Rotary hammer DeWalt D25333K 950 W, 3.5 J impact, 3.7 kg, SDS-plus, 1150 RPM, 5200 bpm

The Rotary Hammer DeWALT D25333K-QS is a compact, corded hammer drill built for medium-duty drilling and chiselling in masonry and concrete. It integrates a 950 W motor and SDS Plus chuck system to deliver consistent drilling performance and simple bit changes. With an impact energy of 3.5 J and a maximum idle speed of 1150 RPM, the tool is optimized for efficient hole-making and light demolition tasks while remaining portable at 3.7 kg and sized for easy handling.

Advantages

The rotary hammer combines a high-power 950 W motor with an SDS Plus chuck for secure bit retention and quick changes. Its 3.5 J impact energy enables effective penetration into concrete and masonry up to practical working depths, while the moderate no-load speed provides controlled drilling. At 3.7 kg and with compact dimensions, the tool offers reduced operator fatigue and improved manoeuvrability in confined spaces. The corded AC design ensures continuous power for prolonged jobs.

Suitable for

• Drilling anchor and fixing holes in concrete and brick
• Light chiselling and removal of plaster or tile adhesive
• Installing electrical boxes and conduit in masonry walls
• General maintenance and renovation tasks requiring repetitive drilling

How to use

Select an appropriate SDS Plus bit for the required hole diameter and insert it into the chuck until it locks. Secure the workpiece or ensure stable positioning before starting. Connect the tool to a suitable AC power outlet, set the machine to the drilling or hammer mode as needed, and start at low speed to position the bit. Apply steady pressure—avoid forcing the tool—to allow the motor and impact mechanism to work efficiently. Periodically withdraw the bit to clear debris and prevent overheating of the bit and motor. When chiselling, use the correct chisel accessory and adopt controlled passes to remove material evenly.

Usage recommendations

Use appropriate personal protective equipment: safety glasses, hearing protection, dust mask, and gloves. For prolonged operations, allow the tool to rest periodically to prevent motor overheating. Match bit type and size to the material and task, and use a depth stop for consistent hole depths. Ensure the power cord and plug remain undamaged and use a residual current device (RCD) where required by local regulations.
