With cutting fluid, I got nearly polished cuts. I used this blade in my $200 10" DeWalt chopsaw and the results were great. It actually performs pretty well in wood in a pinch. Definitely clamp things well and make sure your saw is tuned up and squared for best results. I cut quite a bit of 80/20 extrusions (1515, 1530, 3030) and everything turned out clean and accurate. I used my shop vac to catch much of the swarf.
I did find that it works best to have both ends of the piece your are cutting clamped or secured because small pieces can get ejected after the blade goes through. The time saving is worth the price alone. Almost every cut was dead on the measurement. No sanding is necessary and thanks to the miter saw all the cuts are straight.
I bought the blade to cut 1/8" angle and bar aluminum. I've have some Freud router and forstner bits and I would rate them top notch. I didn't run into any kicking while cutting the metal. I just made about 30 cuts in about 45 minutes using my miter saw.
I'm also impressed at how the blade affords very precise cuts. Their saw blades are just as good. This would have taken me hours with a hacksaw. The cuts are also very smooth and clean.
