The big-rig cutter that makes short work of 2-5/8-inch commercial lines.

When your job calls for cutting copper pipe up to 2-⅝ inches (66 mm) in diameter, you want a tool that does not require superhuman grip strength. The Ridgid 31642 is the only quick-action cutter in this lineup — you squeeze the spring-loaded handle, the blade clamps down instantly, and you spin. Owners mention it is the best copper pipe cutter they have ever used, and that it cuts “like a charm” even on larger pipe where the constant-swing models would need endless knob-turning. At 1.8 pounds, however, it is noticeably heavier than the Lenox TC138 (1 pound) — so it is overkill for small repair kits but a lifesaver on all-day commercial runs.

The I-beam frame and hardened wear surfaces are built for abuse. You get a fold-away reamer for cleaning up the inside edge, and the X-CEL wheel pin lets you swap the blade without tools. The spring that makes it fast can occasionally pop off, but customers note that is a 30-minute fix. This is a nearly three-inch capacity that no other cutter here matches, making it the only choice if you ever touch 2-inch copper.

The compact workhorse built for cutting in the cramped corners of a service panel.

A lot of pipe cutting happens in spaces where you can barely fit one hand, let alone a full swing. Klein designed the 50046 for exactly that — a 1-⅜-inch (34 mm) max capacity that fits between studs and inside equipment bays. One buyer who cuts “a lot of half and 3/4″ emt” says it works great and leaves a very smooth cut. The free-spinning rollers let you track the cut without fighting resistance, and the zinc alloy frame keeps the blade from wobbling. Unlike the bigger Ridgid 31642, this is a constant-swing model, so you tighten the knob a little each rotation for fine control.

The telescoping deburring tool folds out for post-cut cleanup, which saves you reaching for a separate reamer. A replacement blade stores in the handle, and the whole cutter weighs 1.35 pounds — right in the middle of the pack. Reviewers point out it is “incredibly sturdy” and “makes all the other pipe cutters look like toys.” Your only real limit is the 1-⅜-inch capacity, which falls short of the 2-⅝-inch max on the Ridgid 31642 if you ever work with larger waste lines.

The Ridgid classic that ended one buyer’s struggle with ragged threads for good.

One buyer sums up the pain perfectly: “My cheap pipe cutters kept making threads on my pipe instead of cutting.” Once you switch to the 31622, that frustration disappears. This cutter handles ⅛-inch to 1-⅛-inch (28.6 mm) copper, stainless steel, and aluminum with an enclosed feed screw that stays clean — no clogging or jamming from debris. The grooved rollers let you cut right up next to a flare without crushing it, and the fold-away reamer cleans the burr in one motion. Unlike the heavier 1.8-pound Ridgid 31642, this one weighs only 12 ounces, making it far easier to control on smaller pipe.

The X-CEL knob gives a firm grip, and the ball-detent wheel pin lets you swap the cutter wheel without hunting for a lost clip. A spare wheel lives inside the knob. The catch is that the model you receive may be a grey version instead of the white one shown in the product image — shoppers say the pictured model and delivery do not always match, even though the model number is correct. It is still a Ridgid, so the cutting quality holds up. The 1-⅛-inch capacity means it cannot handle the 2-⅝-inch pipe of the 31642, but for standard residential plumbing it is perfect.

The weighty, solid cutter that never wanders off the cutting line.

If you have ever had a cutter “walk” — drift sideways and spiral around the pipe instead of tracking straight — you know how frustrating a ruined cut is. The Lenox TC138 uses a full-stop feed system that keeps the wheel and rollers from touching when not in use, so the blade stays sharp and the tracking stays true. Buyers report that it “cuts 1/4″ copper/sterling silver tubing well” and never walks or breaks track. At 1 pound, it is noticeably heavier than the 12-ounce RIGID 31622, but that heft gives you a planted feel that cheaper cutters lack. The trade-off is that it is actually heavier than some buyers prefer — one reviewer calls it “a little heavy” even though they like the quality.

Lenox throws in an extra cutting wheel, and the stainless-steel blade lasts through many jobs. The constant-swing adjuster spins fast, so you are not turning a knob forever, but there is no quick-release mechanism — you unscrew it all the way to remove the cutter from the pipe. That is a minor slowdown compared to the Klein 50046’s clean retraction, but the Lenox wins on tracking stability. For thin-wall copper, EMT, and even sterling silver, this is the pro-grade feel without the quick-action bulk.

A surprisingly capable budget cutter that chewed through thick stainless without complaint.

Not everyone needs a daily pro-grade tool. For the homeowner or weekend plumber who cuts copper once a quarter, the iCrimp CT-532 delivers clean results without a big investment. It cuts copper, brass, aluminum, thin-walled steel, and CSST (corrugated stainless steel tubing — flexible gas pipe) from 3/16-inch to 1-¼-inch (5-32 mm). One buyer reports it “cut through thick stainless tube easily” — a task that would ruin a cheap blade. The 6-roller tracking system keeps the cut straight and prevents spiraling, which is the same design principle you get from cutters costing three times as much.

You get two spare replacement blades in the package, and the aluminum alloy frame keeps the weight down. The catch is that the cutting wheel can chip if you push too hard on heavy material — one buyer says it worked on a bicycle steerer tube but chipped the wheel after one job. That makes this cutter adequate for light use, not commercial daily grinding. It also lacks the built-in deburring tool you get on the Klein 50046 or the Ridgid 31622, so you will need a separate reamer for the inside edge.
