## Long description

The DeWALT D25144K rotary hammer is a 900W SDS Plus tool designed for drilling and light chiselling in concrete, masonry, wood and steel. It delivers up to 3 J impact energy, a maximum idle speed of 1450 RPM and supports drilling diameters in concrete up to 28 mm and in wood up to 30 mm. The compact and ergonomic design, 3.1 kg weight and improved sealing for dust protection make it suitable for construction and renovation tasks where reliable performance and durability are required.
Advantages
The tool features a large hammer mechanism for high performance with reduced stress on components, a mechanical clutch to prevent sudden high‑torque reaction if a bit jams, and electronic variable speed for precise control. It offers multiple operating modes including rotation‑stop for light chiselling and impact‑stop for standard drilling and screwdriving using the Quick Change removable chuck. Ergonomic rubber‑coated back and side handles and rounded industrial design improve handling and user comfort, while output air slots and improved sealing protect both the user and internal parts from dust.
Suitable for
Drilling anchor and fixing holes in concrete and masonry (4–28 mm)
Light chiselling in brick and soft masonry
Drilling in wood and steel using the removable chuck (wood up to 30 mm, steel up to 13 mm)

How to use
Select the appropriate bit and operating mode for the task: use hammer mode with the SDS Plus bit for concrete and masonry drilling, rotation‑stop for light chiselling, or switch to the Quick Change removable chuck and impact‑stop for drilling in wood, steel or for screwdriving. Set the electronic variable speed to match the material and apply steady pressure while maintaining correct alignment. If the bit binds, the mechanical clutch reduces reaction torque; stop the tool and clear the obstruction before resuming. Maintain airflow clearance at the output slots and avoid covering ventilation during use.
Usage recommendations
Use suitable personal protective equipment (safety glasses, dust mask, hearing protection and gloves). Choose SDS Plus bits rated for the required diameter and material. For prolonged drilling in dusty environments, clean tool seals and keep ventilation slots unobstructed to preserve performance and service life.
