Maximum impact energy, measured in joules, indicates the strength of each hammer blow and is crucial for drilling into tough materials like concrete or masonry. Higher impact energy allows for faster drilling and more efficient chiseling. For example, the Festool 18V KHC delivers 2.6 joules of impact energy, making it ideal for heavy-duty applications. If you need a tool for frequent work in hard materials, choosing a hammer drill with higher impact energy is best. With different models offering varied impact energy levels, users can select a tool tailored to their specific needs.
