ABSTRACT:
A cutting tool retention system for retaining a cutting tool having a tool recess. The cutting tool retention system comprises a support block having a block bore and a block recess intersecting the block bore and a clip movably situated in the block recess, the clip having a spring structure which engages the support block and urges the clip into an engaging relationship with the tool recess of the cutting tool situated within the block bore, the spring structure allowing the clip to be disengaged from an engaging relationship with the tool recess of the cutting tool situated within the block bore by applying force directly to the clip so as to overcome the urging of the spring structure.
