Klein Tools 50047 Mini Tubing Cutter – 1/8 inch to 1-1/8 inch O.D. for Copper & Aluminum (Spare Blade)

Overview

The Klein Tools 50047 Mini Tubing Cutter is built to handle copper and aluminum tubing with precision in a compact format. It supports tubing from 1/8 inch up to 1-1/8 inch outer diameter, and up to 1 inch inner diameter, making it versatile for small-diameter runs in HVAC, plumbing, or electrical installations. The tool’s slim profile shines in tight spaces such as behind panels, in conduit runs, or inside cabinets where a larger cutter would struggle. A durable blade delivers consistent bites, while free-spinning rollers help produce smooth, square cuts. A spare blade is stored in the handle for quick swaps between jobs.
