This is one of my favorite grinding and finishing disc ever!! Cleans up welds good for preparing any material that I’ve tried it on so far. Metal wood fiberglass plastic, removing old glues etc..

Not good. Grit coming off.
I used this disc for probably 90 seconds to remove the paint and sharpen one brand new mower blade. To be specific, I ground away from the sharp edge, removed the initial layer of new paint and a minimal amount of metal, and barely used any pressure at all. The leading edge is now missing quite a bit of grit (see pic). I like the Diablo saw blades and thought these would be quality, but these flap discs are a complete let down.

    This product has the right angle for re-sharpening the (3) blades on a turn on a dime lawn tractor. It works Great on an angle grinder and jig for the re surfacing .

    I used the disk to remove rust from a piece of old steel grate, the kind that utility trailer ramps are made of to use for my smoker grill. When I was finished the grate looked shiny and new. Great product

    Worked Great!
    I used this flap wheel to remove thinset from an oak floor after discovering that a wire brush on a drill was not going to get it done. This sure did! For what its worth, one wheel did the job for me, but it was pretty well worn out by the end of the job. If the area was any larger I would have needed two. The area that I was working on was about 3 ft. x 4 ft. and was pretty well covered in thinset.

    Exceptional Longevity
    The Diablo Steel Demon Flap Disc is substantial and has lasted far longer than expected. Although it is developed for use on steel, it was found to be absolutely essential for working with wood too. Obviously, top quality materials went into the design of the product and the construction of it adds to its efficiency and longevity. Effective and long lasting...what more could you ask for? Sold. I love it.

    GOOD IDEA!
    I was really looking forward to the arrival of this "innovative" new grinder/polisher disc. My husband renovates antique tractors so there is always plenty of metal grinding and polishing. This has been the job of two separate discs in the past. The disc arrived. It looks very well made and incorporates both grinding and polishing discs. I didn't pay any attention to the size of the arbor...the hole that fits on the grinder. This arbor is 7/8" and the grinder needs a 3/4". I'm hoping to find an adapter. I would recommend this product. I can't see any reason why it wouldn't work as advertized. I have has other Diablo products and have never been disappointed.
