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

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.

These dont last too long, however they do a stellar job at what I purchased them to do (polishing metal). I would argue they last a little less time than the name brand units, but at 1/8th the cost you cant do much better! Great variety pack, although I do wish they sold larger packs of the individual grits.

Lower cost option than purchasing the Dremel product. Great selection, great price, bulk quantity. I did not notice any difference in how long the discs lasted compared to the Dremel products. I use a lot of these for firearm polishing and find this the best option to purchase.

No differences.

These things are great. I find the key to making them last is very light pressure with high rpm. Ive used two different ones so far with a couple hours use on each polishing gm cylinder heads. Great buy!

Works very well! Highly Recommend! Best Price on-line

With a lot of rotary tool going on in my shop right now these did the trick perfectly. I use them pretty agressively hence the durability stars, but its my fault.

Great for cleaning and polishing parts during restoration work. A bargain for the price. They work well.

Works As described, could be made more durable but for the price you can order 3x the amount as a dremel branded and itll last just as long if not longer and it kind of lets you refresh your bit. And in my opinion that allows for better quality sanding, because it allows you to take time to view your work. Some may or like it like this, but I rather the bit weak out if your doing something wrong as apposed to your standing or polishing to go too long and not notice a mistake. Also if you use it correctly it last just as long as a branded type *its when you use it against the edges the wrong way it wont last but half the amount of time. So experience is key and these allow you to gain that experience with feedback by the bit wearing out quicker than normal with less cost. Even the branded dremel will wear out 2x faster if your incorrectly using it, keep that in kind as well.

No differences.
