    The DeWalt wheel is my go to grinding wheel for most jobs. The Warrior is faster but its dirty. I produces too much grinder wheel dust that's both in the air and all around the work area. I tried Norton wheels a while ago, likely an older version than you tested here but they were slow to cut but they lasted a long time. The problem was a wheel that's slow to cut slows down the job. The DeWalt has always been the happy medium. If I'm just working on junk outside, and don't care about clean up, I do keep a few packs of Warrior wheels on hand but only for emergencies or if I'm trying to save my good wheels for something more important. The Warrior wheels do better on softer metals and for use in places where the wheel may catch or break easy. If I'm going to damage a wheel prematurely, I'd rather tear up a $.99 wheel then a $5 wheel. The DeWalt wheels seem to be the same as the older Black and Decker Industrial wheels from years ago.

    I feel like it needed a longer grinding time

    I took your data and generated the "Pro-rated cost per gram removed". The pro-rated cost takes into account the amount of the disk used: it is the cost times the percent loss.

    Pro-rated cost per gram removed (x 100)
    % wheel Steel
    Cost loss removed
    Warrior 0.99 1.4 48 0.029
    Dewalt 2.68 0.6 38 0.042
    Makita 2.99 1.3 47 0.083
    Norton 6.28 0.5 35 0.090
    Avanti 2.77 2.0 51 0.109
    Diablo 4.47 2.3 51 0.202

    The Warrior is the clear winner. The Diablo comes out much worse than the Norton because so much of it was lost. A bar graph here:

    I love the thinner 8th In wheels, perfect for grinding stops and starts for pipe welding

    Is there a way you could perhaps test the composite metal cutting discs against the diamond metal cutting discs like Lenox Metalmax? I was wondering about the effectiveness, cost and pollution between them? Thank you for making these test experiments as scientific as possible.

    I would have loved to see the ratio of grams lost to grams removed tbh, but always great to watch your videos

    Great info on grinding wheels. I have searched the channel for a comparison on orbital sanding discs. Especially since the availability of that Diablo product. If there is a video, can someone point me to it? Thanks for all the great info!
