Core Drilling

Core drilling techniques are used when precise, circular cuts are needed. Holes of almost any diameter are easily drilled to make openings for plumbing, electrical and HVAC installations. Core drilling is also commonly used to create holes for routing cables or placing anchoring bolts, installing load carrying devices or dowel bars, or for concrete sample analysis.

A core drill bit consists of a steel tube with diamond segments brazed or laser welded on the drilling end. The core bits are mounted on the rotating shaft of various types of drilling machines. Core drills can be operated in any orientation, vertical or horizontal. Core drill machines can be powered by electric, hydraulic or air power sources. Core drill bits can range in diameter from 1/2 - 60 inches (13 - 1524 mm) and drilling depths are virtually unlimited with the barrel extensions.
