For all the complaints about not being true to 1/2. Cant speak to that, but a makita electric die grinder has no trouble chucking them. They stand out stiffly at rpm... so yeah, you need pressure to use them.

use them alot

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.

Good value. Should be long lasting.

Cleaning rust off metal fence

I had seen these before and I assume there must be some use for it, however, my experience is that this product is not functional. I used it to sand down a bike frame. the blades are relatively short and stiff. You need to apply a good amount of pressure. Otherwise only the outer edges will touch your work surface. Even with pressure, the contact with your work surface is relatively limited and you are effectively only using 10-20% of the sanding surface. The additional pressure makes the material wear out quickly. The blades tend to become frayed on the edges and too smooth to be effective. Possibly I am doing it wrong but I believe in order to be functional the individual blades would need to be a tad more flexible and maybe a tad longer.

They are working great. Just what I ordered and needed

Used these on some rust spots on my 60 TV tower. Much easier and faster than hand sanding.

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