A clean, square cut is the difference between a joint that seals and one that leaks. A hacksaw crushes and burrs the pipe; a proper cutter scores it cleanly. The catch is that copper, PEX, and PVC each want a different cutter — using the wrong one is how you get bad cuts and bad joints.
Here’s what I actually carry for each material, plus a cordless option if you cut copper all day.
Best for Copper: RIDGID Tubing Cutter
RIDGID’s tubing cutter is the plumber’s standard for copper. The cutting wheel scores a clean, round cut you can deburr and solder or push-fit with confidence, and the build lasts decades. Get the mid-size for 1/8″ to 1-1/8″ tubing, and a mini cutter for tight spots behind fixtures.
Best for PEX: Ratcheting PEX Pipe Cutter
PEX needs a clean, square cut so the fitting seals — a ratcheting PEX cutter shears the tubing in one squeeze without crushing it. They’re inexpensive and make crimp and push-fit connections far more reliable than hacking PEX with a utility knife. A must if you’re running any PEX.
Best Cordless: Milwaukee M12 Copper Tube Cutter
If you cut a lot of copper — repipes, additions — the M12 cordless cutter spins around the pipe and cuts in about three seconds, even in tight quarters where you can’t swing a manual cutter. It’s a pro tool at a pro price, but for volume copper work it’s a back-saver.
How to Cut Pipe Cleanly
- Match the cutter to the material: tubing cutter for copper, ratcheting shear for PEX, and a fine-tooth cutter or wheel cutter for PVC/CPVC.
- For copper: clamp the cutter on the pipe, tighten lightly, and rotate around the pipe, snugging the knob a quarter turn each pass until it parts.
- Always deburr copper cuts inside and out with a deburring tool — burrs cause turbulence, noise, and weak solder joints.
- For PEX: square the tubing in the jaws and squeeze in one motion for a clean, perpendicular cut.
- Dry-fit the connection before sealing to confirm the cut is square and the pipe seats fully into the fitting.
FAQ
Can I use one pipe cutter for copper, PEX, and PVC?
Not well. A wheel-style tubing cutter is made for copper and other metals; PEX needs a ratcheting shear that won’t crush it; PVC is best cut with a ratcheting plastic cutter or fine-tooth saw. Using a copper wheel cutter on PEX deforms the tubing and causes leaks. Use the right tool per material.
Do I need to deburr after cutting copper pipe?
Yes. Cutting leaves a raised burr inside and outside the pipe. The inside burr restricts flow and creates turbulence (and noise); the outside burr keeps the pipe from seating fully in a fitting. A quick pass with a deburring tool fixes both and is essential for a good solder or push-fit joint.
Is a cordless pipe cutter worth it?
For a homeowner doing the occasional repair, no — a manual tubing cutter is cheap and works fine. For anyone cutting copper in volume or in tight spaces where you can’t rotate a manual cutter, a cordless cutter like the Milwaukee M12 saves real time and effort.
Bottom Line
There’s no single best pipe cutter — there’s the right one for your material. Get a RIDGID tubing cutter for copper, a ratcheting shear for PEX, and the right cutter for PVC. Cutting copper all day? The cordless M12 earns its keep. Whatever you use, cut square and deburr — that’s what makes joints seal.
