ID CDC135 [ID CDC 130H] [5.5"] ELECTRIC CORE DRILL MACHINE [G-240V] - 27133

Yes, absolutely. The ID CDC135 is rated at 220–240V / 50–60Hz and comes pre-fitted with a Type G British 3-Pin plug, which is the standard plug type used in the UAE and across the GCC. You can plug it directly into any standard UAE wall socket without needing an adapter or voltage converter.

A core drill machine is specifically designed to cut large-diameter, clean cylindrical holes using a hollow diamond-tipped core bit, removing a solid plug of material. A rotary hammer drill uses a solid bit and a hammering action to break and chip material, making it suitable for smaller holes and anchor fixing. For applications requiring holes larger than approximately 50mm — such as pipe sleeves, conduit runs, or HVAC penetrations — a core drill like the CDC135 (up to 130mm capacity) is the correct and far more efficient tool.

The CDC135 has a net weight of 11.6 kg. For a professional-grade core drill with an 1800W motor and 130mm drilling capacity, this is a well-balanced weight that allows for both handheld use on walls and rig-mounted use on floors. It is manageable for a single operator and practical enough to carry between floors or into confined spaces on a typical construction site.

The ID CDC135 has a maximum drilling capacity of 130mm in diameter. This covers the vast majority of common core drilling tasks on construction sites, including holes for water supply pipes, drainage lines, electrical conduits, HVAC sleeves, and anchor bolts. For reference, 130mm is approximately 5 inches in diameter.

Core drilling through hard materials like concrete, stone, and asphalt generates significant heat at the cutting face. It is standard practice — and strongly recommended — to use water as a coolant when operating a core drill, as this extends the life of the diamond core bit and improves cutting efficiency. The double-insulated design of the CDC135 provides an important safety advantage in wet drilling environments, as the electrical components are fully isolated from the outer casing.

The CDC135 features a variable no-load speed range of 0 to 1,200 RPM. This allows the operator to select the appropriate speed for the core bit size and material. As a general rule, larger diameter core bits require lower RPM to maintain cutting efficiency and prevent premature bit wear, while smaller bits can operate at higher speeds. The variable speed control gives professionals the flexibility to optimise performance across different job requirements.

If the CDC135 becomes excessively hot during operation, stop drilling immediately and allow the motor to cool down before resuming work. To prevent overheating: ensure you are using the correct core bit size for the material, use water cooling consistently during drilling, avoid forcing the machine — let the bit do the work at the appropriate speed, and do not run the motor continuously for extended periods without short rest intervals. The 1800W heavy-duty motor is engineered for durability, but like all power tools, it performs best when operated within its design parameters.

Reduced cutting performance is most commonly caused by one of the following: the core bit is worn or glazed and needs to be dressed or replaced; the drilling speed is too high for the bit diameter — reduce the RPM using the variable speed control; insufficient water cooling is causing the diamond segments to overheat and lose cutting ability; or the machine is being pushed too hard into the material — apply steady, moderate pressure and allow the 1800W motor to drive the cut at its own pace. Always ensure you are using a core bit rated for the material you are drilling.

The CDC135 is equipped with Class II double insulation, which means the internal electrical components are isolated from the outer casing by two independent layers of insulation — a critical safety feature for core drilling, which routinely involves the use of water as a coolant. While the double-insulated design significantly reduces the risk of electric shock in wet conditions, operators should always follow standard electrical safety practices: use an RCD (Residual Current Device) on the supply circuit, avoid submerging the machine, keep the power cable clear of water, and inspect the tool and cable for damage before each use.
