Cobore, Inc. has developed tooling for machining unique internal profiles at extreme depths. These features commonly referred to as "bottle boring" are programmable and can be accomplished 20 ft. deep from one end and 40 ft. from both ends. Requirements for machining undercuts, grooves, and reliefs at depths beyond conventional boring methods inspired Cobore to create a new tool that can be run on deep hole drilling machines. Cobore's in house engineering team put their custom tool design expertise to work developing three bottle bore tools that cover a range from 3.816" ID to 8.127" ID.
