ABSTRACT:
A tool sleeve rotation limitation system for reducing the rotation of a tool sleeve within a block bore of a support block, the tool sleeve having a sleeve engagement surface and the block bore having a block engagement surface. The tool sleeve rotation limitation system comprises a rotation limitation member located between the tool sleeve and the block bore so as to engage the tool engagement surface and the sleeve engagement surface and reduce rotation of the tool sleeve within the block bore, the rotation limitation member having a member perimeter which conforms to at least one of the sleeve engagement surface and the block engagement surface. Alternatively the tool sleeve rotation limitation system comprises a resilient rotation limitation member located between the tool sleeve and the block bore so as to frictionally engage the tool sleeve and the block bore and reduce rotation of the tool sleeve within the block bore.
