    I have been playing with a variety of end mills slot bits and standard router bits and the pics are bellow. It seams unless you run at very slow feed rates you get a large amount of tear out with any of the conventional bits and that was with a variety of feeds and speeds.however with the burrs the spindle speed could be significantly lower and feed rate a lot higher and still giving a very clean cut with minimal tear out which is why I have been trying to persue them.
