A reciprocating saw, also known as a Sawzall, is a type of power tool that is commonly used for demolition work and other applications where it is necessary to cut through materials such as wood, metal or plastic.
The reciprocating saw gets its name from the fact that the blade moves back and forth in a reciprocal motion, similar to the motion of a hand saw. However, unlike a hand saw, which requires the user to push and pull the blade in order to make a cut, a reciprocating saw uses an electric motor to power the blade. This makes it much easier to use and far more efficient than a hand saw.
There are two main types of reciprocating saw: corded and cordless. Corded models are powered by an electrical outlet, while cordless models run on battery power. Both types have their advantages and disadvantages. Corded models tend to be more powerful but they are also tethered to an electrical outlet, which can be inconvenient. Cordless models offer greater portability but they may not have as much power as their corded counterparts.
When choosing a reciprocating saw, it is important to consider what you will be using it for and what features are most important to you. If you need a powerful tool for heavy-duty applications, then a corded model might be the best option. If you need something that is more portable so that you can take it with you on job sites or around the house, then a cordless model might be better suited for your needs.
