- Trying to wrap my mind around this tool. One of the bullet points says that only one tool needed for right or left hand threads. Howdeydodat?

The rotation direction of the threading pattern. Same tool goes either left or right turns.

Looking at a picture of the tool on the web site, it basically looks similar to a highly modified tap, fitted to a high helix end mill. I realize that's a bit of a generalization for a thread mill, but I must be a bit dense, because I still don't see how you could cut both right hand and left hand threads using this mill. Do they put right hand threads on one flute and left hand threads on the other flute? I can understand how they do it on a lathe type tool, where the cutting bit has just the teeth cut into the tool with the pitch of the threads, but the milling cutter looks like it has developed thread patterns that extend around the mill for the width of the flute. Wouldn't reversing the direction of the spin just back out the tool from the hole?
