This digital depth gauge is a versatile precision tool designed for both horizontal and vertical measurements, commonly used in woodworking for tasks like setting the height of router bits and saw blades. It features a large, easy-to-read LCD display that provides intuitive readings in millimeters, decimal inches, or fractional inches, with an accuracy typically around 0.1mm. The device is self-standing with magnetic feet to ensure stability on ferromagnetic surfaces, and it includes a removable measuring rod or pin for accurately checking hole depths, mortises, or slots.
