<p>A tool holder (100, 200, 300, 400, 500) includes a shank (12) including a tool holder portion (12a) and a central bore (12d) for accommodating a cutting tool (14), and a first shrink fit sleeve (102, 202, 302, 402, 502) disposed about the tool holder portion (12a) of the shank (12). An application of heat to the tool holder causes the tool holder portion and the first shrink fit sleeve (102, 202, 302, 402, 502) to expand outwardly, and the removal of heat will cause the tool holder portion and the first shrink fit sleeve to contract inwardly to rigidly maintain the cutting tool (14) within the tool holder by shrink fit. The tool holder (400, 500) may also include a second shrink fit sleeve (404, 504) disposed about the first shrink fit sleeve (402, 502) to provide increased torque capability.</p> |
