An angle grinder is a handheld power tool used for cutting, grinding, and polishing various materials, including metal, stone, concrete, and tile. It consists of a motor that drives a rotating abrasive disc, which can be a cutting disc, grinding wheel, or polishing pad. Angle grinders are versatile tools used in construction, metalworking, automotive repair, and DIY projects for tasks like cutting pipes, removing rust, and shaping metal.
The angle grinder has evolved from earlier grinding and cutting tools. With the development of electric motors and abrasive technology, angle grinders became more compact and powerful. Initially, they were used mainly in industrial settings, but over time, they have become widely available for both professional and home use. Their versatility and ease of use have made them essential tools in many workshops and construction sites.
The main purpose of an angle grinder is to perform cutting, grinding, and polishing tasks efficiently. It can cut through metal rods, pipes, and structural elements, grind down welds, remove excess material, and smooth surfaces. The angle grinder's ability to use different types of abrasive discs makes it suitable for a wide range of materials and finishing tasks, saving time and effort compared to manual methods.
The angle grinder operates by using an electric motor to rotate the abrasive disc at high speeds. The motor converts electrical energy into rotational motion, which is transferred to the disc through a spindle. The high-speed rotation of the disc enables it to cut, grind, or polish the material. Depending on the type of disc used, the tool can perform different tasks. For example, a cutting disc uses its sharp edges to cut through materials, while a grinding wheel grinds away material through abrasion, and a polishing pad uses abrasives to smooth and shine surfaces.
