1. A distal tip of a surgical tool, the distal tip comprising:
a tip body comprising:
a distal end portion defining an attachment surface, and
an elongate member configured to be inserted within a tubular shaft of the surgical tool and defining a recessed channel that terminates at the distal end portion, wherein the elongate member defines:
a first annular sidewall sized to be inserted into the tubular shaft to form a first slip fit with an inner surface of the tubular shaft, and
a second annular sidewall spaced longitudinally apart from the first annular sidewall such that the first and second annular sidewalls are separate from each other, the second annular sidewall being sized to be inserted into the tubular shaft to form a second slip fit with the inner surface of the tubular shaft; and
an expandable member extending around the tip body, being secured to the attachment surface with a chemical bond, and being adjustable between:
an expanded configuration in which at least a portion of the expandable member extends radially outward from the tip body, and
a collapsed configuration in which at least the portion of the expandable member is oriented substantially parallel to the tip body.
