Milwaukee 48-22-4258 Mini Tube Cutter 1/8 to 7/8 Inch

Product Description

The Milwaukee Electric Tool Corp 48-22-4258 is a compact mini tube cutter designed for cutting copper tubing in tight spaces where a standard cutter cannot reach. With a cutting capacity range of 1/8 inch to 7/8 inch, it handles the small-diameter copper lines common in HVAC, refrigeration, and plumbing rough-in work. The tool features a proprietary adjustment mechanism engineered for extended service life, chrome-plated rollers for corrosion resistance, and an easy-grip knob that speeds up jaw adjustment during repetitive cuts. It is built for use by HVAC technicians, plumbers, and refrigeration mechanics who need a reliable compact cutter on the job.

This mini tube cutter is suited for residential and light commercial applications where access is limited, such as cutting copper supply lines in wall cavities, under sinks, or within equipment cabinets. It is a standard hand tool for any technician running or modifying copper tubing on refrigerant circuits, potable water lines, or hydronic systems. The 1/8 inch to 7/8 inch capacity covers the most common small-diameter copper sizes used in these trades.

Key Features

• Cutting capacity from 1/8 inch to 7/8 inch for small-diameter copper tubing
• Proprietary adjustment mechanism engineered for extended tool life
• Chrome-plated rollers resist rust and corrosion for durable field use

Compatibility

Designed for cutting copper tubing in standard small-diameter sizes from 1/8 inch to 7/8 inch, suitable for HVAC, refrigeration, and plumbing applications.

Installation Notes

This tool is used by licensed plumbers, HVAC technicians, and refrigeration mechanics for field cutting of copper tubing. Before cutting any tubing on an active system, isolate and depressurize the line per applicable code requirements, including IFGC or IPC guidelines for gas and water systems. Score the tubing with light, even pressure and advance the cutter gradually to produce a clean, square cut without deforming the tube end. Deburr the cut end before making any flare, swage, or solder connection.
