Concrete coring uses a core drill. Such a drill specifically designed to remove a cylinder of material, much like a hole saw. The material left inside the drill bit is referred to as the core.

Core drills are used for a wide variety of applications either where the core needs to be preserved (which is rarely done in concrete coring), or where drilling can be done more rapidly since much less material needs to be removed than with a standard drill 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.
Core Drilling attaches a diamond-tipped, drum-shaped coring tip mounted to a guiding track to create precise, plum or angled, clean, circular diameter cuts.

ADVANTAGES OF CORE DRILLING

  • Clean, round, accurately sized holes
  • Cored sections safely removed without dangerous dropping of spoils
  • Coring in confined spaces
  • Unlike rotary percussion tools, there is no vibration when core drilling and consequently, no structural damage because reinforcing rods are not loosened.
  • Core Drilling is an economical, quick and clean process whose applications have greatly expanded in recent years. Special equipment enables the drilling of holes up to 48 inches in diameter.
