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

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.

Good product

These fell apart within a few seconds when used for aluminum, not just one grade but all of the grades. Dont waste your money on these.

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

Works fine but they dont last but about a minute before disintegrating.

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.

They fall apart fast, but they are so cheap that it doesnt matter. The more expensive ones last 10% longer but are 3x the price.

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

These work perfectly for cylinder head porting on aluminum heads. Ive been porting for many years and wish I had found these long ago.

I ordered 5 packages and I received 4, having problems getting this resolved.
