Accurate electronic edge finder for milling machines and drill presses — fast, reliable edge and center location with 0.005 mm accuracy. Key benefits Saves setup time: locates workpiece edges and positions quickly so you can start machining sooner. Prevents probe damage: spring-loaded probe retracts on contact to reduce the risk of accidental overrun. Clear confirmation: a bright LED and loud audible beep trigger immediately when the probe touches the workpiece, so you get unambiguous feedback even in noisy shops. Precise and repeatable: hardened, ground probe and high accuracy (0.005 mm) support consistent part setup. Features and specifications Function: electronic contact edge/position finder with immediate visual and audible indication on contact. Compatibility: designed for use on milling machines and drill presses; fits toolholders that accept a 20 mm shank. Shank diameter: 20 mm. Probe (tip) diameter: 10 mm. Probe material: hardened and ground for wear resistance and long life. Safety: spring-loaded probe to avoid damage from accidental overruns. Performance: position accuracy 0.005 mm; LED lights and audible beep activate instantly on contact. How it solves common setup problems Eliminates guesswork and manual feeler techniques by providing immediate, repeatable contact detection. Reduces the risk of tip damage and workpiece errors with a spring-loaded, hardened probe that retracts on impact. Improves efficiency in repetitive set-ups where fast, reliable edge finding is required. Practical use scenarios Setting X and Y zero on a milling machine: touch the probe to the workpiece edge, note the contact indication, and set the machine coordinates quickly and accurately. Locating hole patterns before drilling: use the finder to establish precise workpiece edges and transfer those references to drilling locations for consistent hole placement. Rapid fixturing checks: confirm part location after re-clamping or during batch setups to ensure repeatable alignment without time-consuming measurement. What makes it stand out High accuracy (0.005 mm) combined with a hardened, ground 10 mm probe provides both precision and durability. Immediate dual feedback (bright LED + loud beep) is easy to see and hear in a busy workshop. Simple mechanical design — spring-loaded tip prevents damage and reduces downtime for repairs or tip replacement. Ordering details and use notes Verify your machine accepts a 20 mm shank toolholder before ordering. Use gentle feed rates when touching the probe to the workpiece to ensure reliable contact indication and maximum probe life. Compatible for general locating tasks on milling machines and drill presses as described.
