Per the enclosed ad, it measures the distance from blade to fence so precisely you can cut wood accurate to 10/1000 of an inch.
It produces perfect alignment of the fence and the blade, virtually eliminating kickback, binding, and burning.
It can be used to square saw blades to the table, gauge depth of a cut, and even set inside bevels.
The Paragauge can be used on router tables, band saws, and drill presses, too.
