In case you don't know, the tube WILL catch the teeth and rotate, usually kinking the blade. Tubing is VERY difficult to cut with a saw blade. For cutting tubes, we clamp in a vise and use a hacksaw. Putting them in the sawframe, so you PULL to cut, works better than pushing.
We buy blades from MSC. They are yellow-Red Streaks. Lenox blades work well also. Buy parrafin wax. and rub it on both sides of the blade, AND be sure to get it into the teeth. It will help keep the chips from "Sticking" to the teeth. That's where the trouble starts.
