A rotary hammer is a handheld power tool that combines rotational cutting with periodic impact functions. It is primarily used for drilling, grooving, and breaking operations on hard construction materials such as concrete, floors, brick walls, and stone. Its core advantage lies in generating powerful impact force through an internal pneumatic piston structure, making it much more efficient than a regular electric drill.
Main Applicable Materials and Working Modes
Applicable Materials: Specifically designed for high-hardness media, such as reinforced concrete, stone, and brick walls. Some multifunctional models can also be used for drilling wood or metal.
Working Modes
Hammer Drill Mode: Rotation plus impact, most commonly used, suitable for drilling concrete.
Rotary Mode: Rotation only without impact, can be used as a regular electric drill.
Chisel Mode: Impact only without rotation, functioning as an electric pick, used for chiseling or breaking.
Typical Application Scenarios
Construction and Renovation: Drilling holes in walls to install brackets, expansion screws, and wall grooving during plumbing and electrical renovations.
Demolition Work: Using chiseling function to remove old tiles, break concrete layers, or quickly create door openings.
Installation and Maintenance: Installing security equipment, fixing air conditioner brackets, and assembling furniture.
