Accurate measurement is critical to cutting, especially with a table saw or router. Many cuts must be made to extremely specific depths, especially for joinery. Making these measurements with a ruler isn’t sufficient, to obtain the level of accuracy required. The Digital Depth & Height Gauge makes accurate, repeatable settings possible on both of these important woodworking shop tools. Highlights Provides quick and accurate readings of blade and bit height for accurate measurement Large digital display for easy reading in inches or millimeters Magnetic feet hold the gauge firmly to steel or iron tables Can be used horizontally or vertically, allowing the gauge to be used for setting up router table fences Specifications Measuring range: 1 – 3 1/8” (0 – 80mm) Hole depth: 0 – 2” (0 – 50mm) Resolution: 0.0005” (0.01mm) Powered by a single CR2032 3V battery (included)
