Angle Grinder

An angle grinder, also known as a cut-off grinder or "Flex," is a versatile power tool used for cutting, grinding, polishing, and rust removal on materials such as metal, stone, and concrete. It is indispensable in many craft, industrial, and DIY applications. An angle grinder consists of an electric motor that drives a rotating grinding or cutting disc mounted at an angle to the motor axis.

Types of Angle Grinders

Small Angle Grinders: Typically equipped with discs ranging from 115 to 125 mm, ideal for lighter tasks and precise work.
Large Angle Grinders: Feature discs from 180 to 230 mm, suitable for heavier tasks and larger material volumes.
Cordless Angle Grinders: Battery-powered models offering mobility and flexibility, though often less powerful than corded versions.
Pneumatic Angle Grinders: Powered by compressed air, ideal for industrial applications requiring high performance and endurance.

Applications of Angle Grinders

Metalworking: Cutting, grinding, and polishing metal parts and surfaces.
Construction: Cutting and grinding concrete, stone, and bricks during building and renovation work.
Vehicle Repair: Removing rust and old paint layers, cutting body parts.
Woodworking: Sanding and polishing wood surfaces, removing old paints and finishes.
Home and Garden: Cutting and grinding various materials for DIY projects.
