A hammer drill, also known as an impact drill or percussion drill, is a powerful tool used in construction and DIY projects to drill holes into hard surfaces. It operates on a mechanism that delivers a rapid succession of short, powerful hammer thrusts that pulverize the material and allow for efficient drilling without requiring excessive pressure. They make drilling into materials like concrete, stone, and brick much easier. Hammer drills come in various sizes and power capacities, usually either corded or cordless, and often feature settings to use them as regular drills as well. They are a must-have in the toolbox for heavy-duty drilling tasks.
