A part's-eye view of a boring bar. Hole types: Blind hole (left), through hole (middle), interrupted hole (right). In machining, boring is the process of enlarging a hole that has already been drilled (or cast) by means of a single-point cutting tool (or of a boring head containing several such tools), such as in boring a gun barrel or an engine cylinder.

Spud date: When drilling a new well, the spud date is the day on which the main drill bit begins drilling. For onshore drilling, spudding-in occurs after a wellsite has been prepared and a larger surface hole drilled and cased in preparation for the main drill bit to be used. Subsalt: Refers to oil prospects that lie below a salt layer. [7]
Many corporations have such standards, which define some terms and symbols specific to them; on the national and international level, ASME standard Y14.38 [1] is one of the standards. Australia utilises the Technical Drawing standards AS1100.101 (General Principals), AS1100-201 (Mechanical Engineering Drawing) and AS1100-301 (Structural ...
