Step 2 · Cut the Copper Pipe
Measure and mark the copper pipe to the desired length using a tape measure and a permanent marker. Place the tubing cutter on the mark, ensuring the cutting wheel is aligned perfectly. Tighten the knob until the wheel gently makes contact with the copper. Rotate the cutter one full revolution around the pipe. After the first rotation, tighten the knob a quarter-turn and rotate again. Continue this process of rotate-and-tighten until the pipe snaps off cleanly. This method ensures a perfectly square and clean cut, which is essential for the pipe to seat properly in the fitting.
