Key Features
Large Copper CapacityCuts Type K, L, and M copper from 1-1/4 in. to 2 in. pipe sizes. That gives plumbers a faster way to handle bigger copper tubing without reaching for a manual cutter. Tight-Space AccessThe rotating head works with as little as 1.7 in. of clearance. That matters when the tubing is already installed near walls, joists, or other lines. Cleaner, Faster CutsThe Milwaukee 2479-20 copper tubing cutter uses a brushless motor, built-in LED light, and view window to speed up cuts while helping you stay on the cut line in dim mechanical spaces.
Overview
The Milwaukee 2479-20 M12 Brushless 1-1/4″ – 2″ Copper Tubing Cutter is a cordless copper tubing cutter built for plumbers and mechanical contractors who need fast, repeatable cuts on larger copper lines. This is a tube and pipe cutter designed for cutting installed Type K, L, and M copper tubing in tight spaces. Model Number: 2479-20.
What makes this tool matter on the job is the combination of speed, access, and cleaner results. Milwaukee built it to cut 1-1/4 in. to 2 in. copper tubing, with outside diameter coverage from 1-3/8 in. to 2-1/8 in. That gives you one cordless pipe cutter for a common range of larger plumbing and mechanical work, instead of fighting with a manual cutter when clearance is limited or production pace is high.
The rotating head is a big deal here. It helps the tool cut faster, reduces muscle fatigue, and lets you work with as little as 1.7 in. of clearance. If you are cutting copper near walls, other pipes, or in an equipment room where space is tight, that kind of access saves time and frustration. The automatic diameter adjustment also helps the cutter adapt to Type K, L, and M copper without the extra setup that slows down repetitive work.
Milwaukee also added a built-in LED light and a view window to illuminate the line of cut. That is not just a nice extra. In basements, utility rooms, and service areas where lighting is poor, it helps you line up the cut more clearly and keep moving without dragging over extra light. The automatic home button is there for the same reason: faster cycle-to-cycle work when you are making a lot of cuts in a day.
On the power side, this is a 12V cordless tool in the Milwaukee M12 platform, and it uses a brushless motor for longer life and solid runtime. Milwaukee states up to 100+ cuts per charge on an M12 REDLITHIUM XC4.0 battery. For anyone already on M12, that means easy battery sharing with service and install tools you likely already own. This bare tool does not include a battery or charger, so it makes the most sense for users already invested in the platform.
Physically, the tool is compact for its capacity at 12.6 in. long, 3.9 in. wide, 5.7 in. high, and 5.8 lbs. The housing uses plastic with a rubber overmold for grip and jobsite durability. The replaceable blade helps with long-term serviceability, which matters on a production tool that is expected to stay in rotation rather than get tossed when the cutting edge wears out.
Who should buy it? This Milwaukee tubing cutter is best for plumbers, HVAC mechanics, pipe installers, service techs, and remodel contractors working with larger copper tubing. If you mostly cut small tubing at a bench, this is more tool than you need. If you regularly cut installed 1-1/4 in. to 2 in. copper and want less hand fatigue, better access, and faster throughput, this tool earns its keep quickly.
Work in Tight Mechanical Spaces
This is where the tool separates itself from a standard manual cutter. The rotating head is built to get around installed copper where your hands and a conventional cutter struggle.
- Operates with as little as 1.7 in. of clearance
- Rotating head helps reduce muscle fatigue during repetitive cutting
Built for Repetitive Copper Cutting
For crews cutting larger copper all day, speed matters just as much as access. This cordless pipe cutter is designed to move through repeated cuts with less effort and less setup.
- Automatically adjusts to Type K, L, and M copper pipe diameters
- Automatic home button helps shorten time between cuts
Milwaukee 2479-20 M12 Brushless 1-1/4″ – 2″ Copper Tubing Cutter Visibility and Control

Pro Tip
If you are cutting installed copper close to a wall, line up the cut mark first using the view window, then let the rotating head do the work instead of trying to force the tool body into position. That makes the most of the 1.7 in. clearance design and keeps the cut cycle smoother.

Tool Nut’s Take
Tool Nut’s Take
A serious time-saver for bigger copper work
The Milwaukee 2479-20 M12 Brushless 1-1/4″ – 2″ Copper Tubing Cutter is the kind of specialty plumbing tool that pays off fast if you cut larger copper regularly.
- Who it’s for: Plumbers, HVAC installers, and service techs working on 1-1/4 in. to 2 in. copper in finished spaces, utility rooms, and mechanical areas.
- Why it stands out: The mix of auto-adjust cutting, rotating head access, LED visibility, and M12 cordless convenience makes it much easier to deal with installed copper than a manual cutter.
- Worth knowing: This is a bare tool, so plan on supplying your own M12 battery and charger. If you already run M12, that is a non-issue.
