> 3 dayReally smooth, nice grinder disc. Much better than those supplied for free with my grinder - which I used first then finished up with this one. I could have done the whole job with just this disk. It has a bit of flex to it which is nice to get into tough areas with high curvature. Definately recommend this disc to anyone.

> 3 dayI bought these to prep metal straps for a welding bend test, and they do what they are supposed to do and they seem like they last a little longer then the previous brands that i have purchased. The price on amazon seems to be a little lower than what they are at the stores in my area.

> 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).

> 3 dayBought this to sharpen my mower blades, based on a YouTube video I saw. These work so much better than a grinding wheel. Fast and easy sharpening, wish I had bought these years ago.

> 3 dayIve 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.
