The present invention provides an automated data destruction system to remove data effectively and reliably from a mobile communication device. The system comprises a platform, a securement mechanism, a positioning mechanism, a power drill, a vision recognition system, and a controlling system. The vision recognition system and the processor identify the mobile communication device, and the controlling system controls the securement mechanism, the positioning mechanism, and the power drill to a corresponding location based on the identified mobile communication device and activates the power drill to penetrate the mobile communication device at an exact depth to restrict the damage to the flash memory chip.

A drill bit includes a shank extending along a bit axis and a body portion coupled to the shank. The body portion having a distal end and defining a plurality of axially stacked, progressively sized steps. The body portion defining a body flute having a flute surface. The drill bit includes a first indicium formed on the flute surface adjacent a first step of the plurality of steps, the first indicium including a number and an indicator band around the number and a second indicium formed on the flute surface adjacent a second step of the plurality of steps and spaced from the first indicium, the second indicium including a number and an indicator band around the number, wherein the first indicium is spaced from the second indicium by at least one step of the plurality of steps.
