Core drilling

Core drilling is a preferred method for many contractors because it produces minimal vibration and noise, allowing work to be carried out with minimal disruption to surrounding areas. This makes it ideal for sensitive environments such as offices, hospitals, airports, and residential properties.

Why Choose Core Drilling?

Core drilling is a preferred method for many contractors because it produces minimal vibration and noise, allowing work to be carried out with minimal disruption to surrounding areas. This makes it ideal for sensitive environments such as offices, hospitals, airports, and residential properties.

The work can be carried out wet or dry, making core drilling a fast, clean, and efficient method for creating perfectly formed holes ranging from 6mm up to 1M in diameter. Holes are drilled precisely to your requirements, and because the structural integrity of the building remains virtually untouched, labour for any making-good work is significantly reduced.

Core drilling is carried out using electric motors or hydraulic equipment, both of which are fully self-sufficient. If a power supply is not available on site, A1 Kiwi Cutters & Drillers can provide generators, petrol, or electric hydraulic power packs, ensuring the job is completed smoothly and efficiently with minimal hassle for our clients.
