Claim:
1. A honing tool holder, comprising a body having a mounting element for cooperatively mounting the tool holder on a spindle of a machine tool for rotation therewith about a rotational axis therethrough and axial stroking movements, and a tool holding element opposite the mounting element configured and operable to cooperatively hold a honing tool for rotation about the rotational axis; and a feed system carried entirely on the body, comprising a feed rod assembly supported for axial movement within the body and configured to connect to a feed element of a honing tool when held by the tool holding element, to control radial movements of honing elements of the tool, and a centrifugal force operated mechanism cooperatively engageable with an element of or connected to the feed rod assembly and operable to control at least an initial axial movement thereof, the centrifugal force operated mechanism including at least one weight restrained for radial movement only, including radial outward movement to allow the axial movement of the element of the feed rod assembly, and at least one biasing element disposed to move the at least one weight radially inwardly when the centrifugal force is reduced.
