How does a Rotary Hammer Works

 

 

A sds rotary hammer works by combining the actions of rotation and hammering to efficiently drill through tough materials like concrete, stone, or masonry. Here's how it operates:

 

 

 

 

**Rotation:** The electric rotary hammer features a powerful motor that drives a spinning motion to rotate the drill bit. This rotation helps to break through the surface of the material being drilled.

 

 

 

 

 

 

 **Hammering Action:** In addition to rotation, the SDS rotary hammer also delivers a hammering action. This is achieved through a piston mechanism inside the tool. As the motor rotates, it drives the piston forward and backward rapidly, creating a pounding motion.

**Impact Energy:** The pounding motion of the piston generates high impact energy, which is transmitted through the drill bit to the surface being drilled. This impact energy helps to break up the material, allowing the drill bit to penetrate more effectively.

 

 

 

 

 

 

 

 **Drilling Depth Control:** Most SDS rotary hammers allow users to adjust the drilling depth by setting the depth stop or using depth control features. This ensures precise drilling and prevents over-drilling.

 

 

 

**Versatility:** Electric Rotary hammers often come with multiple operating modes, including drilling-only mode, hammer-drilling mode, and chiseling mode. This versatility allows users to perform various tasks such as drilling holes, hammer drilling for tough materials, and chiseling for demolition or surface preparation.

 

 

                                                                 

 

 

 

 

Overall, the combination of rotation and hammering action in a SDS rotary hammer makes it a highly efficient and powerful tool for drilling through hard materials, making it indispensable in construction, renovation, and demolition projects.
