A rotary hammer is an electric tool designed for drilling holes in concrete, brick, stone, and other hard materials. Here are the key characteristics and functions of rotary hammers:

Motor and Power Source: Rotary hammers typically feature a powerful electric motor and can be corded (connected to an electrical outlet) or cordless (powered by a rechargeable battery). They provide the extra power required for drilling into hard materials.

Operating Modes: One of the key features of rotary hammers is their ability to switch between modes for regular drilling, hammer drilling, and chiseling. The hammer drilling mode enables fast and efficient drilling in concrete and stone.

Specialized Drill Bits: Rotary hammers use special drill bits with carbide tips designed for working with hard materials.

Depth Adjustment: Many rotary hammers have a depth adjustment feature, allowing users to control the depth of the holes they drill.

Applications: Rotary hammers are widely used in construction and renovation. They are employed for drilling holes for anchor bolts, fasteners, electrical conduits, and other tasks related to working with concrete and masonry.

Vibration Damping and User Comfort: Many modern rotary hammers are equipped with vibration damping systems and comfortable handles to reduce vibrations and enhance user comfort.

Rotary hammers are essential tools for builders and renovators, enabling efficient work with hard materials and completing drilling and chiseling tasks with minimal effort.
