Best Plastic Pipe Cutters for Plumbers: PVC, PEX and Drain Tubing
RIDGID RC-1625 is the manual ratchet starting point for supported smaller plastic pipe. RC-2375 provides more diameter capacity; Milwaukee 2470-20 suits repeated supported cuts. KNIPEX 90 25 20 is another cutting format, while BiX targets thin-wall plastic and sealing-sleeve jobs.

Product image: Acme Tools. Check the listing for included accessories.
PVC, CPVC, PEX and thin-wall drain tubing are not one uniform material. Check outside diameter, permitted wall thickness and pipe condition. BiX is deliberately a specialist alternative, not a substitute for a heavy-wall PVC shear.
HOW TO CHOOSE
What matters for the work
Match blade and material
The tool’s approved pipe materials and wall thickness matter more than a large maximum opening. Brittle, old or cold plastic may behave differently from a new tube. Check manufacturer instructions before assuming every plastic line can be cut with a shear.
Diameter and straightness
Capacity is a limit for the specified workpiece dimension, not a promise about any nominal pipe label. The work should fit properly in the cutting support. Squareness and preparation requirements are determined by the connection system.
Manual versus powered
A ratchet cutter avoids battery dependence and fits a compact repair kit. A cordless shear is more relevant to repeated installation cuts. Compare replacement blades and the complete battery kit before paying for a powered format.

RC-1625 Ratcheting Plastic Pipe Cutter (23498)
Best for: A compact service kit for supported smaller plastic tubing.
RC-1625 is a manual ratcheting shear with a published outside-diameter limit of 1-5/8 inches. Its place is in repair and installation work where the specified plastic fits the blade and supporting jaw.
Choose it after checking material, wall and actual diameter. It provides a battery-free cutting role, but blade condition and correct workpiece support remain important. RC-2375 is the size alternative; a powered shear is a different purchase decision for repeated cuts.

RC-2375 Ratcheting Plastic Pipe Cutter (30088)
Best for: Supported plastic pipe outside the smaller RC-1625 range.
The RC-2375 provides a larger ratcheting cutting envelope. It is the comparison to make when the workpiece genuinely exceeds the smaller cutter’s outside-diameter range.
Verify the actual pipe dimension and material before choosing it. A larger tool also needs more room in the work area and bag. Its capacity does not establish suitability for damaged or brittle pipe; choose the cutting method required by the material and fitting manufacturer.

2470-20 M12 Plastic Pipe Shear
Best for: M12 users making repeated supported plastic-pipe cuts.
The M12 2470-20 changes supported plastic cutting from a manual ratchet task to a battery-powered shear. Milwaukee lists several compatible materials, but the exact size and material instructions still govern the job.
Buy it when the cutting volume and existing M12 system justify the extra tool. Compare blade replacements, head access and complete battery cost. The tool-only number does not imply a battery is included, and the shear should not be treated as a universal pipe-cutting machine.

90 25 20 Plastic Pipe Cutter
Best for: Buyers comparing a KNIPEX plastic-pipe cutter with RIDGID ratchet formats.
KNIPEX 90 25 20 is a dedicated plastic-pipe cutter rather than a copper wheel cutter. Its supporting geometry and replaceable blade are the relevant details to check for the pipe you install.
Select it from its published application range, not from the appearance of a similarly sized shear. Confirm the exact number and spare blade. For thin-wall tubing, compare BiX; for repeated supported installation cuts, compare the M12 shear rather than assuming all three cover the same work.

90 22 10 BiX Plastic Pipe Cutter
Best for: Specified thin-wall plastic drain tubing and sealing-sleeve work.
BiX is a compact specialist for thin-wall plastic tubing and specified sleeve tasks. That is a distinct role from the ratcheting shears in this guide, even though all are sold as plastic-pipe tools.
Choose it because its documented wall and material range matches your job. It should not become the only plastic cutter in a kit that handles thicker pressure pipe. Check the blade position, permitted tube size and preparation required for the intended connection before ordering.
Only when the manufacturer lists the PEX material and diameter for that exact cutter. Different plastic materials and walls need different cutting support.
Why does a plastic cutter crack old pipe?
Brittleness, temperature, blade condition and unsuitable cutting geometry can contribute. Stop if the material is not cutting as the instructions require; do not assume more force is the solution.
What is the difference between RC-1625 and RC-2375?
They have different maximum outside-diameter capacities. Choose by the actual pipe and the clearance for the tool, not by the nominal trade size alone.
Can BiX cut thick PVC pressure pipe?
BiX is intended for specified thin-wall plastic tubes and sealing sleeves. It should not be presented as a universal replacement for a ratcheting pressure-pipe cutter.
