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

use them alot

Maybe works nicely on wood, but even trying so sand off powder coat paint it doesnt last any longer than 90 seconds

Poor quality control 1/4 or .25 shank is just shy of 1/4 cant tighten the die grinder collet , Worthless!

These are really very useful for furniture work, edge smoothing, anything that you can picture them doing, they do well. Cant believe Im saying this but, YES, YOU DO NEED A DRILL with a standard chuck (not collet), and the faster it can go (rpm wise), the more effective your sanding will be. So lets talk about value: Youre getting a lot AND youre getting a good variety, different grits mean lots of options! After I bought this package for a very specific job, but my Dad immediately said hed buy some off me, because he would need them for a project hes undertaking. They are versatile and valuable and so convenient. Plenty of uses!

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.

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.

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

not many flaps and wear at an incredible speed. pay for nice ones, not these. they do get the job done while they last. reason for 2 stars.
