Big Horn 19277 9 Piece Roll Pin Punch Set

Nine-piece roll pin punch set

This Big Horn 19277 set contains nine punches designed to drive out or insert hollow pins and springs without damage. A guide ball tip centres itself for precise alignment in the pin while the shoulder maintains full, even contact. Each piece is made from premium high carbon steel and individually heat-treated for a hardened tip and a softer striking end that absorbs hammer blows without chipping. The set is finished in red, black and silver.

Gunsmiths, machinists

The set suits anyone who regularly removes or installs roll pins in firearms, machinery or small equipment. The self-centring tip reduces the risk of marring surrounding surfaces during alignment. Buyers who need solid pin punches, drift punches or automatic centre punches should look at a different tool set because this kit addresses only hollow roll pins and springs.

Nine individual heat-treated punches

The defining specification is the nine individually heat-treated high carbon steel punches with guide ball tips. This construction hardens the working tip for durability while keeping the striking end soft enough to withstand repeated hammer impacts. The piece count and heat-treatment process determine whether the kit covers the range of pin diameters a user encounters in gun bolt catch work or general machine service.
