The Starrett SB565Z is an eight-piece brass drive pin punch set to drive pins into or out of a work piece. The set is in a fabric case, and includes pin punches with the following diameters: 1/16 inch, 3/32 inch, 1/8 inch, 5/32 inch, 3/16 inch, 7/32 inch, 1/4 inch, and 5/16 inch. Each pin punch is made from brass, for use with surfaces that could be damaged by harder steel punches. Pin punches are used to place or knock out loosened pins and rivets from workpieces, where they are frequently used to attach something to a rotating shaft. They have a cylindrical body to hold and drive the smaller diameter, flat-ended tip into the workpiece. The L.S. Starrett Company manufactures precision measuring tools, metrology and testing equipment, and saw blade products. The company was founded in 1880 and is headquartered in Athol, MA.
