Core Drilling is used when precise circular diameter openings are required with no dust or vibration through reinforced concrete & block walls, floors and other concrete structures up to 600mm diameter.
Concrete core rigs can be operated vertical or horizontal and at angles.
Core holes are used for utility service instillations such as electrical, plumbing and heating, ventilation or tumble dryers etc.
Core holes can also be drilled in a series of overlapping holes to cut out large square or rectangular openings. This is known as a ‘stitch cutting’.
