The Starrett B565G brass drive pin punch has a 4" overall length with a 1" pin length and 1/4" pin diameter to push pins and rivets into or out of a workpiece. The punch is made from brass, which is softer than hardened steel and better for use on delicate materials. It has a round shank, which is knurled for grip.
Pin punches are used to insert or knock out rivets and pins in assemblies. They have a metal shank on one end and a metal pin driver on the other, and are typically tapped with a hammer.
The L.S. Starrett Company manufactures precision measuring tools, metrology and testing equipment, and saw blade products. The company, founded in 1880, is headquartered in Athol, MA.
