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

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

Great deal and great product!!

For my money I always go with DeWalt. These remove material fast and last a long tim compared to other brands. Ive tried a lot of different makes and DeWalt seems to work the best so far. Their cutting/grinding stones are also great.

Welder must have. These are great,and work great for sharpies lawn mower blades as well.

I used this with a 4.5 Inch DeWalt Grinder. It installed easily and I didnt find that it slipped at all. I like the flaps because it allowed me to have a more smooth finish on the aluminum I was working with compared to a traditional grinding wheel. It doesnt bounce when you press it against the surface.

This cutting wheel may look thin but it cuts through soft to moderately hard metals better than expected. There didnt appear to be any noticeable wear or shedding after initial use. It appears the extra money was worth it.

These work great for my boat building project.

The flap disks wear out fast, and I mean FAST.

This thing is awesome. I have a few uneven pieces of wood flooring that Id been burning quite a bit of time slowly sanding down. I decided to try this out instead and in about 10 minutes Id managed to do what would have taken a few hours with the sander. That being said, be very careful since it removes a lot of material very quickly.
