Guide attachment for power tools

A distal targeting system, comprising:

• a power tool having a tool body and a receiving element;
• a shaft elongated along an axis extending along a longitudinal direction, a proximal portion of the shaft receivable in the receiving element;
• a field generator having a coupling element configured to receive the shaft;
• and
• a bridge connectable to the field generator so as to be spaced from the field generator in a proximal direction with respect to the axis, the bridge having an attachment device that is connectable to the power tool, wherein the bridge includes a pair of arms configured to clasp the tool body in a manner substantially rigidly coupling the bridge to the power tool, wherein at least one of the arms is positionable with respect to the attachment device at a distance that is adjustable so as to enable the arms to 1) substantially rigidly clasp the tool body, 2) release the tool body, and 3) substantially rigidly clasp a second tool body having one or more of a different size and shape than the tool body.
