Pipe Cutters
Plastic pipe cutter choices for clean, square cuts on waste, conduit and plastic tube without crushing or burrs.
When you're trimming waste pipe under a sink or knocking up a run of conduit, a decent plastic pipe cutter saves you fighting ragged ends and leaks. Pick the right jaw size and a ratchet pipe cutter for thicker PVC, and your fittings go on first time.
What Are Plastic Pipe Cutters Used For?
- Cutting waste pipe cutter sizes cleanly under sinks and in service voids so solvent weld and push-fit joints seat properly without a chewed edge.
- Trimming plastic conduit on first fix without splitting it, especially when you need repeatable, square cuts for couplers and saddles.
- Working on tight refurbs where a saw is awkward, using a ratchet pipe cutter to get through thicker wall PVC pipe without crushing the tube.
- Batch cutting common sizes like a 10mm pipe cutter up to 35mm pipe cutter ranges when you are making up multiple runs and want consistent lengths.
- Keeping installs tidy with plastic pipe slices that leave less deburr work, so you are not scraping swarf out of the pipe before fitting.
Choosing the Right Plastic Pipe Cutter
Keep it simple: match the cutter to the pipe size and wall thickness, or you will either struggle through the cut or crush the pipe.
1. Size range and what you actually cut
If you are mostly on small tube, a plastic pipe cutter 15mm or 22 mm pipe cutter style is quicker and easier to control. If you are on waste and soil, look at larger jaws like a 35mm pipe cutter or 42mm plastic pipe cutter so you are not forcing it and leaving a wonky end.
2. Ratchet vs straight action
If you are cutting thicker PVC, a ratchet pipe cutter gives you steady pressure and a cleaner finish without cracking. If it is thin wall conduit and light plastic, a simpler straight action cutter is faster for quick trims.
3. Blade access and replaceability
If you are using it daily, make sure the blade can be changed and the mechanism is easy to clean out, because grit and swarf will start dragging and you will feel it in the cut straight away.
4. Pipe type and finish required
For waste pipe cutter jobs and solvent weld, you want a dead square cut and minimal burr so the joint seals properly. For conduit, prioritise a cutter that does not oval the tube, or you will fight the couplers and saddles.
Who Uses Plastic Pipe Cutters on Site?
- Plumbers and heating engineers who want fast, square cuts on plastic pipe so fittings do not weep and the job looks sharp at second fix.
- Sparks and fire and security installers using a plastic conduit cutter to keep conduit runs neat, especially when cutting in corners and tight risers.
- Maintenance teams doing reactive repairs who need pipe cutters that work one handed in cupboards, lofts, and awkward plant rooms.
- Site fitters and kitchen and bathroom installers who keep a pipe slicer in the bag for quick trims without dragging a saw and file into finished areas.
How Plastic Pipe Cutters Work for You
A plastic pipe cutter is basically a controlled shear cut, designed to keep the pipe round and the end square so it fits properly. The type of action matters more than people think.
1. Ratchet pipe cutters (steady pressure)
The ratchet advances the blade in small steps, which stops you having to muscle through thick wall PVC. On site that means fewer cracked cuts and less time cleaning up ragged edges before you fit.
2. Anvil and jaw support (keeps it square)
The jaw supports the pipe while the blade comes through, so the tube does not flex like it can with a saw. The result is a cleaner, squarer end that pushes into fittings without shaving plastic into the line.
3. Blade sharpness (finish and effort)
A sharp blade is the difference between a clean plastic pipe slice and a crushed, burred end. If the cutter starts leaving a lip, it is either blunt or full of grit, and it is time to clean it out or swap the blade.
Plastic Pipe Cutter Accessories That Save Time
A couple of small add ons keep cuts clean and stop you getting caught mid job with a blunt blade or the wrong size cutter.
1. Replacement blades
Keep a spare blade in the van, because a dull cutter will start crushing PVC and leaving burrs that ruin push fit and solvent weld joints, especially on thicker waste pipe.
2. Pipe cutter set or pipe slice set
If you bounce between sizes, a pipe cutter set stops you trying to make a 22mm pipe cutter do a larger job, or dragging a big cutter onto small tube where it is harder to keep the cut square.
3. Deburring tool or reamer
Even with good plastic pipe cutters, a quick deburr is what stops plastic swarf catching in the fitting and gives you a cleaner seat, especially when you are cutting conduit and pushing through couplers.
4. Measuring and marking kit
A tape and a fine marker sounds basic, but it is what keeps multiple cuts consistent when you are batching lengths, and it saves you wasting pipe because you guessed the cut line.

Plastic Pipe Cutter FAQs
What is the best plastic pipe cutter for professional use?
The best plastic pipe cutter is the one that matches your pipe size and has a solid, non flexing jaw with a sharp, replaceable blade. If you are cutting thicker wall PVC or larger waste, a ratchet pipe cutter is usually the right call because it cuts steadily without cracking the pipe.
How do I choose the right plastic pipe cutter?
Start with the diameter you actually see on the job, like 15mm and 22mm for smaller tube or bigger jaws for waste. Then think about wall thickness, because thicker PVC is where ratchet pipe cutters earn their keep. If you are constantly swapping sizes, a pipe cutter set stops you forcing the wrong tool and leaving poor cuts.
What are the key features to look for in a plastic pipe cutter?
Look for a blade that stays sharp and can be replaced, a jaw that supports the pipe so it does not oval, and a mechanism that does not bind up when it gets dusty. A positive lock or latch helps in the tool bag, and a ratchet action is worth it when you are cutting thicker PVC or larger diameter plastic.
Will a plastic pipe cutter work on copper pipe as well?
No, do not rely on it for copper. Plastic cutters are designed to shear plastic, and copper needs a proper tube cutter or copper cutter to avoid damaging the tool and flattening the pipe. If you do both, keep separate cutters in the bag.
Why is my cut end crushed or out of square?
That is nearly always one of three things: the cutter is too small for the pipe, the blade is blunt, or the pipe is not seated properly in the jaw. Step up to the correct size range, clean out the mechanism, and change the blade if it is dragging, because forcing it is what cracks PVC and ruins fittings.
