Set the heights of router bits and saw blades with greater accuracy! This 3-in-1 digital router combines the functions of three tools: a depth gauge, height gauge and thickness gauge. It is a metal rule with a Super Large LCD display, housed in a heavy-duty polycarbonate frame which allows it to stand freely. The measuring range is 0-6", with a router depth of 0-3.10" and a slot depth of 2.90". It features buttons for on/off as well as zero set functions, and it easily switches readings from inches to metric to fractions at a touch. Two hardened steel measuring anvils (flat and point) are included.
