A 21V cordless lithium polishing angle grinder is a handheld power tool used for various tasks, primarily for polishing and grinding surfaces. Here's a breakdown of what each part of the name means:

1. 21V: This refers to the voltage of the tool's battery. In cordless power tools, the voltage indicates the power and capacity of the battery. A 21V battery typically provides a moderate amount of power, suitable for light to medium-duty tasks.

2. Cordless: This means that the tool operates without a cord. It is powered by a rechargeable battery, which offers the advantage of portability and freedom of movement since you're not restricted by a power cord.

3. Lithium: This indicates the type of battery technology used in the tool. Lithium-ion (Li-ion) batteries are popular in cordless tools because they provide a good balance of power and runtime, have a longer life cycle, and are relatively lightweight.

4. Polishing: This tool is designed for polishing applications. Polishing involves smoothing and shining a surface, often using a polishing wheel or attachment and a suitable polishing compound.

5. Angle Grinder: An angle grinder is a versatile handheld power tool that uses a rotating abrasive disc or wheel to perform various tasks such as cutting, grinding, polishing, and sanding. The term "angle grinder" is commonly used for such tools.When you have a 21V cordless lithium polishing angle grinder, you can use it for tasks like polishing metals, grinding down rough surfaces, cutting through materials like metal or stone, and other related applications. It's a portable and convenient tool for DIY enthusiasts and professionals alike, allowing you to work in various locations without being tethered to a power source.
