Achieve flawless batch consistency and precise axial positioning of short parts within turning centers using industrial-grade Workpiece Backstops (lathe chuck stops). Designed to mount securely onto standard 3-jaw power or scroll chucks, this precision spider-style stop system provides a rigid, perfectly parallel reference surface inside the chuck bore. Outfitted with adjustable threaded extension pins that can be positioned at various radial diameters, it prevents part push-back or axial displacement during heavy face milling and aggressive turning, eliminating the need to use loose shop parallels.
