Cordless 21V 4.0Ah Lithium Battery 100MM angle grinder

An angle grinder is a versatile power tool commonly used in construction, metalworking, and fabrication tasks. It consists of a motor-driven abrasive disc or wheel that rotates at high speeds to grind, cut, polish, or sand various materials such as metal, stone, concrete, and tiles.

Key components of an angle grinder include:

Motor: The electric motor provides the power to rotate the abrasive disc.

Disc/Wheel: This is the part of the grinder that comes into contact with the material being worked on. Discs come in various types for different tasks, such as cutting, grinding, sanding, or polishing.

Guard: A safety guard that covers the rotating disc to protect the user from debris and sparks.

Handle: An ergonomic handle for gripping and controlling the grinder during operation.

On/Off Switch: A switch to control the power supply to the motor.

Spindle Lock: A feature that allows for easy and quick changing of discs.

Adjustable Side Handle: Some models come with a side handle that can be adjusted for better control and comfort during use.

Angle grinders are available in different sizes, typically ranging from 4.5 inches to 9 inches in disc diameter. They can be powered by electricity, batteries, or compressed air. When using an angle grinder, it's essential to wear appropriate safety gear, including eye protection, gloves, and hearing protection, due to the high-speed rotation of the disc and the potential for sparks and debris. Additionally, following proper safety procedures and techniques is crucial to avoid accidents and injuries.
