Core drill
From Wikipedia, the free encyclopedia
A core drill is a drill specifically designed to remove a cylinder of material. The material left inside the drill bit is referred to as the core.
Core drills are used for many applications, either where the core needs to be preserved (the drilling apparatus used in obtaining a core sample is often referred to as a corer), or where drilling can be done more rapidly since much less material needs to be removed than with a standard bit. This is the reason that diamond-tipped core drills are commonly used in construction to create holes for pipes, manholes, and other large-diameter penetrations in concrete or stone.
