A Handy Drill Gauge
Drill Gauge
The accompanying sketch shows a simple drill gauge which will be found very handy for amateurs. The gauge consists of a piece of hard wood, 3/4 in. thick, with a width and length that will be suitable for the size and number of drills you have on hand. Drill a hole through the wood with each drill you have and place a screw eye in one end to be used as a hanger. When you want to drill a hole for a pipe, bolt, screw, etc., you take the gauge and find what size drill must be used in drilling the hole.
