A core bit is a specialized drilling tool.
Often an operator uses it to remove an intact core sample from something,
such as a rock sample.
In other applications, core bits drill large diameter holes such as sink cutouts
and passages for wires.
Core bits are useful in various commercial and research applications,
including geological surveys and oceanic studies.
Other types of core bits enlarge pre-drilled or cast holes, but these are solid bits that do not remove intact cores.
