Core Drilling

Core drilling is used when customers require circular openings for new plumbing, fencing and electrical installations.
Core drill is a drill specifically designed to remove an annulus of material rather than an entire cylinder of the material being drilled, as a typical auger – type drill bit would.  The material left inside the drill bit is referred to as the core.

Core dills are used for man applications, either where the core needs to be preserved ( the drilling apparatus for to obtain 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 drill are commonly used in construction to create holes for pipes, manholes and other large diameter penetrations in concrete or stone.

Core drilling is performed when precise, circular diameter cuts are needed.  Holes up to 60 degrees in diameter can be drilled to virtually any depth.  Core drilling is used for plumbing, electrical and HVAC installations.  Line drilling is an effective method for rmoving almost any thickness of concrete where other methods cannot be applied.  Core holes are drilled in a series of overlapping holes, allowing for one large segment to be removed.
