ID CDC-110 ELECTRIC CORE DRILL MACHINE [G-240V] - 21662

Yes, absolutely. This machine operates on 220–240V at 50/60Hz, which is fully compatible with the UAE's standard power supply. It also comes fitted with a Type G British 3-Pin plug, which is the standard plug type used across the UAE, making it ready to use straight out of the box with no adapters or rewiring required.

A standard rotary hammer drill uses a percussive hammering action and is best suited for smaller holes, typically under 50mm. This 1800W core drill machine uses a rotating diamond or carbide-tipped core bit to cut clean, large-diameter holes — up to 110mm in concrete and 160mm in brick — without the cracking or spalling that a hammer drill would cause. For pipe sleeves, conduit runs, and anchor installations requiring a clean bore, a core drill is the professional choice.

This machine ships as a comprehensive kit. Included in the PVC carrying case are the core drill machine itself, an auto-stop carbon brush set, an open-end wrench, a water hose, and a 3-metre water pipe for setting up the water cooling system, along with a guide book. You will need to source a compatible core drill bit separately, sized to your required hole diameter (up to 110mm for concrete or 160mm for brick).

This machine has a maximum drilling capacity of 110mm in concrete and 160mm in brick wall. These capacities refer to the maximum core bit diameter the machine can drive effectively. For holes larger than these dimensions, a higher-class core drilling rig with a stand mount would be required.

Water is used as a coolant and lubricant during core drilling. The friction generated when cutting through hard materials like concrete generates significant heat, which can rapidly degrade or destroy a core bit. The included water hose and 3-metre water pipe allow you to feed a continuous flow of water to the cutting face, keeping the bit cool, extending its service life, and also suppressing concrete dust — an important health and safety consideration on site.

The auto-stop carbon brush set is a motor protection feature. Carbon brushes are wear components inside the motor that conduct electrical current to the rotating armature. As they wear down over time with use, the auto-stop design automatically cuts power to the motor when the brushes reach the end of their service life. This prevents the motor from running without adequate brush contact, which could cause serious internal motor damage. A replacement pair is included in the kit so you can keep the machine running with minimal downtime.

If the machine stops unexpectedly during use, the most likely cause is that the auto-stop carbon brushes have reached the end of their service life and have automatically cut power to protect the motor. Check the carbon brush holders and replace the brushes with the spare auto-stop carbon set included in your kit. Also ensure the machine has not overheated — allow it to cool for 15–20 minutes before restarting. If the issue persists after replacing the brushes, check your power supply and consult the included guide book.

Rapid bit wear and overheating are almost always caused by insufficient water cooling. Ensure your water supply is connected via the included water hose and water pipe and that water is flowing continuously to the cutting face throughout the drilling operation. Also check that you are not applying excessive downward pressure — let the bit do the work at a consistent, moderate feed rate. Running the machine at an appropriate speed for the material and bit diameter will also significantly extend bit life.

Some vibration is normal during core drilling, particularly when starting a cut or drilling through reinforced concrete. However, excessive vibration is usually a sign of one of the following: the core bit is worn or damaged and needs replacing; the bit is not correctly and fully tightened onto the machine spindle (use the included open-end wrench to secure it properly); or the machine is being used at too high a speed for the material. Start at a lower speed setting, ensure the bit is secure, and increase speed gradually once the cut is established.
