Need help?Do you have a question about the NUTOOL NCD18C and is the answer not in the manual?
This document describes a range of Nutool cordless hammer drills, including models NCD18C, NCHD18, NCHD24, NCDL144, and NCDL144-M. These devices are designed for drilling and driving screws, with some models offering a hammer action for masonry work.
The Nutool cordless hammer drills are versatile power tools designed for both drilling and screw driving applications. The core function involves a rotating chuck that holds various drill bits or screwdriver bits. The speed of rotation is variable and controlled by the pressure applied to the trigger switch. A keyless chuck system allows for easy installation and removal of bits.
For screw driving, the tools feature a torque adjuster, which allows the user to set the desired tightening power. This is crucial for different screw diameters and materials, preventing overtightening or stripping. When the preset torque is reached, the chuck stops rotating. The document recommends starting with the lowest torque setting and increasing it as needed. A specific symbol on the torque adjuster indicates the highest torque setting, used for drilling and driving large screws.
Some models, specifically NCHD18, NCHD24, NCDL144, and NCDL144-M, also incorporate a hammer action feature. This allows the tool to drill into masonry by adding a percussive motion to the rotation. The hammer action is engaged by rotating a selector collar until a hammer symbol aligns with an arrow on the chuck body. When using hammer mode, it is essential to use masonry drill bits recommended by the supplier.
The drills also include a forward/reverse switch, typically a slide switch located above the trigger. This switch allows the user to change the direction of rotation, enabling both tightening and loosening of screws, as well as drilling in different directions. For safety during transport, pushing this switch to a central or neutral position renders the drill inoperative, preventing accidental engagement.
Models NCHD18 and NCHD24 are equipped with a 2-speed gearbox, offering high and low-speed ranges. This allows for optimal performance across various tasks, from high-torque screw driving to high-speed drilling. The speed range is selected via a selector switch located on top of the drill.

The drills are designed for ease of use and safety. The variable speed trigger allows for precise control over drilling and driving. The keyless chuck simplifies bit changes. The torque adjustment ensures appropriate power for different tasks, protecting both the workpiece and the tool. The hammer action, where available, enhances versatility for drilling into harder materials like masonry. The forward/reverse switch provides directional control, and the 2-speed gearbox (on NCHD18/NCHD24) optimizes performance for various applications. An LED light is also included for improved visibility in dimly lit work areas.
The battery packs are shipped in a low charge condition and must be fully charged before first use. The charging process involves connecting the charger to a standard 230V~50Hz mains outlet. The charger and battery pack are specifically designed to work together, and using other brands is not recommended. The battery pack has a keyway to ensure it fits into the charger correctly. A red LED indicates charging, and a green LED indicates a full charge. Charging times vary by battery type: fast charge (30-90 minutes), slow charge (3-5 hours), and trickle charge (7-9 hours). It is crucial to fully discharge NiCad/Li-Ion batteries before recharging, except for the initial conditioning of a new battery, and not to exceed the nominal charge time.
Proper maintenance is essential for the longevity and safe operation of the tool. This includes keeping cutting tools sharp and clean, following lubrication instructions, and ensuring handles are dry and free from oil/grease. Ventilation slots must be kept clean to prevent overheating and motor damage.
The manual emphasizes several safety precautions:
The product is fitted with a sealed electric plug compatible with the tool and the power supply of the user's country, complying with international standards. The appliance must be connected to a power supply matching the rating plate. Damaged plugs or power cords must be replaced with identical original units by a qualified electrician. The product is double insulated and does not require an earth connection. The 3-pin plug must comply with BS1363/A, and the fuse must comply with BS1362. If the 13 amp plug needs replacement, the brown wire connects to the live (L) terminal, and the blue wire to the neutral (N) terminal. The outer insulation must be gripped by the cord grip. For outdoor use, the product should not be exposed to rain or dampness, and a suitable residual current device (R.C.D.) is recommended at the socket outlet.
