The Knipex 90 25 40 PVC Pipe Cutter is a ratcheting pipe cutter built for thick-walled plastic and composite pipe. This is a pipe cutter designed for straight, controlled cutting on plumbing and installation work. Model Number: 90 25 40. If you are cutting multilayer or plastic pipe in the 26 to 40 mm range, this tool is built to do that job cleaner and with less effort than a saw.

Knipex rates this cutter for pipe diameters from 1 inch to 1 9/16 inches. The ratchet principle matters here because larger and thicker pipe can take real hand force with a one-shot cutter. Instead of trying to muscle through the cut, this tool advances in several strokes so you keep control, reduce strain, and stay on line.

One of the more useful details is the self-adapting pipe support. It positions pipes of different diameters correctly so the cut starts square and stays square. That is a big deal when you need a clean end for a proper fit, especially on composite pipe where a crooked cut can slow the whole install down.

The blade is made from special tool steel and is interchangeable, which gives this cutter a longer service life than disposable or throwaway-style cutters. The main tool body uses high-grade chrome vanadium electric steel with an oil-hardened build. In plain terms, this is not a light-duty cutter meant for occasional trim work. It is built like a real shop and jobsite hand tool.

Day-to-day use is helped by the multi-component handles and the ratcheting mechanism. Knipex also notes that the handles open by themselves thanks to the opening spring, which cuts down on extra hand movement when you are making repeated cuts. That adds up fast if you are roughing in multiple runs.

For maintenance, the replacement blade part number is 12 29 40. That is worth knowing because it means you can keep the cutter in service instead of replacing the whole tool once the blade wears. For contractors and serious DIY users, that is the kind of practical detail that makes a hand tool worth buying once.

This Knipex pipe cutter makes the most sense for plumbers, HVAC installers, remodelers, and anyone regularly working with thick-wall plastic or composite pipe. If your work calls for repeatable square cuts in that 26 to 40 mm range, the Knipex 90 25 40 PVC Pipe Cutter is the right kind of dedicated tool.
