Angle grinder. An angle grinder, also known as a side grinder or disc grinder, is a handheld power tool used for grinding (abrasive cutting) and polishing.Although developed originally as tools for rigid abrasive discs, the availability of an interchangeable power source has encouraged their use with a wide variety of cutters and attachments.
Die grinder, which is a high-speed hand-held rotary tool with a small diameter grinding bit. They are typically air-driven (using compressed air), but can be driven with a small electric motor directly or via a flexible shaft. Angle grinder, another handheld power tool, often used in fabrication and construction work.

Their initial product was the MS6 hand grinder, which featured an electric motor with an attached flexible shaft. By the late 1920s, the company replaced the flexible shaft with an angular gearbox. In 1935, Ackermann & Schmitt introduced the first low-speed angle grinder, followed by the launch of the first high-speed grinder in 1954. [6]
Grinding is a subset of cutting, as grinding is a true metal-cutting process. Each grain of abrasive functions as a microscopic single-point cutting edge (although of high negative rake angle), and shears a tiny chip that is analogous to what would conventionally be called a "cut" chip (turning, milling, drilling, tapping, etc.) [citation needed].
