> 24 hourIs not the same threads as one bought previously- so if you dont use it immediately are your just out of luck? please take a look at my previous Dewalt (and other) 5/8-11 thread purchases- there is something wrong with this disc

> 24 hourI 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.

> 24 hourIt works, nothing too special. I find the cheaper Home Depot discs just as effective. I am using it to take off old paint on a steel toolbox.

> 24 hourI sculpt with metal, mainly found steel, and use flap discs in the finishing process often on very rough surfaces. These discs are workhorses, work rapidly and produce fine finishes

> 24 hourUsed a few of these flat wheels to refurbish a rusty mower. Worked slick and so much better then a flexible abrasive disc. Anyone with a 4-1/2 grinder should have a few of these to go with the other discs.

> 24 hourThis grinding wheel did an excellent job at grinding the welding areas 3 time faster and also smother then a standard grinding wheel.
