Greater than one weekIve used several of these (60 grit and others) for grinding welds, deburring, chamfering and similar tasks. These are pretty good - they cut quickly, leave a decent finish, and last a while. That being said, I prefer the Walter 15W456 - they cut a bit more quickly and you can trim them when theyre used up to get a bit more life out of them.

> 3 daySecond time buying these and would buy again. A great option. Lasts way longer than regular sanding pads so worth the extra money.

> 3 dayI havent used other flap discs so I cant compare but I was pretty happy using it. It didnt last as long as I wanted which is why I gave it 4 stars instead of 5. I did order another one I liked it so much. I plan on trying other ones and comparing- after I do I might change this review. I used it to smooth out my terrible welding skills and it did great. I tried it on truck bedliner though and it heated it up too much. It turned it into wet tar and made it harder to take off. But I didnt get it for that anyways. Works great on metal.

> 3 dayThey grind down material real fast (and make a LOT of dust). They hold up pretty good as well. I just used one one two different flooring jobs with particleboard subflooring. One was a 9 to 10 inch wide, and 1/4 inch high ring around a toilet flange., it ground down in minutes. The second was a spot where a customers dog would wet the floor under a desk. It was circular about twenty inches in diameter and 3/8 inches high in places. The same disk leveled it out in minutes as well. The disk looked like it had more life in it, but I pitched it anyway (it stank like dog urine).
