Methods of Cutting a Copper Pipe

There are several effective methods for cutting copper pipe to get the job done.

Using a pipe cutter involves securing it around the pipe and tightening the handle while rotating to score and cut through the pipe.

For hacksaws, select a 32 TPI blade, securely clamp the pipe, and cut with smooth strokes. A reciprocating saw equipped with a metal blade can cut copper pipe in tight spots with steady motions.

Tubing cutters outfitted with copper cutting wheels are adjusted to the pipe size, tightened, and rotated to cut. Each method has its advantages and proper use leads to smooth, straight copper pipe cuts.

We can use a torch or drill to cut the copper pipes as well.

Here are the step-by-step instructions for each method:

Using a Pipe Cutter

A pipe cutter is the preferred method for making precise, straight cuts in copper pipes.

Secure the pipe cutter around the copper pipe by tightening the handle to clamp the cutting wheel in place.
Rotate the cutter around the pipe, tightening the handle slightly after each rotation. This will increasingly score a straight line around the circumference.
Continue tightening the handle and rotating until the cutting wheel fully penetrates and severs the pipe. Apply firm but gradual pressure.
Remove any burrs from the cut edge using a reaming tool or file to smooth out the end.

Using a Hacksaw

Hacksaws are a common tool for cutting copper pipe. Selecting the right blade is key – a 32 TPI blade will provide clean, efficient cuts. Securely clamping the pipe prevents movement while cutting.

Applying smooth, steady pressure at a 90-degree angle ensures straight cuts. Expect some burrs and filing/sanding is needed to smooth the cut edge. With the proper blade and technique, hacksaws are an effective way to cut copper pipe.

For situations where a pipe cutter won’t fit, a hacksaw can be used to cut copper pipes.

Select a hacksaw blade with 32 teeth per inch, which will provide a cleaner cut in copper.
Clamp the copper pipe securely in a vise to prevent movement while cutting.
Mark a straight cutting line around the full circumference using a permanent marker.
Position the hacksaw at the cutting line. Keep the blade perpendicular to the pipe.
Applying firm but controlled pressure, begin cutting through the pipe with smooth, steady motions.
After cutting, use a file or sandpaper to remove any burrs from the cut edge.

Using a Reciprocating Saw

For cutting copper pipe in tight spaces, a reciprocating saw is a handy power tool option. Using a metal cutting blade, the pipe can be cut by applying steady pressure with the blade.

The saw’s maneuverability allows for cutting in confined areas. Expect some burrs and filing/sanding to smooth and deburr the cut edge. With care and the right blade, a reciprocating saw cleanly cuts copper pipe in difficult locations.

For cutting copper pipes in tight spaces, a reciprocating saw provides more maneuverability.

Select an appropriate metal cutting blade for the reciprocating saw. Variable tooth blades work well.
Clamp or secure the copper pipe to prevent vibration while cutting.
Position the reciprocating saw blade at the marked cutting line.
Cut through the pipe applying smooth, steady pressure. Let the saw do the work.
Use a file to remove any burrs left on the cut edge.

Using a Tubing Cutter

A tubing cutter is a specialized tool for straight, precise cuts in copper pipe. Fitted with a copper cutting wheel, the cutter is adjusted to fit the pipe size.

As the handle is tightened and rotated around the pipe, it scores and cuts through efficiently. Tubing cutters are simple to use and make smooth cuts even in tight spaces. They are an effective go-to tool for cleanly cutting copper pipe.

Tubing cutters for PVC can also cut copper when fitted with a copper cutting wheel.

Adjust the tubing cutter size to fit the outside diameter of the copper pipe section.
Tighten the handle to clamp the cutting wheel in place around the pipe.
Rotate the cutter around the pipe, tightening further with each rotation to score the pipe.
Progressively tighten and rotate until the wheel cuts all the way through the pipe.
Smooth out any burrs on the cut edge with a reaming tool.

Using a Torch

Cutting copper pipe with a torch is a quick and effective method when done properly. For safe operation, always wear protective goggles and gloves since the torch flame can reach over 5,000°F. Work in a well-ventilated area to avoid inhaling fumes.

Using an oxy-acetylene torch kit allows precise control of the cutting flame. The pipe must be cleaned and secured horizontally to prevent accidents. Ignite the torch and adjust to a neutral flame before heating a small section of the pipe.

Slowly move the flame along the marked cut line, heating just ahead of the cut. When the pipe glows red, it can be separated with light pressure on the torch tip. Allow time to cool and use a wire brush and emery cloth to smooth the cut edge. With caution, a torch provides fast, clean cuts in copper pipe.

Proper protective gear and technique prevent injuries when handling extreme heat. Torch cutting is an advanced but efficient method for experienced DIYers working with copper plumbing.

Cutting copper pipe with a torch is an effective method that produces clean, precise cuts quickly. Follow these steps for the best results:

Materials Needed

Oxy-acetylene torch kit with regulators, hoses, and tips
Copper pipe – should be clean and free of debris
Pipe securing vise or clamps
