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

Is 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

Good quality

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.

Great grinding/sanding flap disk. Long wear.

It 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.

Perfect

I 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

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

Used 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.

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