This operation is mainly used for generating internal profiles in pre-drilled bores.The Tool design allows for the expansion or retraction of the cutter when actuated from rear end. This can be used to produce the required internal profile in the work piece.Bottle boring tools are developed for specific internal profiles of componentsThe internal profile is larger than the tool entry and exit diameters.The operation requires the use of CNC controls to program the various coordinates for the required profile.
