> 3 dayIve 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

> 3 dayI use this item for wood shaping and find its is not any better than the Ace Hardware version which is $1.50 less. So if you are trying to save a buck then reconsider your options. They both wear out within a half an hour of steady use. I would think it would be the same on metal for rust and paint removal.

> 3 dayIm 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.

> 3 dayUsed 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.

> 3 dayI 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!
