Tool review: Rockler router bit center depth gaugeRockler's new router bit center depth gauge is a clever product that makes router table fence and bit adjustments a snap.
Rockler’s new Router Bit Center Depth Gauge is a clever product that makes router table fence and bit adjustments a snap. The gauge has a robust 12-in. steel rule etched clearly with both metric and imperial measurements. The gauge’s moveable fence, which has a hairline cursor, slides smoothly and locks in place firmly.
To set or measure the cutter height, simply set the movable fence, lock it, and stand the gauge over the bit. The broad foot at the end of the scale makes the tool stable. Adjusting the router table’s fence is where this gauge really shines, though. The tool’s fence niftily registers off the center of a bit via notches that slip around bits with either 1⁄4-in. or 1⁄2-in. shanks. This helps streamline measurements. For example, if you wish to cut a groove, just measure from the center of the groove to the edge of the board, and set the gauge to that distance. It’s that simple. Its offset foot helps the gauge avoid the bit opening in the fence.
