Which Flap Disc is Best? Let's find out!

  • Published on: 11 March 2019
  • Always delivering 100% unsponsored content, I bought all the flap discs tested used in this video. The brands tested include: Harbor Freight Warrior, DeWalt, Makita, Walter Flex Steel, Diablo, and Norton Red Heat. A rusty piece of sheet metal was cut into 6 pieces. Each flap disc was provided 2 opportunities for a total of 3 minutes to remove as much rust as possible. The sheet metal was weighed before and after each timed event to figure out how much rust and metal was removed. 100% of the video ideas are from viewers. I greatly appreciate all the support that viewers provide, allowing the channel to deliver unsponsored, unbiased, content!

    I'm curious as to WHY the disks took so much less material off on the second tests? Do you think it was the pressure, or were the disks already that very much worn down from the first tests?

    HiCould you maybe do a test with these and run them for an extended period of time like 5/10 minutes. Thanks

    Can you do a video on 10 inch circular saw blades for a table saw? These blades vary greatly in price? Which one is best for the money?

    Another great test. The Norton was a bit of a let down. If you do another test in the future, can you consider adding Benchmark Abrasives to the test? Also, perhaps some ceramic discs?

    I’d buy the diablo for the price and work it does seems like the best value

    You are by far the best @ these comparison videos. No unnecessary banter that doesn't pertain to the video. Straight to business right out of the gate. Some of these people feel like they have to tell us what the weather is like where they are at, what they had for breakfast, etc. etc. blah blah blah. Who cares!? I dont. Well done sir!

    the diablo may be better overall because like you mentioned in another video, changing out parts saves time and gets more work done. however the makita seems to be the best value for work done. and as another person mentioned i appreciate that you test harbor freight items

    I don't use a lot of flap discs and only have experience with DeWalt and wonder if they have changed their product or are having a quality control issue. I had a disc that I used off and on for 2 full years, sharpening lawn mower blades or cleaning up welds. That one disc just kept going and going. When I finally needed a new one, I wanted another amazing quality DeWalt, but that sucker lasted less than 10 minutes before wearing out. I know it's only a sample size of 2, but the last one was so bad, I don't want to give them any more of my money.

    Thanks for spending money and time to make these videos for us. I really feel like you're the type of honest dude that can't be bought, and I appreciate your integrity in keeping things consistent in a real-world, "average Joe" setting.

    The first test compared to the second just shoes that the user should let the disc work, not his hand because adding pressure only destroys the disc faster and it applies to grinding and cutting discs as well.

    Drill speed was a little off next time if you need a jig set up you should try and pull the battery from the drill instead of taking the zip tie off but amazing video still

    Looked like Diablo to me. I would point out that the warrior wheels often have a coupon to get them for $1.50, and I've picked them up at $1 each before. Thanks for doing such excellent testing!

    Awesome! I was wandering about the quality of diablo flap discs, as they're the easiest and fastest to get ahold of in my town.

    Not to be rude, but you didn’t let the grinder ramp up then set it on the material

    A lot of people must of watched this because my local Harbor Freight was almost sold out of the Warrior 36 grit discs! I got 'em cheap for $1.49 each (limit 5) with the coupon.. Excellent comparison video Project Farm!

    Great test, when your the one buying the consumables Walter is a great choice, trim back the edge and leave 1/4 inch flapper exposed and you can blend steel again and again.

    Thanks for these videos. Very interesting stuff. How do you have time to do all these tests? Especially if you’re not sponsored or paid by any of these companies. This is awesome to know.

    How about comparing sandpaper. I have mixed feelings about HFT products, but one thing I will never recommend of theirs is their sandpaper. It doesn't seem to last even a minute before all the grit is gone.

    Great video as always. You put a lot of effort in and get excellent real world results.As far as this video goes, I would have liked to have seen the weights of the wheels after the second test. That would have given a good quantitative view of the amount of material lost.For a video idea, how about testing spray foams. Matt Risinger did a quick experiment on his channel showing the added structural value of spray foam. Perhaps you could test insulative capacity, adhesion, added rigidity, and usability.

    I think you videos are well put together and simple to follow. I would like to see a comparison of the flap disc to the hard wheel as far as cost to material removal rate. Which is the better use of time and money.
