Diamond Coring Bits

A core drill is 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 used in metal are called annular cutters. Core drills used for concrete are generally called Diamond Core Drills and are water cooled. For drilling masonry, carbide core drills can be used.

Diamond core drilling is a high-speed, high-production method of drilling in concrete, stone, asphalt or masonry structures. It is fast, safe, quiet and does not cause impact or vibration damage to the immediate surrounding structure. Diamond core drilling minimizes spalling, eliminates fractures and doesn’t transfer vibrations to the surrounding structure. The clean, straight openings require no patching or other cosmetic repair and allow the next operation to be installed or carried out without further delay. Core drills cut easily through rebar, allowing the holes to be placed wherever it is most suitable. Holes of almost any diameter up to 60 inches are easily drilled to make openings for plumbing, electrical and HVAC installations.

Diamond core drilling is so called because it uses a ‘diamond bit’. This drill bit is composed of group of small, industrial grade diamonds set into a metallic, soft matrix. As the ground is drilled, this matrix will wear away and expose more diamonds.
