A toolholder (121, 121', 121") including a cutting head clamping arrangement is provided and includes a body (123, 123', 123") including a first end (125, 125', 125") and a second end (127, 127', 127"), and an axial opening (129, 129', 129") extending from the first end (125, 125', 125") toward the second end (127, 127', 127"). The axial opening (129, 129', 129") of the body (123, 123', 123") includes a first portion (131, 131') having a first diameter and a second portion (147, 147', 147") having a second diameter, the first portion (131, 131') of the axial opening (129, 129', 129") of the body (123, 123', 123") being closer to the first end (125, 125', 125") than the second portion (147, 147', 147") of the axial opening (129, 129', 129") of the body (123, 123', 123") and the first diameter being larger than the second diameter. A rod (151', 151") is movably disposed in the axial opening (129, 129', 129") of the body (123, 123', 123"), the rod (151', 151") including a first end (153') and a second end (155'), and an axial opening (157') defined by a plurality of axially extending fingers (141') at the first end (153') of the rod (151', 151"), the fingers (141') being elastically movable radially outwardly toward the interior surfaces (133) of the first portion (131, 131', 131") of the axial opening (129, 129', 129") of the body (123, 123', 123") upon application of a radially outwardly directed force to the fingers (141'). |
