Plumbing Tips on Cutting Cast Iron Pipe

Cutting Iron Pipe the Easy Way

• To cut iron pipe properly, you need to learn its characteristics. Iron pipe is brittle, which means it shatters easily. Similar to glass, it breaks easier than it cuts. So, actually cutting through the pipe is not recommended. In fact, you should plan on breaking through the pipe rather than sawing through it. A few special tools will help when you cut any type of iron pipe.

Saws and Grinders

• Sawing through iron pipe with a saw, grinder or similar tool is not recommended. Sometimes. however, this is the only option. If you have to use a cutting tool, do not use a pipe saw. Because of the density and hardness of the iron, it will only wear down the teeth on the blades. If you have to cut the iron pipe with anything, due to its position and accessibility, use a grinder with a metal cutting disc. A diamond or carbide disc is the most suitable option in almost every case. Always wear eye protection when you handle these tools.

Chisels

• A chisel is another option when cutting iron pipe. Chisels break the brittle metal apart, effectively cutting through without sawing the metal. Use a cold chisel, which is specifically designed for iron. Strike the chisel with a ball peen hammer and cut across the width of the pipe. Also, use protection whenever using this method to cut iron pipe because the metal filings and shavings will fly off the pipe as you strike it.

Snap Cutters

• One of the most effective methods for cutting iron pipe into many pieces is the snap cutter. This tool bites into the iron with several small disc cutters on a chain. The chain is connected to a set of lever handles, which the user presses together to increase the tension on the chain. You probably don't have one of these tools, so renting one from a tool rental company is necessary.
