Knipex 90 31 03 BKA KNIPEX TubiX XL Pipe Cutter is built for clean, controlled cutting on metal pipe and conduit in the shop or out on a service call. This is a hand pipe cutter designed for cutting metal pipe and conduit cleanly in the field. Model Number: 90 31 03 BKA. If you work with copper, brass, stainless steel gas and water pipe, or electrical rigid steel conduit, this tool is made to give you a cleaner cut than a saw and with less mess to clean up after.

The big selling point here is range. This cutter works on pipe diameters from 1/4 inch to 3 inches, which lets one tool cover a lot of day-to-day plumbing, HVAC, and electrical conduit work. It also cuts wall thicknesses up to 5/64 inch, or 2 mm. In practical terms, that means it is meant for common metal tubing and pipe work where you want a square, predictable cut without dragging out a larger bench setup.

Knipex gives this pipe cutter a spring-loaded QuickLock mechanism so you can position it quickly and precisely on the pipe in one step. Once locked, it stays put, which matters when you are working overhead, in a mechanical room, or anywhere you do not have the luxury of a bench vise and both hands free. The high-quality needle bearings, combined with the cutting wheel and four guide rollers, are there for one reason: smoother tracking around the pipe and less fighting the tool while you turn it.

The construction is geared toward jobsite durability without making the tool overly heavy. The housing is lightweight aluminum, while the cutting wheel is made from high-grade ball-bearing steel. That is a smart mix for a hand cutter like this. The body keeps overall weight manageable at 2.09 lbs, while the wheel material is chosen for wear resistance where it counts. Knipex also includes a removable precision-ground deburring tool that slides out of the way when not in use, so you can clean up the cut with the same tool instead of digging through the bag for something else.

Another practical detail is serviceability. The cutting wheel can be replaced without tools, and Knipex stores a spare wheel right in the handle. That kind of feature sounds small until you are on a job, the wheel is done, and you do not want the whole task grinding to a halt over a simple wear part. This cutter is hand powered, compact enough to carry, and built for tradespeople who want a durable metal pipe cutter that covers a wide size range without becoming bulky or awkward.

Who is it for? This is a strong fit for plumbers, HVAC installers, electricians working with rigid steel conduit, maintenance techs, and serious DIY users doing metal pipe work at a high level. If your priority is quick setup, consistent cuts, and an all-in-one hand pipe cutter with built-in deburring and on-board spare wheel storage, this Knipex pipe cutter makes a lot of sense. If you rarely cut metal pipe or only work in a very narrow size range, it may be more tool than you need, but for regular field use it is built the right way.
