Core drilling is also commonly used to create holes for routing cables or placing anchoring bolts, installing load carrying devices like dowel bars, or for analysis of structures, rock or strata.
The core drill can either be hand-held or mounted to the surface that will be drilled. The core drill can be used on concrete and many other surfaces.
Core drills can be operated in any orientation -- on the ground or floor, on a wall, in a ceiling, etc.
