    That was staged. If you look at his protective eyewear in the left pic not in the one where he is wearing them, you can see they used a cut off wheel to gouge it first, and then managed to insert the broken piece into the deepest portion of the blade to make it look like it was thrown off and lodged in there. So yea I wanted to see actual examples of discs. I've used dewalt, and personally I don't like them because the abrasive bond is too hard. Sure it lasts a long time, but it also takes a long time to make the cut with them. I prefer slightly more friable discs to have a balance of cut speed and longevity.
    This one doesn't look staged. There are a lot of WAY more graphic ones on Google Images.

    This one doesn't look staged, either. https://m.imgur.com/zOAyZxU

    If you're a pecker ( ), when you retract the blade and start again, the rim of the blade is going to have the opportunity to "clean up" the cut and shave off the side if the kerf where the blade was deflecting before. .

    Since the rim of the blade has more SFM, it aught to be more free cutting, plus it doesn't have the fiberglass strands slowing the cut down.

    Hope that makes sense. Post alcohol... Happy 4th!!!!!

    Its a matter of time with the ****ty little zip disk on electric grinders. I see guys attack everything with them like starved men and for me they are a last resort.

    Lol, I get it. But what I fail to get is how that would produce less deflection/different results than if you simply kept a steady, appropriate pressure on the blade for the whole 12 seconds. I guess I'll have to try it to see the difference.

    . Once I get to make some cuts with the Benchmark High Performance wheel, I’ll post how they perform.

    There's certainly a lot of dabbing going on, especially with stick welding thin gauge steel, lol.

    So then what is the duration of each dab that you use? Do you use 1 second each time? or more?

    Cut a notch out of the blade. It'll do the pecking for ya.

    This procedure prevents the blade from deflecting and causing the most common complaint of unsquare cuts.

    Blade life will also be greatly increased as it will run cooler and not be prone to glazing.

    Re: Evolution 14” Blade Mistake?

    I get good results using Makita wheels I get on Amazon.
    They last longer and seem to cut almost as fast as Dewalts.
    Never have done a scientific test on them though.

    I also use a 14" abrasive and a 12" carbide, both Makita's. They both have a purpose.
