4 Jaw Chuck Centraliser
The 4 Jaw Chuck Centralism works by being trapped between the lathe tailstock centre and a centre punched mark on the work piece held in a 4 jaw chuck or on a faceplate. A Dial indicator placed against the centraliser measures the eccentric error as the chuck/ plate is routed, thus allowing correcting adjustment to be made. “Protected” centre at spring loaded telescopic end. Works Quickly and accurately. Precision ground hardened and tempered point. Supplied with a plastic box also.
