When it comes to milling components, speed is the name of the game. High speed tools can help you get your work done faster, but running at high speeds and feeds does come with certain risks. Some tools just cannot stand up to the heat and strain experienced at high speeds, while others may not be stable at such high rotational speeds. Today we will be looking at two types of end mills that are designed to deal with high speed chatter, variable helix and variable flute end mills.

While milling machines are amazing tools, having to deal with tool chatter can be a not so amazing side effect of operating one. Tool chatter is a loud sound caused by tool vibrations. If you are sick of dealing with tool chatter then you have probably heard about variable flute end mills. These tools are specially designed to operate at high speeds while minimizing the effects of tool chatter. But are these tools all that they are cracked up to be?
