What power tool is used to cut the board round

To cut a board into a round shape, you would typically use a power tool called a "jigsaw" or a "band saw." These tools are designed for making curved and intricate cuts in various materials, including wood.

1. Jigsaw: A jigsaw is a versatile handheld power tool that uses a reciprocating blade to cut curves, circles, and other irregular shapes in wood and other materials. It's an excellent choice for cutting boards into round shapes, as it allows for greater control and precision. To make a round cut, you would drill a starter hole in the center of the board, insert the jigsaw blade, and then follow the desired circular pattern.

2. Band Saw: A band saw is a stationary power tool that uses a continuous loop of a blade stretched between two wheels. It's ideal for making curved and circular cuts in wood. To use a band saw, you would adjust the blade guide and table to the desired angle and then feed the board into the blade, following the circular pattern.

When using either of these tools to cut a board into a round shape, it's essential to secure the board firmly, wear appropriate safety gear (safety glasses and ear protection), and follow all safety instructions provided in the tool's user manual. Additionally, you can use templates or guides to help you achieve precise circular cuts.
