Drilling tool including a step drill bit

A drilling tool comprising:

• a drive assembly including a shank that is configured to couple to a power tool;
• and
• a step drill bit including
• 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 being defined by a wall extending around the bit axis to define a hollow interior cavity of the body, the wall extending from the proximal end to the distal end, the body including a drive socket that receives the drive assembly, the drive socket positioned within the hollow interior cavity, the drive socket is defined by a plurality of inner faces that are spaced and separate from the wall,
• a plurality of axially stacked, progressively sized steps including 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 defining a cutting edge,
• wherein the bit axis extends through the hollow interior cavity.
