No, the E-Drill confirms that it has a complete circuit before any voltage is sent to the ground pin and electrode. If it is held against the skin, there is no completed circuit.

A traditional drill can easily damage the skin when the drill bit head slips off the fastener and contacts the skin. The E-Drill, with a near forceless process, significantly reduces the opportunity for damage. When the E-Drill is used improperly, is not lined up with the fastener head or is not concentric with the center of the fastener, it can "burn" the edge of the fastener hole. The repair is similar to the repair for a miss-drill, namely, a single oversize will generally remove the damage. Holes must be inspected to ensure that there is no damage.

Because the E-Drill limits it's drilling depth to just below the fillet head of the fastener, no contact is made with the underlying structural components.


The E-Drill hand held terminal will warn the user when it is time to refill the water tank and when it is time to empty and clean the sediment tanks. If it is not done according to the warning, the E-Drill will stop operating until it has been properly serviced by the technician.
