WORKPRO 20-Pack Flap Discs, 4-1/2-inch, Arbor Size 7/8-inch, T29 Zirconia Abrasive Grinding Wheel and Flap Sanding Disc, Includes 40/60/80/120 Grits

This set includes 40, 60, 80, and 120 grits, all of which are useful. The packaging was appealing because they were all shrink wrapped, which helped to keep them safe during shipping. The grit on the flap discs themselves is nice and uniform, and they perform just as well. br>br> They live up to their four-star rating. On my angle grinder, they are 5 inches in diameter and rotate without causing any noticeable vibrations. These appear to last the same amount of time as other brands I've tried. The ones that have worn all the way down haven't had any missing flaps, and the discs have used up all of the paper just fine; the only criticism I have is that the paper description on the other side of the disc is best pulled off rather than letting it come off on its own. This is a shame because that is the most straightforward way to determine their grit level. It would be preferable if the grit size was printed directly on the disc. br>br>I would definitely buy a set of these again for the price.

I'll update this review if I have a serious problem with one or if one breaks. br>I haven't had much opportunity to use these; I've only used one disc a few times because I've been using my other 7" grinder lately. I've noticed that the wear is a little faster than my black and yellows, though it still has plenty of life left. It's just showing signs of wear a little faster than my black and yellows, which is to be expected. br>I'd give it a solid 3 for overall construction quality. I'd give it an 8 out of 5, or a 4 on a scale of 1 to 5. I mostly have expensive flappers to compare to, and you can definitely see and feel the difference, with the weight, thickness, density, glue, and other factors all being of average quality, which was to be expected. br>However, for the price difference compared to my other options, these appear to be a better overall value, assuming nothing goes wrong. If I don't update this with something like "junk" or "blew up on me," it means I recommend them and have most likely purchased more.

They resemble my name-brand discs in appearance. The 60-inch version has about 5 less flaps. grit wheel in comparison to the 60-grit wheel Dewalt wheel with fine grit When I use them, however, I can't tell the difference. The discs are sold in ten-packs, each with five 60-minute discs. grit, 3 grit 80-grit grit grit grit two 120-grit grits grit. As a result, you're getting 20 grinding discs for less than the cost of four name-brand discs. This is a great deal!.

The discs have been impregnated, i. e. a 40-degree grinding surface 80 grit lasted for less than a day. After 2 minutes of light use, it is completely ineffective at removing anything from the metal surface. The sparks flew at first, and the surface preparation went as planned. After a one-hour break, There were no sparks, no metal, and no removal in 2 minutes. The abrasive surface was worn and had little or no abrasive left, only fabric, so it wasn't due to debris from scaling and rust loading the wheel surface. A higher-quality disc, such as one made of silicon carbide, will give you more bang for your buck. It was a good lesson.

After a week of light use with carbon steel, the first one is still going strong. I've used it to remove mill scale and grind bevels. Paint would be able to stick to the surface. The downside for me is that I prefer type 27 to type 29, so that is a drawback. With the type 27, it's much easier to keep everything in order.

These sanding disk packs may offer the best value for money. I'd give it five stars for that. However, there were no 40 grit discs in my set, despite the fact that I had anticipated receiving ten. Instead, I got around 10 60 grit discs and 6 80 grit discs because I need to grind down a lot of material. 60 grit is nearly as aggressive as 40 grit. However, it will take a little more time. As a result, I'm giving it four out of five stars.

First and foremost, let's start with the basics. You can't go wrong with a buck a piece. They're just as durable as the Home Depot's Diablo ones. Diablo cards cost $7 each. They outlasted my Lehigh Valley discs, which cost $4 each, by a long shot. The price is acceptable to me. br>br>I wish I had the option of picking my grit. br>br>The fiberglass is a little flimsy; I smacked the metal against the table and ripped off four flaps, which threw the disc off balance. That was not what I was expecting. I'm not complaining, though, because they're only a buck each.

Overall, this is a great deal, but as other reviewers have pointed out, it does not include all of the grits mentioned. I received only 40-percent of the votes. 60 grit. It would have been nice if they had included one of the finer grits mentioned for finishing work where a less aggressive grit is preferred, but given the price, I'll still give it a fair rating.
