Call Cobore for Bottle Boring Projects in Germany, Mexico, the U.S. & More

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 feet deep from one end and 40 feet from both ends. The need for machining that undercuts, grooves, and relieves at depths beyond conventional boring methods is what inspired Cobore to create a new tool that can be run on deep hole drilling machines.
