The DeWALT D25614K-QS rotary hammer is a corded, heavy-duty tool designed for professional drilling and chiselling in concrete and masonry. It is powered by a 1350 W motor and delivers up to 2900 RPM to handle demanding applications. The tool uses an SDS Max chuck system and supports drilling in concrete up to 45 mm diameter. With a robust construction and a weight of 7.8 kg, this rotary hammer is intended for continuous site use where reliable power and impact performance are required.

Advantages

The DeWALT D25614K-QS combines a high-power 1350 W motor with a high no-load speed of 2900 RPM to provide consistent drilling and chiselling performance. Its SDS Max chuck ensures secure bit retention and fast bit changes for large-diameter concrete work. The tool's build and weight offer stability during heavy-duty operations, and the corded AC power supply provides continuous performance without battery limitations.

How to use

Before use, secure the correct SDS Max drill bit or chisel and ensure the tool is connected to a suitable AC power outlet. Select the required mode (drilling, hammer drilling, or chiselling) according to the task. Start the tool at low speed to position the bit, then increase to working speed. Maintain a steady, controlled pressure — let the tool's hammering action do the work rather than forcing it. For chiselling, use controlled strokes and reposition as needed. After finishing, switch off and disconnect the power, then clean the tool and bits to remove dust and debris.

Usage recommendations

Use appropriate personal protective equipment including eye and ear protection, dust mask, and protective gloves. For prolonged or overhead work, ensure additional support or use auxiliary handles to reduce operator fatigue. When drilling deep holes in concrete, periodically withdraw the bit to remove dust and prevent overheating. Store the tool in a dry, cool place and perform regular inspection and maintenance according to the manufacturer's guidelines.
