In manufacturing, boring is when a single point cutting tool or boring head using several tools creates a larger hole. In order to use a boring machine, a hole must already be drilled or cast into the material, in which the boring machine will hold and drill a larger hole. Boring is useful in manufacturing because it offers precision, achieving ...
