Abstract
A drilling tool includes a drive assembly with a shank that is configured to couple to a power tool and a step drill bit. The step drill bit includes a body having a proximal end adjacent the shank, a distal end opposite the proximal end, and a bit axis extending centrally through the body between the proximal end and the distal end. The body is defined by a wall extending around the bit axis to define a hollow interior cavity of the body. The step drill bit also includes a plurality of axially stacked, progressively sized steps with a first step at the proximal end and a terminal step at the distal end and a flute extending from the proximal end to the distal end. The flute defines a cutting edge.
