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

Im writing this review because I tried the alternatives. I wanted to strip the paint off my deck (I didnt paint it), and started with the deck stripper chemical (which did well). For the parts coated too thickly with paint for the stripper to work, I tried various wheels that attached to my drill (ineffective), the random orbit sander (blew through discs and wouldnt fit everywhere), then the angle-grinder sanding discs with a separate quick loading adapter (flat discs were too hard to control). This 120-grit disc took off just the right amount of material (a bit more aggressive than 60 grit on a random orbit sander) without a lot of scratching. It lasted through everything I wanted to sand: especially all the vertical surfaces under the deck and stairs, and between balusters. Really useful and efficient.

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.

Bought this to sharpen my mower blades, based on a YouTube video I saw. These work so much better than a grinding wheel. Fast and easy sharpening, wish I had bought these years ago.

This disc powers through lawn mower blade sharpening. Makes quick work with quality results.

They grind down material real fast (and make a LOT of dust). They hold up pretty good as well. I just used one one two different flooring jobs with particleboard subflooring. One was a 9 to 10 inch wide, and 1/4 inch high ring around a toilet flange., it ground down in minutes. The second was a spot where a customers dog would wet the floor under a desk. It was circular about twenty inches in diameter and 3/8 inches high in places. The same disk leveled it out in minutes as well. The disk looked like it had more life in it, but I pitched it anyway (it stank like dog urine).

These are then light weight discs with a fiber core. The paper abrasive flaps don’t seem to last as long. The price was good and the seller great.

Ive been using the disc to sharpen mower blades. Works great. Sharpened four 21 blades and still looks new. I suspect it will last me a long time with my limited use.

Used to get clean finish on an edge. Works good.

Great product. Just used once, but attached to my Dewalt grinder and sharpened a lawnmower blade in about two minutes razor sharp. Sure beats grinding away with my old dull file for 30 minutes. Will be ordering more of these for other uses. Seems like it will last along time too.

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!
