These discs don't mess around. I got a pack of 80grit 4.5" discs and they really make beveling and prepping steel a very easy job. Couple it with a powerful grinder that doesn't mind getting a hot supper, like a metabo, and you've got a great tool to work with. It seems like these wear longer than contemporary cheap flapper discs you can find other places. They hold together, wear evenly, bite hard when you need them to remove material, and leave a great finish when you apply light pressure. I think these last longer than the jumbo flap discs we've had at the shop, even though they are thinner like a regular flap disc.I'm still on the fence about the price, but it will take me quite a bit of fab and repair work to burn through the 10pk of these discs, so there is certainly value there.Good buy and if you have a quality grinder that's smooth to run on its own, you will enjoy working with these higher quality discs.

I have dabbled around with different abrasive disc... From the solid wheels, to another "Katzco" brand flap disc.. & this is by far the preferred abrasive material removal disc..Basically I liked this one the most.It cost more. But it knocks it in the head if you want to take metal down FAST. I was removing an old iron pipe, at least part of it, doing a little minor home renovation. I didn't want to dig up concrete, and all that, I just wanted to get it down to floor level. The pipe was sealed up, and of no structural consequence or anything else. So using a portable bandsaw, I cut so much off.. and had about 1/4 inch worth of material sticking up out of the concrete floor.. I tried my katzco flap on it, a 60 grit on it.. and it worked until the disc wore out really quick.. and I switched over to one of these, and it just.. took it down to size & didn't wear out. That was impressive.No buyer remorse. The value they bring is worth the money.

These FlexSteel line of flap wheels are, hands down, an amazing product. Many manufacturers claim longevity with their brands; however, this is the first time I have genuinely noticed a flap wheel lasting longer. They are trimable and this feature also gives you a new edge to start working with. I have worked in many fab shops before owning my own, and see many wasted flap wheels once the edge gets worn out and that's totally losing money. Not only do these flap wheels last longer compared to other brands, the feature gives you additional life. This product also has special technology that allows the abrasives to self-sharpen when the wheel is being used under less pressure than that of which would be used for heavy material removal. And this means saving money. When you own a small business like I do, every penny counts! Whether you're considering for rust removal or heavy material removal, these FlexSteel flap wheels are a home run! No hesitation in referring this product. It is all we currently buy and use!

They seem to work just fine. They seem to wear well so far. They are a little thicker in the center but still fit on my grinder ok.

I could kick myself for 10 years for not trying these sooner.Trust me when I say, as if this writing, all other flap discs are worthless. Yes, you are going to pay about twice as much for these as the cheap stuff from places like Benchmark but these last 10x longer or more. The bigger deal is how well they work in addition to the life. These things just won’t die.When they do die, you just cut some off and it’s started all over.There’s no way I will ever buy discount or store bought flap discs anymore.

These disc are better than all the brands I've tried. That being said the cost does not make them a good choice. They would have to last 3 times longer than the other brands they do not. Maybe if they cost 25 it would be worth it at almost 50 not cost effective.

I have used several brands of flap disks and these shine above them all. One of these provides more production than a 10 pack of some brands. The Flex Steel are perfect for my 8 amp Bosch grinder. It's the first disk that continues to bite into the work after it's been well worn. I like the 60 grit for all purpose weld grinding, rust removal, and light beveling.

Top of the line flap disc. Once you try these you won't go back to conventional ones. Like the slight give of the plastic backing and that you can mill off the backing with a chisel for a renewed edge. Last twice as long if not more than the conventional hard backed rigid ones. Love em!
