Milwaukee 48-22-4252 Mini Copper Tubing Cutter
ReviewedPros
- Compact head reaches into tight spaces behind walls, under sinks, and between joists where a standard cutter cannot rotate
- Rugged metal construction with a chrome plated finish holds up to job site abuse better than budget plastic body cutters
- Replaceable cutting wheel extends tool life instead of forcing a full replacement when the blade dulls
Cons
- Small cutting capacity means it cannot handle larger copper pipe, so it is a companion tool rather than a one cutter solution
- The compact body gives less leverage than a full size cutter, so thicker wall copper takes more hand force and more turns
The Milwaukee 48-22-4252 is a mini copper tubing cutter designed for close quarters work on small diameter copper pipe. It uses a compact metal body and a replaceable cutting wheel, and it is sized to fit where a standard cutter simply will not go. It is a specialty plumbing tool, not a general purpose pipe cutter.
Real-World Notes
Owner feedback themes point to the same pattern: buyers like how small the head is and how easily it slips into tight spots behind walls and under fixtures, and they report clean cuts on small copper lines with a little patience. The most common complaints are that it is too small for anything beyond small diameter tubing and that cutting harder or thicker wall copper takes noticeably more effort than a full size cutter. A recurring practical note is to keep a spare cutting wheel on hand, since the wheel is the part that wears out first.

Who Should Consider Something Else
Skip this if you mostly cut larger diameter copper, run a lot of rigid or thick wall pipe, or want one cutter to cover every job in the house. In those cases a full size constant swing cutter or a close quarters model with a wider capacity will serve you better, and this mini cutter is best treated as a second tool for tight spots.
FAQs
What size copper tubing does the Milwaukee 48-22-4252 cut?
It is a mini cutter intended for small diameter copper tubing, roughly 1/8 inch to 5/8 inch outer diameter. It is not designed for larger pipe.
Does it come with a replacement cutting wheel?
The tool ships with its cutting wheel installed. Replacement wheels are sold separately under the Milwaukee 48-22-4253 part number.
Is this the same as the Milwaukee constant swing cutter?
No. The 48-22-4252 is the mini close quarters model, while the constant swing cutters are larger tools with a different body and a wider cutting capacity.
Can it cut other materials besides copper?
It is designed for copper tubing. It is not intended for steel, PVC, or PEX, and using it on harder materials will dull or damage the wheel.
Is it worth buying if I already own a full size tubing cutter?
Yes, if you do plumbing work in tight spaces. The mini cutter reaches spots a full size cutter cannot, so the two tools complement each other rather than replace one another.
Our verdict
The Milwaukee 48-22-4252 is a well built mini copper tubing cutter that earns its place in a plumbing bag for tight space work on small copper lines. Its compact size is both its strength and its limit, so it works best alongside a full size cutter rather than as your only one. If your jobs regularly put you behind walls and under fixtures, it is an easy recommendation.
