- An electronic optical edge finder that quickly locates the edge of a workpiece, saving setup time on milling machines, jig drills, and similar equipment. - Pro-be hardened and precision ground; does not need to be rotated during measurement. The sensor is spring loaded to prevent accidental damage from overrun. - LED lights up instantly and there is an audible signal when Pro-be touches a conductive workpiece; the indication is louder and brighter at contact. - Specified dimensions and accuracy: Shank Diameter 20 mm, Pro-be Diameter 10 mm, Accuracy 0.005 mm. - Use scenarios: - Quickly set a precise edge reference or zero point on a milling machine to guide tool paths. - Align fixtures or drilling templates on jig boring setups or drill presses using an edge reference. - Verify edge position on conductive workpieces in production or workshop settings to reduce setup time and improve repeatability.
