Milwaukee 48-22-4259 Copper Tubing Cutter 1/8 to 1-1/8 Inch

Product Description

The MILWAUKEE ELECTRIC TOOL CORP 48-22-4259 is a constant-swing copper tubing cutter built for field use by plumbers and HVAC technicians who need clean, accurate cuts on copper pipe. The tool handles pipe from 1/8 inch up to 1-1/8 inch capacity. A four-roller design keeps the cutter tracking true, preventing walking and producing straighter cuts than standard single-roller designs. Chrome-plated rollers resist rust, extending the service life of the tool in wet or high-humidity environments. An on-board reamer is integrated into the tool body for fast deburring without switching to a separate tool.

This tubing cutter is suited for residential and commercial plumbing, refrigeration line sets, and HVAC copper line installation. The constant-swing design eliminates the need to back the cutting wheel off between rotations, making it practical in tight spaces where full rotation clearance is limited. Plumbers, pipefitters, and HVAC technicians working with Type K, L, or M copper pipe will find this tool applicable across standard service and new-installation work.

Key Features

• Constant-swing design produces straighter, cleaner cuts on copper tubing
• Four-roller system prevents cutter walking during rotation
• Chrome rollers provide corrosion resistance for extended service life
• On-board reamer enables deburring without a separate tool
• Pipe capacity range of 1/8 inch to 1-1/8 inch covers common residential and light commercial copper sizes

Compatibility

Designed for use with copper tubing in the 1/8 inch to 1-1/8 inch outside-diameter range, consistent with common plumbing and HVAC refrigerant line applications.

Installation Notes

This tool is used by licensed plumbers and HVAC technicians during pipe preparation before soldering, flaring, or press-fitting connections. Ensure the pipe is fully supported and the cutter wheel is aligned square to the tubing before applying cutting pressure. After cutting, use the integrated reamer to remove the inner burr before making any connection, as burrs restrict flow and can damage valve seats. Follow applicable plumbing codes such as the IPC or IFGC when installing copper piping systems.
