Product Description
Milwaukee 1 in. Mini Copper Tubing Cutter
Model Number: 48-22-4251
The Milwaukee 48-22-4251 is a 1 in. Mini Copper Tubing Cutter — a compact, lightweight tubing cutter engineered specifically for working in the tight spaces that plumbing, HVAC, and refrigeration work regularly presents. The Mini designation refers to the reduced body size and compact profile of this cutter compared to standard-size tubing cutters — the mini format fits into cabinet sink bases, wall cavities, framing bays, under-vanity spaces, and mechanical room tight quarters where the larger body of standard tubing cutters prevents positioning the tool for a complete rotation around the tube. The compact design does not sacrifice cutting capacity — the 1 in. capacity covers the full range of standard residential copper tubing sizes including 1/4 in., 3/8 in., 1/2 in., 5/8 in., 3/4 in., and 7/8 in. OD copper tube used throughout residential water supply, in-wall plumbing, radiant heating, and HVAC refrigeration line work.
Milwaukee builds the Mini Copper Tubing Cutter with the same precision-ground cutting wheel and durable construction as standard-size Milwaukee tubing cutters — the mini format does not compromise the cut quality that the full-size design delivers. The cutting wheel produces clean, square cut ends with minimal wall deformation and a small interior burr that requires only a quick reaming pass before solder, press, or compression fitting installation. A reaming blade integrated into the cutter body removes this interior burr for immediately fitting-ready cut ends without reaching for a separate deburring tool. The compact body and lightweight construction reduce hand fatigue during sustained plumbing work in confined spaces where the awkward working position already adds fatigue from the installation conditions.
See Milwaukee's complete tubing cutter lineup for larger-capacity cutters for 2 in. and larger copper pipe and for the ratcheting and constant swing designs for different working clearance conditions.
