The good folks over at Rockler posted a great article on their blog recently about how to select the proper blade for your sliding compound miter saw and/or radial arm saw. In their words:
Have you ever used a radial arm saw that seemed to move through the material a little too easily, as if the blade was pulling itself through the cut? Or maybe you’ve used a sliding compound miter saw and felt the material you were cutting lift off of the surface of the saw during the cut. If you have, there’s a good chance that the saw wasn’t outfitted with the right blade.
In short, they recommend a less aggressive blade for these tools, but you should check out the article for more information.
