M-jump 12 Pcs 2”X 1” X1/4” Flap Wheels Set –3 pcs Of Each 40 60 80 and 120 Grits Aluminum Oxide for Remove Rust and Weld Burr – 1/4 Shank Fits All Drills

Used them once and they fall apart

These are just what I needed. They last for quite a long time, and I haven’t had any break apart on me. I’m happy with the quality of these and will buy them again if needed for a future project.

A smaller shank would allow them to fit on my Dremel, too.

Poor quality item…. Not very durable

They are working great. Just what I ordered and needed

I intending these for my dremel since I was in need of a bigger sanding wheel.. I purchased these which has a much bigger shaft and will only fit a standard drill not a dremel.

These things wear out pretty fast & they shed like a dog so make sure you wear protective clothing.

Im using them to sand chip marks on glass. I sand them to make them smooth with 40 grit, and move to higher grit values for finishing. Silicon carbide is harder than glass so it works, and Im very satisfied with the results. Right now I dont have a vice or stationary drill press, so it is a little awkward to hold the glass in one hand and the drill in the other. But the bits do the job. These inexpensive grinder bits are made of many pieces of sandpaper attached in a fan shape around a shaft. An ingenious design, and inexpensive to build. Each bit will last about 20 minutes of intense use as the sandpaper wears down to the shaft. A real stone grinder bit would work better and last longer, but youd pay a lot more. Highly recommended as a low-cost grinder solution.

Self destruct real fast

Did not fit either of my 1/4 air die grinder I will have to use them in a drill. So not the plan
