Corded Rotary Hammers (Electric)

Corded Rotary Hammers

Corded rotary hammers are designed for drilling concrete, brick, stone and other hard construction materials and, where supported by the model, for hammer drilling and chiselling. Important selection criteria include impact energy, input power, the SDS tool-holder system, operating modes, drilling capacity and tool weight.

What to Consider When Choosing a Corded Rotary Hammer

• Type of work — determine whether the tool will mainly be used for concrete drilling, hammer drilling, chiselling or several types of work. Learn more in “How to Choose a Rotary Hammer” .
• Impact energy (J) — an important rotary-hammer specification that should be considered together with the intended application and other tool characteristics. “What Is Impact Energy (J)?”
• SDS system — SDS Plus and SDS Max are intended for different tool and accessory classes. Always check the actual tool-holder system before selecting a drill bit or chisel. “Differences Between SDS Plus, SDS Max, and HEX Systems” .
• Input power (W) — power should not be evaluated in isolation. Compare it with impact energy, operating modes and the intended workload. “How to Choose Tool Power (W)” .
• Rotational speed — RPM is relevant during rotary drilling and should be considered together with the material and accessory being used. “What Is Rotational Speed (RPM)?”
• Chuck and accessory compatibility — different tools use different holding systems. Similar appearance alone does not confirm accessory compatibility. “Types of Chucks and Their Applications” .
• Safe operation — use suitable accessories, consider the workpiece material and follow the manufacturer's operating and safety requirements. “How to Use a Rotary Hammer Safely” .
• SDS system maintenance — correct care of the tool holder helps maintain proper accessory installation and operation. “How to Maintain a Rotary Hammer SDS System” .
