Digital Edge Finder (Light & Buzzer Sound)

Improve your machining accuracy with this precision Optical Edge Finder, designed for quick and reliable edge detection in milling, drilling, and CNC operations.

This tool features a bright red LED indicator combined with an audible beep alert, ensuring you never miss the exact contact point—even when working in deep holes or low-visibility areas. The integrated steel ball probe allows accurate edge finding inside narrow or hard-to-reach spaces.

Built for durability, the edge finder offers water-resistant performance and stable operation in workshop environments. Its high concentricity ensures precise alignment, helping you achieve repeatable and consistent results.

How to use the Edge Finder Sound?

1. Mount the Edge Finder into the tool holder and check if its concentricity is within 0.005mm.
2. Move the work table to make the edge of the workpiece touch the ball of Edge Finder until the red lamp is on.
3. Mark the reading dial of table movement, backward the table a little, and re-touch the workpiece to Edge Finder slightly until the red lamp is on again to make sure of the correct dial reading.
4. Zero the reading dial and move the table to the desired position by adding 5mm to the desired dimension X.
5. Take off the Edge Finder and remount the desired tooling for machining.
