Brownells Premium Roll Pin Starter 7-Piece Punch Kit

Constructed from carbon steel, these punches undergo rigorous hardening and tempering processes to enhance their performance. The hardening process increases the steel's resistance to wear and deformation, while tempering ensures that the punches maintain a balance between hardness and toughness. This combination of materials and processes results in a tool that is both robust and reliable, capable of withstanding the demands of repeated use in firearm maintenance.
