DEWALT DW8311 4-1/2-Inch by 5/8-Inch-11 36 Grit Zirconia Angle Grinder Flap Disc

This grinding wheel did an excellent job at grinding the welding areas 3 time faster and also smother then a standard grinding wheel.

Used to get clean finish on an edge. Works good.

Really 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.

it wears out fast but while it has the abrasive it takes out metal material fast

I 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.

They 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).

Bought 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.

Awesome grinding wheel did the job in quick time.quality Dewalt tools

Sands well

Ive 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.
