- Rifling Methods
- 1. broach, gang — a tool having a series of cutting edges of slightly increasing height used to cut the spiral grooves in a barrel.2. broach, single — a non-adjustable rifling cutter which cuts all of the grooves simultaneously, and is used in a series of increasing dimensions until the desired groove depth is achieved.3. button — a hardened metal plug, called a button, with a rifled cross section configuration. It is pushed or pulled through a drilled and reamed barrel so as to cold form the spiral grooves to the desired depth and twist. When the carbide button was first introduced it was described as a swaging process or swaged rifling.4. hook — a cutting tool which has a hook shape and only cuts one groove at a time.5. scrape — a cutting tool which cuts two opposing grooves at a time.6. swage — an internal mandrel with rifling configuration which forms rifling in the barrel by means of external hammering. Also known as hammer forging.
