The Oneway® Multi-Tip Revolving Center is a multi-purpose center that's designed to perform a number of applications. The body is precision machined from premium alloy steel, heat treated, then nickle plated. In the end of the live center is a 5/8" dia. cup center with a removable center pin. The exterior of the 5/8" cup center is threaded (3/4"-10tpi) to accept either the bull nose cone center (reversible) or full point cone center. The bull nose and full point cone give you the ability to self-center any work up to 3-1/4" diameter. The large bull nose cone can be reversed, permitting self-centering of round or square spindles up to 3".
