Technical Field

Background

Boring is an internal diameter cutting process that enlarges a hole or other circular profile with a tool, typically a single-edged boring tool (known as a boring bar), which has applications ranging from semi-roughing to finishing. The boring tool has three basic elements: indexable inserts, cutter bars and boring seats. The boring holder is used to hold a tool shank, typically about 4 times the diameter of the tool shank. The length of the tool shank carrying the cutting insert protruding from the boring holder is called the overhang (unsupported portion of the boring tool). The overhang determines the maximum depth of a boring hole, and is the most important size of the boring cutter.
