Abstract
A tool holder device. The tool holder comprises a shank having a first shank portion and a second shank portion. The tool holder also comprises an end component having a first component portion and a second component portion. An expansion member is configured to surround the first shank portion and the first component portion wherein the expansion member expands as the shank is engaged with the end component. Additionally, a method of fastening a tool comprises positioning an expansion member around a shank and positioning an end component partially within the expansion member. Next the end component is connected to the shank wherein the shank is inserted within a spindle bore. Then, the expansion member is expanded against the spindle bore to secure the shank within the spindle bore.

A tool holder device, comprising:
- a shank, the shank having a first shank portion and a second shank portion;
- an end component, the end component having a first component portion and a second component portion, the end component being removably engaged with the shank;
- and
- an expansion member, the expansion member being configured to surround the first shank portion and the first component portion wherein the expansion member expands as the shank is engaged with the end component.
A tool holder device which fastens a tool in the centerline axis of rotation of a spindle, comprising:
- a shank, the shank removably connected to the spindle, the shank having a first shank portion, a second shank portion and a body, the body separating the first shank portion and the second shank portion such that the first shank portion and the second shank portion taper toward the body;
- an end component, the end component having a first component portion and a second component portion, the end component being removably engaged with the second shank portion;
- and
- an expansion member, the expansion member comprising a first expansion portion and a second expansion portion wherein the first shank portion nests within the first expansion portion and the first component portion nests within the second expansion portion such that the expansion member expands against the spindle as the shank is engaged with the end component to fasten the tool in the centerline axis of rotation of the spindle.
A method of fastening a tool, comprising:
- positioning an expansion member around a shank;
- positioning an end component partially within the expansion member;
- connecting the end component to the shank;
- inserting the shank within a spindle bore;
- and
- expanding the expansion member against the spindle bore to secure the shank within the spindle bore.
