    Isn't the carbide just the small dark teeth on the rollers? Forgive me if I'm asking a dumb question but how do those make up half of the weight of this? Seemed to me that most of the weight is in the huge chunk of steel. I honestly don't know too much about this other than I got with a bunch of stuff from an oil company here in Texas.

    src3collector yes the dark spots are carbide and in your case the bits on yours might way 20 pounds but carbide is heavier than steel because of the density, just like gold it is heavier than it looks. Also have no idea what the op has because he hasn't posted a pic but mining bits come in all shapes and sizes.
