> 3 dayI like these but the life span of good grinding seems to be short for the price paid. The benefit though is the ability to grind without grinding hard flat points into the material. With practice you can follow the natural contour of the metal you are grinding. Use these when you want to shape or clean off the surface; used the solid grinding wheels when you need to grind down to get the final shape before using these disks.

> 3 dayI havent used other flap discs so I cant compare but I was pretty happy using it. It didnt last as long as I wanted which is why I gave it 4 stars instead of 5. I did order another one I liked it so much. I plan on trying other ones and comparing- after I do I might change this review. I used it to smooth out my terrible welding skills and it did great. I tried it on truck bedliner though and it heated it up too much. It turned it into wet tar and made it harder to take off. But I didnt get it for that anyways. Works great on metal.

09-06-2025This 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.

> 3 dayFor 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.

> 3 dayWorks very well, does not last long though so order plenty. I dont know how I ever did car restoration before without these. Removes paint quickly, removes rust pretty well too. Very fast paint stripping. Also really good for finishing body seam sealer or panel adhesive where you need to level and pretty it up.
