An interlocking collet system comprising:

• an attachment comprising first and second attachment surfaces spaced from one another;
• and
• a collet for selectively retaining the attachment, the collet comprising:
• a housing configured to extend along an axis between first and second ends and defining a bore along the axis for selectively disposing and retaining the attachment therein in an installed position;
• first and second locking members disposed within the bore of the housing and each being moveable along the axis;
• and
• at least one bias member disposed within the bore of the housing, with the at least one bias member arranged to position the first locking member along the axis in a first position in which the first locking member is configured to contact the first attachment surface of the attachment and with the at least one bias member arranged to position the second locking member along the axis in a second position in which the second locking member is configured to contact the second attachment surface of the attachment, and wherein the first and second locking members in the first and second positions, respectively, are configured to exert opposing axial forces on the attachment.
