Is a Hacksaw a Good Choice for Cutting Copper Pipe?
Yes, a hacksaw is a good choice for cutting copper pipe, but it has some drawbacks. Hacksaws are readily available, inexpensive, and easy to use, making them a popular option for DIYers and plumbers. However, cutting copper with a hacksaw requires effort and precision. Usually, when you think about what a hacksaw is, it’s associated with woodworking tools. However, to cut copper pipe, the blade must be fine-toothed to ensure a clean cut, and the sawing motion should be steady to avoid bending or deforming the pipe.
One disadvantage of using a hacksaw is that it can leave rough or uneven edges, which may require additional filing or sanding to smooth out. This is important when making plumbing connections to ensure a tight fit and prevent leaks.
For a quicker and cleaner cut, a tubing cutter is often a better choice, as it provides a precise, burr-free edge. However, if a hacksaw is the only tool available, it can still get the job done effectively with proper technique and post-cut finishing.
Pros of Using a Hacksaw
Using a hacksaw to cut copper pipe has several advantages:
- Accessibility – Most people already have a hacksaw in their toolbox. For example, you can get this 12in. High-Tension Hacksaw Frame with 24 TPI Bi-metal Blade for about $10.
- Cost-effective – No need to buy a special pipe cutter if you already own a hacksaw.
- Versatile – Works on different pipe sizes and other materials beyond copper.
Cons of Using a Hacksaw
However, there are some drawbacks to using a hacksaw:
- Requires more effort – Compared to pipe cutters, a hacksaw needs more manual effort and patience.
- Less precision – It can be difficult to get a perfectly straight cut.
- Creates rough edges – The cut may leave burrs that need additional finishing.
- Not ideal for installed pipes – Cutting pipes already in place can be tricky with a hacksaw.
How to Cut Copper Pipe with a Hacksaw: Step-by-Step Guide
If you decide to use a hacksaw, follow these steps for the best results:
1. Gather Your Tools and Materials
You’ll need:
- A hacksaw (preferably with a fine-tooth blade)
- A vise or clamps (to secure the pipe)
- A measuring tape and marker like RevMark Bright Series Industrial Markers which are used to draw and write on pipes.
- Safety goggles and utility gloves like the HANDLANDY Work Gloves for Men & Women
- A metal file or sandpaper (for smoothing the edges)
2. Mark the Cutting Line
Use a measuring tape to determine where you need to cut, then mark the pipe with a permanent marker or a pencil. This will help you stay on track while sawing.
3. Secure the Pipe
Place the pipe in a vise or clamp it to a stable surface to prevent movement. If you’re cutting a pipe that’s already installed, make sure you have enough space to move the hacksaw back and forth.
4. Use Steady, Even Strokes
Position the hacksaw blade on the marked line and start cutting with gentle, controlled strokes. Let the blade do the work—don’t force it. Too much pressure can cause uneven cuts.
5. Smooth the Edges
After cutting, you’ll likely have rough edges or burrs. Use a metal file, sandpaper, or a deburring tool to smooth the edges. This prevents sharp burrs from damaging pipe fittings or seals.
When a Hacksaw is NOT the Best Option
While a hacksaw is useful, there are situations where it may not be the best tool:
- Tight spaces – If the pipe is installed in a tight spot, a pipe cutter or rotary tool may work better.
- Multiple cuts – If you need to make many precise cuts, a pipe cutter will be faster and cleaner.
- Professional projects – If you’re working on a professional plumbing installation, a specialized tool like a pipe cutter is preferred.
Alternative Tools for Cutting Copper Pipe
1. Tube Cutter (Best Alternative for Precision)
A tube cutter is specifically designed for cutting copper pipes. It provides clean, precise cuts with minimal effort.
- How it works: You clamp the tool around the pipe, tighten it, and rotate it until the pipe is cut through.
- Best for: Plumbing projects where accuracy is important.
2. Rotary Tool (Good for Small Cuts in Tight Spaces)
A rotary tool with a cutting wheel can also cut copper pipes, especially when working in confined spaces.
- How it works: You attach a metal-cutting disc and slowly grind through the pipe.
- Best for: Quick cuts in tight or awkward areas.
3. Reciprocating Saw (Fast but Requires Precision)
For larger projects, a reciprocating saw can be used, but it requires a steady hand to avoid jagged cuts.
- How it works: A power saw with a metal-cutting blade quickly slices through the pipe.
- Best for: Cutting through multiple pipes quickly.
Safety Tips When Cutting Copper Pipe
- Wear safety gear – Always use safety goggles and gloves to protect against metal shavings and sharp edges.
- Clamp the pipe securely – Prevent movement to ensure a clean, safe cut.
- Use a sharp blade – A dull hacksaw blade makes cutting harder and increases the risk of uneven edges.
- Clean up burrs – Smooth out the cut edges to prevent injury and ensure a proper fit with fittings.
Final Thoughts: Is a Hacksaw the Right Tool for the Job?
Yes, you can use a hacksaw to cut copper pipe, but it’s not always the easiest or most efficient option. If you only need to make a few cuts and don’t have a pipe cutter, a hacksaw can get the job done. However, for precise, clean cuts—especially in professional plumbing work—a pipe cutter is a better choice.
By following the right techniques and safety precautions, you can successfully cut copper pipes with a hacksaw while ensuring a clean, functional result.
