Edge finders, also called wigglers, are used in machining to locate a workpiece's edge accurately. The edge finder is placed in the spindle of a milling machine or drill press and slowly moves toward the processed part. When it touches the edge of the workpiece, it kicks out of alignment, indicating the edge's location. Made in USA.
