40 Pcs 1/8” Shank Flap Wheels Set, 10pcs of Each 60/80/120/240 Grits Abrasive Sandpaper Flap Sanding Wheel Grinding Head Rotary Tool for Grinding ...

As SEVERAL others have mentioned and taken photos of - which I now see (wasn't smart) - these are USELESS. I purchased these for the different (10pcs of Each 60/80/120/240) Grits Total junk. ALL of them are mostly glued together (the flaps so no way to move a flap and see if any grit marking is on it); all of them seem to be the SAME grit - and only the '80' grit is marked. TEN of these are marked. The other 30 are all probably the same extreme LOW QUALITY of 80 grit. JUNK, JUNK, JUNK!! Do NOT buy. These are going back. Not bothering to take some photos - in the reviews - I see plenty of photos of exactly what I got, Total not useful junk.

Suggest purchasing in this bulk capacity as they wear out quickly; they will get your job done if jobs are small. Used to remove rust and sharpen outdoor cutting blades. Cheers!

Only the 80 grit was labeled.

These work okay on wood, but as soon as the hit steel there is tons of fiber and cheap paper everywhere!!! The dont take much off while disintegrating themselves. Dont buy these if your going to depend on them at work, but for projects around the house they may be okay. I had to polish several hydraulic cylinder barrels from rust in the ends of the barrels and it went at a rate of 4-5 flap wheels per barrel. They are only 4 bode cylinders and all shouldnt have worn out ONE good flap wheel. Buy with discretion

The media could not be loaded. So I received these wheel sanders for my rotary tool as a free item to review, I had big expectations that were beyond the fisical capacity of the materials. Let me explain... First, I like how they're built, they look as they won't come apart while using them, and they have the grit written in the top. When I installed them in my rottary tool, I set the top speed and turned the thing on, my mistake, of course they will be out of balance, there is no way you can balance sheets of sandpaper to spin a t 10000rpm, everything started to shake, so turned the speed down and it was controllable. I tried it first with wood, and noticed that these wear pretty fast, just went 2 inches on the wood and you can see in the pictures how much material the sandpaper lost. So, in conclusion, these are helpful, they are really good, but for small projects like sanding rusty bolts, where a metal brush wont't brighten them up, or finish a metal weld, or corner, they are well made, and won't come apart, but you will use a lot of them. Hope this info was helpful to you!!
