them. I ve found that the coarser grits wear out quicker and the finer ones seem to last longer. I can also say that the genuine branded 3M discs last way longer than other such as the evebnflex versions. hope this helps. Dave
Celtic Dreams I’m mostly only going to sand and polish some natural seeds (sea beans). I usually start with the 80 grit and work my way up to 2000. I’m mostly worried that the discs are only going to last 3 or 4 times.
If the item is lightly scratched, then polishing is the way to go.. Se my video here on polishing a mens bracelet...Dave ua-cam.com/video/Iv6NNClZdNU/v-deo.htmlsi=1pRIm73sJgZZeoR7
Thank you for this! I use these myself and love them for clean up and pre polishing in my own work. May I ask why you recommend not mixing older discs with new ones? I admit to mixing them to stretch out their use. But if there is reason not to I'd love to know :)
+Jay Cuneo Hello. Firstly the discs reduce in diameter when they wear down, hence new discs will be bigger in diameter. They will also be sharper and cut more. Hence a combination of the two will result in a uneven finish. Also, older discs may be dirty or contaminated, so adding the newer discs will be a waste of time as the finish is only as good as the worst disc. I too use them way past their best - I just wish they where cheaper. Thanks for watching. Dave.
Thank you Dave, makes sense. I'll change my methods. Just got in new mandrels so I'll can hold on to a set of old ones when I don't need as much grit and have fresh sets on standby for when I do
The finer grits last longer such as the green. The harsher grits like the yellow wear out quicker. I wouldn't say they are a replacement for traditional mops and polishes. They are an 'additional' method when your in a hurry, or just require a small touch up. Dave
For removing solder you really want something firmer. That way you can remove solder but not the metal around it. I use thick abrasive rubber wheels with square edges (Eveflex discs), or knife edge wheels for tight areas. Or course the skill is to avoid using excess solder in the first place, and eliminate the need for cleanup afterwards. But when it comes to final finishing of the area, then these 3M radial discs are far superior and longer lasting than the eveflex version. Hope this helps. Dave
Impossible question to answer. it depends on how hard you push, which discs you use, the speed and of course how long it takes you to polish each ring. but what I can say is that the 3M radial discs are "very" long lasting, especially compared to the silicone ones such as the eveflex. Dave
Celtic Dreams thanks for the answer! As someone who is new to jewelry polishing, even an order of magnitude would be helpful. Is it closer to 1, 10, or 100 uses before needing replacement?
A lot of work sanding a door and you'd go through a lot of discs. I'd recommend a "flapwheel". More aggressive and will last longer. See link. Dave www.dremel.com/en_US/accessories-and-attachments/-/subcategory/accessory/find-by-tool/27343/rotary/27381
Hi Dave, Which discs would you recommend to remove lot of scratches & polishing a stainless steel watch case that has also semi precious stones set in it?
+Les 24 As with any scratch removal, you'd start with a coarse one to remove the scratches and then work up to finer grits to get a polish. The brown is the coarsest, so Id probably start with that one. Then move to a yellow, I use this a lot on silver, but the steel may need the brown one first. Blue will start to get a smooth slightly satin finish and pale green to finish. As with everything, it will take time, especially in steel and be careful around the stones, especially with the brown disc. see the link below there is an image of the whole range which I made for Eternal (under the main pic) www.eternaltools.com/polishing-abrasives/3m-radial-bristle-polishing-discs Depending on how deep the scratches are, you may prefer to polish them out using a cotton mop and some polishing compound www.eternaltools.com/polishing-abrasives/mounted-calico-wheel I can highly recommend Menzerna IP grey polish as used in many of my videos, but I only know of Sutton tools that supply it in the UK www.suttontools.co.uk/menzerna-p164-polishing-compound.html Hope this all helps you out. just shout or email me direct if you need any further advice.

I''m not an engineer, but I don't see why not. They are designed for polishing soft metals. The finer ones, such as the green or pink, would have more of a cleaning effect. whereas the coarser grits would have more of a polishing effect. Dave
+Dexterko They do seem to last very well. As they are "impregnated" rather than coated, they never loose their abrasive quality. What happens is they get smaller as they wear down. I have a set of yellow ones which I've had for a few months now and they are pretty much worn down now (used several times a week). They may seem a little pricey, but they do last. In contrast some polishing points and rubber tips can wear down in seconds on one task.
I remember when these first came out, a salesman for a tool company came into our store and gave some free samples to us bench guys. The first time I tried one all the "bristles' tore off and went flying around the room. I'll stick with regular brushes with tripoli and rouge, thank you.
I've never had that problem. Forgive me for saying the obvious, but did you have them the right way round?. I have tried a few others though like the Eve twist ones and they are no where near as good as the genuine 3M ones. So I would definitely encourage you to try them again, but ensure you get genuine 3M ones - they 'are' good.. Kind regards, Dave.
I can only repeat that I love them, and likewise several other jewellery friends do to. However , In the spirit of an honest review. I will include your thoughts. Thanks for Sharing. Dave.
Desmond Murphy Sorry but you're a perfect example of someone who's been doing something for a long time and because of that you think you can't improve it. People use these all the time and they're excellent, and you jumped into the conclusion that they're crap because you used it ONCE, and most probably in a totally incorrect way.
+Carlos Vanquish ... I've only used them with silver and gold.When polishing glass watch fronts you usually need a strong abrasive such as diamond and there are special creams for doing this. Vice versa plastic is usually polished with a soft mop and special compound.....see the links. Dave. www.eternaltools.com/polywatch-scratch-remover www.eternaltools.com/diamond-polishing-paste
Copper is toxic? Ive never heard that before. The pipes in my house are copper and many people buy copper bracelets for arthritis. But certainly dust in any form isn't a good thing, so a dust mask is always recommended when sanding and polishing. Thanks for watching. Dave
