A power rotary hammer is designed for heavy-duty drilling and chiseling in materials such as concrete, stone, and masonry. It uses a combination of rotary and hammering action to penetrate hard surfaces more efficiently than standard drills.

The tool typically consists of a motor, piston mechanism, and rotating hammer bit. Variable speed settings and adjustable impact force allow users to adapt the tool for different applications, from drilling anchor holes to light demolition tasks.

Rotary hammers can be corded or battery-powered, providing options for stationary or mobile work. Ergonomic handles and vibration reduction systems improve comfort during extended use. Safety features, including trigger locks and overload protection, help prevent accidents.

This tool is commonly used in construction, renovation, and industrial projects. Regular maintenance, such as cleaning dust and checking mechanical parts, ensures long-term reliability.

By combining impact and rotation, power rotary hammers provide efficient and controlled performance, supporting demanding tasks in hard materials while improving work efficiency.
