Abstract:
1. A tool with a replaceable tip, comprising: a tool body comprising a tip holding portion; a tool tip having a shank portion adapted to be disposed proximate the tip holding portion, the shank portion having at least one recess; at least one locking element adapted to be received in the at least one recess; and a clamping ring, an interior diameter of a locking element contacting surface of the clamping ring decreasing in a circumferential direction such that, when the clamping ring is disposed around the tool tip such that the at least one locking element is disposed between the locking element contacting surface and the at least one recess and the clamping ring turns in a first direction about a longitudinal axis of the tool body relative to the tool tip, the locking element contacting surface contacts the at least one locking element and urges it into the at least one recess in the tool tip wherein the locking element contacting surface of the clamping ring comprises a protrusion, the protrusion being disposed at a lesser distance from a longitudinal axis of the tool than the radially furthermost part of the at least one locking element when the at least one locking element is disposed in the at least one recess and, when the clamping ring turns in the first direction relative to the tool tip, the protrusion contacts the at least one locking element and the clamping ring deforms elastically outwardly.
