How to Cut Copper Tubing?

Published in Copper Cutting 3 mins read

Cutting copper tubing is straightforward using a pipe cutter and requires a few key steps. The process involves scoring the pipe, rotating the cutter, and then finishing the cut.

Step-by-Step Guide to Cutting Copper Tubing

Here's a detailed guide on how to cut copper tubing, utilizing the information from the provided reference:

  1. Prepare the Tubing and Cutter:

    • Make sure the copper tubing is clean and free of any debris.
    • Mark the exact spot where you want to make the cut using a marker or pencil. This will serve as your guide when using the cutter.
    • Open the jaws of your copper pipe cutter by turning the adjustment knob counterclockwise.

  2. Align and Score:

    • Position the copper pipe cutter so the cutting wheel is aligned perfectly with your marked line on the tubing.
    • Tighten the adjustment knob on the cutter until the blade makes contact and scores the pipe. Be careful not to over-tighten initially; the goal is just to start the cut.

  3. Rotate the Cutter:

    • After the initial scoring, rotate the cutter completely around the copper pipe.
    • After each full rotation, tighten the knob slightly to increase the pressure of the blade.
    • Continue rotating and gradually tightening until the pipe separates. Avoid forcing the cut or overtightening the cutter as this can crush or damage the pipe.

  4. Remove the Cutter:

    • Once the tubing is cut, fully loosen the adjustment knob on the cutter by turning it counterclockwise.
    • Remove the copper pipe cutter from the tubing.

  5. Clean the Cut:

    • Use a Reamer: After cutting, the edge of the copper tube will have a burr or rough edge and will require reaming.
    • Insert a reamer into the cut end of the tube and remove any burrs. This will ensure a smooth and clean edge.

Key Points to Remember:

  • Start Gently: Begin with light scoring and increase pressure gradually.
  • Avoid Over-Tightening: Over-tightening can damage the cutter or distort the tubing.
  • Reaming is Essential: Reaming ensures a smooth cut, preventing issues when connecting pipes.
