If you've not already read the description of the process of broach rifling, here's a link to that article again: Rifling: Manufacturing: Broach Rifling.
Now that you've read about the process, let's look at a movie demonstrating the process in action:
This video comes to us from a company called Miles Broaching, a manufacturer of broaching tools for several applications. In the above video, they demonstrate using a broaching tool to produce rifling for a handgun barrel. As you can see, the process happens pretty quickly, much faster than the cut rifling process we studied in the previous post.
