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

Good quality

The best polishing disc I ever used

I use these for sharpening my lawn mower blades. They dont take steel of they make them really sharp. Like always name brand last ten times longer than harbor freight

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.

Makes short work of fiberglass for epoxy repair. I bought 2 of these but the first disc has little wear and should last a very long time when grinding fiberglass.

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.

Bought this flap disc sanding wheel to specifically work with the Makita dust shield that I am using on a cheap Kawasaki 4 1/2 variable speed grinder that I got on Amazon. The dust shield attaches to my vacuum and really helps keep the dust down when Im grinding on fiberglass.

Excellent on fiberglass. Really cuts through so be careful. I found controlling it was easy after a little practice. Lasts long time.

Great item, works as directed. One thing I could not find on the disk is the expiration date. I thought all discs had them.

Im serious about blade care and these discs are the best way to hone a blade without taking off too much material. They last a long time and are easy to work with.
