A tool configured to form four evenly spaced indentations having an indentation radius and four evenly spaced projections about a circumference of a generally cylindrical seamless ferrule having a ferrule radius. Each projection of the four projections has a projection height equal to or less than a height threshold. The tool includes four crimping dies. Each crimping die of the four crimping dies defines a concave crimping surface having the indentation radius. The tool also includes four limiting dies. Each limiting die is located intermediate two adjacent crimping dies of the four crimping dies. Each limiting die defines a limiting surface that is configured to limit a height of each projection to the height threshold.
