The UJK Digital Height Gauge is an indispensable measuring tool for the accurate setting of cutting depths, in particular, for router cutters and saw blades. The body is CNC machined from 12mm thick phenolic sheet. A hard, dense material, highly durable and most importantly, stable under normal workshop conditions. The gauge is accurate both vertically and horizontally. The integrated digital scale unit with LCD screen offers a read-out in metric or imperial. You can zero the digital read-out at any point, allowing relative adjustment. The display has a resolution of 0.01mm or 0.001 inches. LR44 battery included.
