First, make sure the water is off. Turn the main valve to your house. Then open a faucet somewhere low (like a basement sink) to drain the line. Trust me, you don’t want a sudden shower of rusty water in your face.
Next, slide your mini cutter onto the pipe. Tighten the knob until the wheel bites into the copper. Then rotate the whole cutter around the pipe, tightening the knob a quarter turn every few rotations. You’ll feel and hear it click as the pipe scores and snaps.
If you’re using a hacksaw, wrap the pipe in a strip of masking tape as a cutting guide. Saw with short, slow strokes. You’re not chopping wood; you’re persuading the metal. A clean cut now saves you a headache later.
Once it’s cut, clean the pipe’s end with emery cloth (sandpaper for pipes). Wipe it shiny. Now you can solder, use a compression fitting, or even push-fit connectors—all without swearing at a wall that’s in the way.
The Splurge That’s Worth It
If you do this kind of work more than once a year, buy a rotary tool with a cut-off wheel. It’s like a mini buzzsaw. You can slice copper in tight spaces in seconds. Wear safety glasses, because those little metal bits will fly like glitter at a punk show.

But if you’re a “once every five years” kinda person, a ten-dollar mini cutter from the hardware store is your best friend. It sits in your toolbox for years, waiting to save you on a random Saturday. That’s a good kind of loyalty.
