Key Features
Overview
The Klein 1-3/8-in. Constant Swing Tubing Cutter (50046) is a tubing cutter for copper and aluminum tube from 1/8 inch up to 1-3/8 inch O.D. The compact body is made for working in tight spaces.
Free-spinning rollers and a long-lasting blade give smooth cuts, and the contoured adjustment knob sets the cut capacity. A retractable telescoping deburring tool is built in, so you can clean up the inside edge of the cut without reaching for a second tool.
A spare blade (Cat. No. 50054) is stored in the knob so a dull blade does not shut down a job. The compact design is built for tight spaces.
At 22.4 ounces with a zinc alloy body, it is a solid cutter for anyone who cuts copper tube regularly.
