The Titan 85510 is a self-adjusting brake line cutter that automatically adjusts cutting pressure and cuts 3/16" (4.75mm) brake line tubing. It is faster and more precise than conventional cutters, and the ratcheting mechanism in the head minimizes space requirements - meaning it can be used in tight spaces directly on the vehicle. This tool also allows for a 1/4" spanner wrench to be inserted into the end of the handle for increased leverage.
