Hello

I have been using straight fluted cutting bits predominantly until now. I now have work that would definitely benefit from switching over to a more effective spiral bit type. I understand that spiral bits cut "better" than straight fluted bits and that, generally, more flutes is better but I don't REALLY understand this. Before I start buying two or three fluted spiral cut end mills for my wood working I want to know as much as I can about which is right for me. Does anyone have some time to spare or a good link to send me to?
