Question: 1 / 400

When cutting a pipe, how much should the cutting shell be turned with each turn of the pipe?

1/2 revolution

1 full revolution

When cutting a pipe using a pipe cutting tool, it is essential to ensure a clean and efficient cut. Turning the cutting shell by one full revolution with each turn of the pipe allows the cutting wheel to score the pipe evenly around its circumference. This approach helps achieve a smooth cut and prevents the risk of crushing or deforming the pipe, which can occur if the cutting wheel is not properly aligned or if the shell is turned too much.

The one full revolution provides a consistent application of pressure, ensuring that the cutting wheel makes contact with the pipe thoroughly and evenly. It also helps the user maintain control during the cutting process, which is crucial for safely cutting various types of pipes. Hence, this technique promotes precision, leading to a more uniform cut without compromising the integrity of the material being worked on.
