Tool holder system and method of use

A method of mounting a cutting tool within a tool holder for use in the rotating spindle having a central axis of a machine tool to permit selective adjustment of the axial position of said cutting tool within said tool holder comprising the steps of:

• inserting an elongate member into an axial threaded aperture extending from one end of said tool holder into a second aperture extending from the opposite end of said tool holder,said apertures having axes aligned with said central axis, said elongate member having a first threaded portion sized to threadingly engage said axial threaded aperture and a second threaded portion sized to extend within said second aperture formed in said tool holder;
• inserting the shank portion of said cutting tool within said second aperture to threadingly engage a threaded aperture formed in the shank portion of said cutting tool with said second threaded portion of said elongate member;
• restraining rotational movement of said shank portion of said cutting tool within said second aperture formed in said tool holder by use of cooperating means on said shank and in said second aperture;
• and
• rotating said first threaded portion of said elongate member within said axially threaded aperture in a first direction to cause said cutting tool to axially reciprocate outwardly along the length of said second aperture formed in said tool holder and in a second direction to cause said cutting tool to axially reciprocate inwardly along the length of said second aperture formed in said tool holder whereby a desired axial position of said cutting tool is achieved.
