How to Cut Copper Tubing: Tools and Techniques

When it comes to making precise and clean cuts on copper tubing or pipe, there are several methods and tools available to achieve the best results. This article explores the various options, from simple metal saws to specialized tubing cutters, and how to use them effectively.

Choosing the Right Cutting Tool

For frequent cutting of copper tubing, a pipe cutter is the most efficient and reliable tool. These cutters typically consist of a rotating handle and a cutting wheel designed to apply pressure as they rotate around the tubing, resulting in a clean, square cut with a rounded edge on the outside.

Using a Pipe Cutter

When using a pipe cutter, follow these steps:

Ensure you have the correct size cutter for the specific diameter of the copper tubing. Position the cutter snugly around the tubing. The cutting wheel should be in contact with the metal. Apply pressure to the rotating handle, turning it slowly to apply even pressure. This will gradually cut through the tubing until it snaps off cleanly. Once the cut is made, you may need to smooth out the inner edge using a tubing reamer or sandpaper to remove any burrs.

Alternative Cutting Methods

If you only need to make a single cut, a metal saw, such as a Jigsaw or a Hacksaw, can be effective, though it requires more skill and care.

Metal Saw:
Insert a metal cutting blade into the saw, and carefully align it along the mark where you want to cut. Make a series of back-and-forth movements to gradually cut through the tubing. This method is more time-consuming and can produce a less clean cut compared to a pipe cutter.

Hacksaw:
Use a hacksaw blade with a fine tooth, and make a series of small, controlled cuts. Ensure you apply steady pressure to maintain a straight cut. After cutting, use a tubing reamer to smooth out the inner edge.

Using a Sawsall for Copper Tubing

While a sawsall with a metal cutting blade can effectively cut copper tubing, it is not without drawbacks. The blade will produce small copper shavings, creating a mess that can be difficult to clean up. Additionally, the use of a sawsall can be less precise and may result in a dented or uneven cut if not handled carefully.

Advantages and Disadvantages

Advantages: Faster cutting and less manual effort than using a pipe cutter. Disadvantages: Creates a mess due to small copper shavings, less precise cuts, and potential damage to the tubing.

Conclusion

While a pipe cutter is the most straightforward and professional tool for cutting copper tubing, a metal saw or even a Hacksaw can be used for single cuts. A sawsall offers a quick solution but at the cost of precision and cleanliness. Regardless of the tool used, always ensure proper safety measures are in place, such as using protective eyewear and gloves, to prevent injury.
