Product Description
Milwaukee 1 in. Constant Swing Copper Tubing Cutter
Model Number: 48-22-4259
The Milwaukee 48-22-4259 is a 1 in. Constant Swing Copper Tubing Cutter — a compact professional-grade tubing cutter for cutting copper, aluminum, brass, and thin-wall steel tubing cleanly and squarely in plumbing, HVAC, refrigeration, and mechanical work where the 1 in. capacity handles the most common residential and light commercial tubing sizes efficiently. Milwaukee's Constant Swing design is the key engineering feature that distinguishes this cutter from standard rotary tubing cutters — it maintains a fixed, consistent handle swing arc throughout the entire cutting range from minimum to maximum tube diameter capacity. Standard tubing cutters change their handle swing geometry dramatically as the cutter is adjusted for different tube sizes — the handle path that produces effective cutting action at 3/4 in. tube is different from the efficient path at 1/2 in. tube, requiring the operator to constantly adapt their cutting motion as tube diameter changes. Constant Swing eliminates this adaptation requirement, allowing the operator to use the same efficient cutting motion for every tube size within the cutter's range for faster, less fatiguing tubing cutting throughout the workday.
The 1 in. maximum capacity covers the full range of standard residential plumbing tubing sizes — 3/8 in. OD, 1/2 in. OD, 5/8 in. OD, 3/4 in. OD, and 7/8 in. OD copper tubing used in residential water supply, in-wall plumbing, HVAC refrigeration lines, and similar applications are all within the cutter's working range. The precision cutting wheel produces clean, square cut ends with minimal wall deformation and small interior burrs that require only a quick reaming pass before making solder, press, or compression fittings. The reaming blade integrated into the cutter body removes the interior burr created by the cutting wheel on the tube inner diameter — interior burrs must be removed before any type of fitting connection to ensure proper fitting engagement and prevent burr debris from entering the water supply or refrigeration system downstream.
For larger tubing requiring up to 1-5/8 in. capacity, see the Milwaukee 48-22-4252 ratcheting cutter and the Milwaukee 48-22-4250 constant swing cutter — see Milwaukee's complete tubing cutter lineup for all available capacity and style options.
