RIDGID 32050 Model 150 Tubing Cutter Review

Copper pipe doesn’t forgive a bad cut — an out-of-square end means a leaky joint no matter how good your soldering technique is. The RIDGID 32050 (Model 150) has been the standard tubing cutter in plumbing trucks for generations, and after using it through a full bathroom repipe and several smaller repair jobs, it’s easy to see why the design hasn’t needed to change much.

What We Tested

Cutting 1/2″ and 3/4″ copper pipe for a bathroom repipe, tight-quarters cuts in a wall cavity with limited swing room, and repeated cuts to check blade wear and consistency of the cut angle over roughly 40 total cuts.

Performance

The cut quality is the whole point of this tool, and it delivers a clean, square end on copper every time as long as you take it slow and let the wheel do the work instead of forcing the feed screw. Square cuts matter more than most DIYers realize — an angled cut means less surface contact in a sweated joint and a higher chance of a pinhole leak down the road.

The rapid-acting feed screw speeds up setup between cuts noticeably compared to older standard-thread designs — you can slide it open or closed instead of cranking through every thread. In tight wall-cavity cuts where there wasn’t room for a full swing, the compact frame still managed a full cut by walking it around the pipe in smaller increments.

Built-in storage for a spare cutter wheel in the handle is a small but genuinely useful detail — wheels do eventually dull or chip, and having a replacement on hand mid-job beats a trip to the hardware store.

How It Compares

Vs. a basic mini tubing cutter: Mini cutters are more compact for very tight spaces but the smaller cutting wheel needs more revolutions per cut and dulls faster under regular use.

Vs. a plastic-body budget cutter: Budget cutters work fine for occasional use but the frame flexes under pressure on harder alloys, which leads to less consistent, less square cuts over time.

Who It’s For

Anyone doing copper plumbing repair or repipe work — this is the standard tool for a reason, and the lifetime warranty and all-metal construction mean it’ll outlast most homeowners’ plumbing needs several times over. If you’re only ever cutting one or two pipes for a single repair, a basic cutter or even a hacksaw with a miter guide will get by, but this is the tool a plumber actually carries.

Pros

• Consistently square, clean cuts critical for leak-free sweated joints
• Rapid-acting feed screw speeds up work between cuts
• All-metal cast construction holds up to years of use
• Built-in spare wheel storage in the handle
• Full lifetime warranty, made in USA

Cons

• Larger frame is harder to maneuver in extremely tight cavities than a mini cutter
• Replacement cutter wheels are an added cost over time
• No ratcheting mechanism for one-handed operation on larger pipe
