Bosch Rotary Hammer (720-1700 W)

A rotary hammer is a powerful and versatile tool primarily used in construction and renovation projects for drilling holes in tough materials like concrete, masonry, stone, and brick. Unlike traditional drills, which operate by rotating the drill bit, rotary hammers combine rotary motion with a pounding or hammering action, making them more efficient at drilling through hard surfaces.

The main components of a rotary hammer include a motor, a hammering mechanism, a chuck, and a handle. The motor provides the rotary motion, while the hammering mechanism generates the percussive force required to break through hard materials. This mechanism typically involves a piston that moves back and forth inside a cylinder, striking the back of the drill bit with considerable force.

Rotary hammers are available in various sizes and power ratings, ranging from small handheld models suitable for light-duty work to larger, more powerful machines designed for heavy-duty industrial applications. They may be corded or cordless, with cordless models offering greater mobility but usually at the expense of power compared to their corded counterparts.

One of the key features of rotary hammers is their ability to switch between drilling modes. In addition to standard drilling mode, rotary hammers often include settings for hammer drilling and chiseling. Hammer drilling mode combines rotation with hammering action, while chiseling mode allows the tool to function like a mini jackhammer for tasks such as breaking up concrete or removing tiles.
