Where RC-1625 fits a repair kit
The RC-1625 is the manual ratcheting option around which to build this comparison. RIDGID lists an outside-diameter range from 1/8 to 1-5/8 inches. That range is useful for selecting a candidate, but the pipe material and wall must also fall within the tool instructions. It is a compact way to add supported plastic cutting without committing to a battery-powered shear.
The larger cutter solves a size problem, not every cut problem
RC-2375 increases the diameter envelope, but it does not make material compatibility irrelevant. If a pipe is brittle or the connection calls for a different cutting and preparation method, a larger jaw is not the answer. Compare the true outside diameter, cutting support and access. For some jobs a saw or a different cutter will be the appropriate choice; this buying guide is not a complete material-processing procedure.
When a cordless shear becomes worth considering
Milwaukee 2470-20 is the relevant alternative when repeated supported plastic cuts make a powered tool worthwhile. Compare the required battery and the space around the workpiece, not just the tool body in a photograph. KNIPEX offers other manual formats, including BiX for thin-wall work. The point of this shortlist is to explain those boundaries so a buyer does not purchase a specialist cutter for an incompatible pipe.

QUESTIONS & ANSWERSFrequently asked questions
Is a PVC cutter suitable for PEX?
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.
Was this tool independently tested?
No. This review uses manufacturer documentation and task-fit analysis. It does not claim measured field performance, durability or comparative test results.
