In the manufacturing of many identical barrels, the extra cost of this special tooling and equipment is easily offset by the improved rate of production. Broaching removes metal in shallow passes with multiple inline cutting surfaces, each progressively larger than the previous.projects.nfstc.org/firearms/module04/fir_m04_t06_…Broaching is one way to produce the spiral grooves needed to spin-stabilize a bullet. A rifling broach has circular working nodes, each with a reverse profile of the rifling pattern. As the broach moves through the barrel, each node shaves off a little metal.nij.ojp.gov/nij-hosted-online-training-courses/firear…

Rifling - Wikipedia
An early method of introducing rifling to a pre-drilled barrel was to use a cutter mounted on a square-section rod, accurately twisted into a spiral of the desired pitch, mounted in two fixed square-section holes. As the cutter was advanced through the barrel it twisted at a uniform rate governed by the pitch. The first cut was shallow. The cutter points were gradually expanded as repeated cuts were made. The blades were in slots in a wooden dowel which were gradually pac…
