      Overview

      Parallels, straight edges, and surface plates are precision tools used in machining and metalworking. Parallels are used to elevate and align workpieces in a vise, straight edges ensure the flatness of surfaces, and surface plates provide a stable, flat reference plane for measurements and inspections. These tools are essential for achieving high accuracy and precision in various industrial applications.
