ABSTRACT:
A tool is disclosed that offers precision fine adjustment of a cutting tool bit on the tool, having an opening provided with a conical seat, an internally-threaded tool adjustment cartridge having a conical surface engageable with the conical seat, an externally-threaded tool ajustment member threadably engaged within the cartridge, a tensioning mechanism for maintaining the conical surface in self-centering engagement with the conical seat, external gear teeth on the cartridge, and a worm wheel engageable with the external gear teeth of the cartridge to provide for very small movements of the cartridge. Fine adjustment can be performed automatically or manually, and may be performed by access to either axial end of the tool, or to the side thereof adjacent the tool bit.
