60 Pack Abrasive Wheels, Rocaris 1“ Abrasive Buffing Polishing Wheels Burr for Rotary Tools-1/8 Shank，Polishing bits

Bought these to port and polish my v6 cylinder heads. This packed lasted long enough to polish all 6 combustion chambers and exhaust ports. 10/10 purchase for the price. Resulted in a mirror finish

I use these to fine sand my rocks that I carve. So they dont last long, but they do the job they need to do and they work better as a sanding bit going around then most sanding discs do from the top only and flat.

I've taken up airbrushing lately and I also own and operate a few 3D printers as hobbies. While I tend to focus on functional components, I will 3D print decorative figures and statues to use up aging filament.I realized I can give such figures and statues new life by airbrushing and painting them, so I've been practicing with failed prints. I've found out the hard way that thicker layer heights on prints, while they may take less time to print, give rough appearances that really show when painted.So, I've been trying out different tools to smooth prints, and these are one item I tried. As stated in the review title, these aren't working the way I expected, but they're still handy and helpful.I expected these rounded wheels to somewhat flex and mold themselves to surfaces as they sand. I thought this would be helpful for small nooks and crannies in prints, such as eye sockets in a large animal print. Sadly, that's not the case. The wheels do conform ever so slightly to the surface you're sanding, but nowhere near enough to reach into nooks and crannies.However, I find these are MUCH easier to smoothly and consistently sand 3D prints as compared to drums, discs, spiral sandpaper bits, and even burrs. So for that reason, I'm keeping these in my rotary tool arsenal. I will attest with others that these wheels do disintegrate as they're used, so in addition to dust from sanding, you will have fine fragments and dust from these wheels as they wear down.So if you're having trouble with other rotary tool sanding attachments as described above, these are definitely worth a try.

Fits my drimmel just fine and they get the job done, however they do where out pretty quick, good think there are so many for this price, cant beat it!

These are very handy and the perfect size for cleaning the wheels on my S scale trains when used with my variable speed Dremel tool.I especially like that each one comes with its own shaft -ready to use right out of the box.The large quantity, and economical price is a great bonus.I’m sure I will find many other uses for these besides just my trains as they come in a variety of coarseness.

These may have been cheap, but you get what you pay for. They immediately began dissintegrating with use and I ended up having to change them out multiple times while buffing. Plus, they shed colored fibers as they dissintegrate, leaving a mess.

Work great

I'll start with the "bad". When I got my bits, they came inside an Amazon box... inside an Amazon box. There was really no "formal" packaging & the bits weren't separated, just all tossed into the cardboard box. Not a problem except when it came time to sort them. The Gray & Black wheels are significantly different as far as grit/abrasiveness goes, however they look pretty much identical in color so good luck differentiating em... Take that as you will.As far as performance, they seem fine, I've never used "name brand" wheels of this type so I can't compare the 2, however 1 wheel seemed to last for 1 project; very light touch up to remove plastic "flashing" on a 700 stock I modified. I feel it wore out pretty quickly for what I used it for, but then again, you get a bunch & they're inexpensive.
