Phenomenal bit! I had to make about a hundred curly maple display panels that required cutting both the edge and the end. If I didn't have to worry about tearing the end grains let alone the cross grains of figured maple I would have saved hours (which =$$). This bit will cut through any board leaving the glass surface with no burn through and absolutely no cracks. The last haircut was just as perfect as the first. I've tried dozens of samples and there is absolutely no comparison to this beast. It's expensive, but I'd pay twice as much if I had to do it again.
