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

I purchased this to sharpen my mower blade. It worked exactly as intended. Only took a few passes to produce a clean / sharp blade. Cant ask for anything better. Seems to be well made and the price was reasonable. Highly recommend for sharpening mower blades. Use PPE and safety guidelines for angle grinders!

Hard to criticize this product. Love not using wrenches to change wheels out and is long lasting

I guess I was looking more for a solid disc not one that looks like a disc with pieces of sand paper attached to it. For a grinder it may be alright but I was a little disappointed with my purchase.

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

Ive tried to sace money using less expensive brands but I end up have to change out the disc more often which at the end I spend more money. This dewalt disc is definitely worth the money

I 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.

I 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.

Love these wheels that just screw on. You dont have to mess with taking the locking nut on and off of grinder. Used these pads for years and always loved em. They last surprisingly long. Wont ever get another brand of flap discs. DeWalt cutoff wheels on the other hand, leave a lot to be desired.

I was suggested this product for sharpening lawn mower blades, it fell apart before I even got done sharpening one blade. Might work alright for a more gentle application that doesn’t include shaving metal. Back to the trusty grinding wheel.

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.
