The gun drill was developed to drill such long, straight holes. Gun drilling is possible over a range of depths and diameters.

The material left inside the drill bit is referred to as the core. Core drills used in metal are called annular cutters. Core drills used for concrete and hard rock generally use industrial diamond grit as the ...
