Reliable Core Drilling

McGrath Electrical & Data provides precise core drilling for installations throughout Grafton, Ballina, Casino, Yamba, Woolgoolga, Coffs Harbour and surrounding NSW North Coast areas.

We can drill neat circular holes in difficult-to-penetrate materials, including precast and reinforced concrete, asphalt, brick, and various other construction materials. These holes allow for convenient routing of conduit piping, electrical wires, HVAC ducting, plumbing pipes, data cables and more.

Holes can be drilled on an angle; above-ground, subterranean, and under water. We have core drilling capability ranging from 0 – 180 mm in diameter and 0 – 60 mm in depth. In most cases, we use a circular wire saw in conjunction with a diamond-tipped core bit.
