The Starrett 264B Center Punch measures 3-1/4" long and has a 3/8" thick square shank with a 5/64" (2mm) diameter tapered tip. The punch has a hardened steel shaft for strength and a hardened steel tip for wear resistance. The shaft is knurled for the handle and has a square shape to prevent it from rolling when placed on a work surface. Punches make small dimples in a workpiece to guide a drill. Manual punches have a metal shaft with tip and are usually used with a ball hammer to mark the material. The automatic center punches have an internal spring mechanism that allows them to mark the material without using a hammer, leaving one hand free to stabilize the work. The L.S. Starrett Company manufactures precision measuring tools, metrology, testing equipment and saw blade products. Founded in 1880, the company is headquartered in Athol, MA.
