If you need to use black iron pipe for a plumbing or other do-it-yourself project, you will need to know how to properly cut the pipe to lengths you need to do the job. Cutting black iron pipe is an easy DIY task, and this simple guide will show you how. Let's get started.

1. Cut the Pipe with a Hack Saw

To cut the pipe with a hack saw, place the pipe in a vise and then use a hack saw to cut across the marking line for the measurement. With this method, you may need two or more blades for the saw depending on the diameter of the pipe.

2. Cut Iron Pipe with a Hammer and Chisel

This is a very good way to cut iron pipe. Create a marking line and use the hammer and chisel to score the line around the pipe. Score the pipe by striking the back of the chisel with the hammer. After several strikes, the iron pipe should snap off at the marking line point. Use an adjustable wrench and hammer to remove any jagged pieces.

3. Cut Pipe with a Snap Cutter

This is the preferred method of professionals for cutting iron pipe. Wrap the chain on the snap cutter on the pipe around the point where you want to make your cut. Then, use the ratchet on the device to tighten the chain. When the chain is tight enough, the pipe will snap off at the cut mark.
