SDS Rotary Hammer Machine

An SDS Rotary Hammer Machine, commonly known as a Hilti machine or demolition hammer on construction sites, is a heavy-duty power tool designed for drilling, chiseling, and breaking extremely hard materials such as concrete, masonry, and stone. Unlike standard impact drills, it uses a pneumatic hammer mechanism to deliver powerful impact force directly to the drill bit, making it ideal for demanding construction applications. It is widely used for drilling anchor holes in reinforced concrete, creating openings for plumbing and electrical installations, and performing light demolition work such as removing tiles, plaster, and concrete sections. SDS (Slotted Drive System) technology allows drill bits and chisels to lock securely while moving freely for improved impact efficiency and reduced slipping. Available in SDS-Plus and SDS-Max configurations, SDS-Plus models are suitable for general construction tasks and anchor drilling, while SDS-Max machines are designed for heavy-duty demolition and large-scale concrete breaking. Modern SDS rotary hammers typically offer multiple operating modes, including drilling, hammer drilling, and hammer-only chiseling, providing versatility for various construction and renovation projects.
