Stand-mounted core drill
The machine is anchored to the wall or floor so the hole stays straight and square.
Core drilling in Dammam and the Eastern Province
Clean round holes in concrete walls and slabs with a diamond core drill, for AC, plumbing, electrical, ventilation and extractor runs.
- AC and plumbing penetrations
- Hole diameters matched to the pipe
- Through walls, slabs and floors
About Core drilling
A core hole is a round opening of a set diameter cut with a hollow diamond bit, so the concrete core comes out whole and the hole keeps clean edges with no breakage around it. We use it for central and split AC pipes, drainage and water lines, cables, ventilation ducts and extractors, and at the corners of large openings before they are cut. We pick the bit diameter to suit the pipe, fix the machine on a stand so the hole stays straight, and cool with water to keep dust down.

Methods and equipment
How we do it and with what equipment
Diamond bits in several diameters
We choose the diameter that suits the pipe or duct going through.
Water cooling
Protects the bit and cuts dust, with the area protected from water.
Checking services before drilling
We check visible electrical and water routes and any available drawings before fixing the hole position.
How it is done
How Core drilling is done
- 1
Position and diameter
We set the position and diameter of each hole for the AC unit or pipe and check what is behind the wall.
- 2
Fixing the machine
We fix the stand and set the hole straight or at the fall needed for drainage.
- 3
Coring
We cut the hole with the diamond bit under cooling; the concrete core comes out in one piece.
- 4
Clean-up
We remove the core, water and dust and hand over the hole ready for the installation.

Questions about Core drilling
Which core hole sizes are available?
We choose the bit size for what will pass through: AC pipes, drainage, cables or a vent duct. Tell us the purpose and we set the size at inspection.
Can you core through a ceiling slab?
Yes, we core through floor slabs for pipes and ducts, after checking the position against beams and rebar.
Does coring damage the paint around the hole?
The core drill cuts the hole with clean edges and no breaking around it, so the paint and finish usually stay intact.
What if there is rebar behind the wall?
The diamond bit cuts both steel and concrete, but we prefer to avoid main bars in structural members and choose the best position at inspection.
How is core drilling priced?
By the hole diameter, the concrete thickness, the number of holes and where they are; it is set after inspection.
