AUSTOR 100 Pieces 1 inch Abrasive Wheel Buffing Polishing Wheel Set Polishing Wheel for Dremel Rotary Tool, 4 Grits

Shank is more like 3/32, which doesnt work with all Dremel chucks.

Great value for what I needed, but I have one gripe about them. It gives their grit numbers as: brown, 120; green, 180; red, 320; and black, 400. Its good that they told us that, because I would not have known any other way. Im using them on copper sheets and he difference between the various grits is not very obvious. In fact, the results all look virtually identical.

Worked well on my knife projects..

I love these for cleaning up aluminum automotive items. They work very well. Only problem I have with the them is that they wear out at a fast rate. But I like that better than them wearing out the items I’m using them on

These last a very long time (Im using a Dremel) exceeded my expectations

I used these wheels on a polishing job I was doing on ports on aluminum heads. Although the first few want okay (they dont last long at all), this particular one I didnt shove the shaft all the way into the chuck, but at least enough to grab the shaft of the bit quite a bit. Right on initial spin up, it bent from vibration/misaligned shaft. I never touched a single thing with it, just spun it up and it near vibrated the rotary tool right out of my hand. From then on I pushed the shaft of it all the way in and bottomed it out in the rotary tool and further usage in that way seemed to work. Know that the shaft of these bits are NOT hardened, and likely not expected from the price youre paying for them. Additionally, they last about 1 minute at most. On one head Ive managed to go through about 8 of these polishing bits. Its a good thing they give you a whole bunch of them because youll definitely chew through them!

As others have said, these are consumables. They might wear out a little bit faster than the expensive ones. But they are still a great value. I polished this tread plate, using two of each grit. There were a lot of holes and spots that would grab the buff and rip it up, if I wasnt careful. I polished mostly on the right edges, then spun it around and went again on the right edges. I started on a low speed, until I felt confident that I could stay off the left edges then sped the tool to medium. They wore out faster, but I was working faster too. Still a good value, and Ill continue to use these in the shop.

So I bought some more.Great for polishing knives.

Pros: 1. Love the quantity for the price 2. Quality of the polishing medium is decent Cons: 1. Quality Control is a bit spotty, had a few that were completely lopsided 2. Wish the inner piece the media was connected to was rounded, if you push down too hard you can really scratch what youre working on Photos are before, in progress, and after

China stuff. I use these abrasive wheels in my m12 rotary tool. I have not been able to find usa wheels.
