How to Drill a Hole in Copper Tube

Tools and Materials Needed:

1. Drill with appropriate drill bits (metal or cobalt)

2. Safety goggles

3. Center punch

4. Hammer

5. Pipe cutter or hacksaw (if the copper tube needs to be cut)

6. Deburring tool or file

7. Lubricant (cutting fluid or oil)

Step 1: Prepare the Copper Tube

- If the copper tube needs to be cut to the desired length, use a pipe cutter or hacksaw.

- Secure the copper tube in a vise or clamp to prevent it from moving while drilling.

Step 2: Mark the Drilling Location

- Use a center punch to mark the exact spot where the hole needs to be drilled. Use a hammer to lightly tap the center punch to create a small indentation in the copper tube.

Step 3: Lubricate the Drill Bit

- Apply a lubricant or cutting fluid to the drill bit to help reduce friction and prevent damage to the bit and the copper tube.

Step 4: Choose the Right Drill Bit

- Select a drill bit made for metal working, such as a metal drill bit or a cobalt drill bit.

- Choose the appropriate drill bit size based on the desired hole diameter.

Step 5: Start Drilling

- Start drilling the hole slowly at a low speed to prevent the drill bit from slipping or damaging the copper tube.

- Gradually increase the drilling speed as needed.

- Apply light pressure while drilling to avoid bending or deforming the copper tube.

Step 6: Cool the Drill Bit

- Periodically stop drilling and allow the drill bit to cool down to prevent overheating and damage to the bit and the copper tube.

Step 7: Deburr the Hole

- Once the hole is drilled, use a deburring tool or file to remove any sharp edges or burrs around the hole.

- This helps ensure a smooth and clean finish.

Step 8: Clean the Tube

- Remove any metal shavings or debris from the hole and the copper tube surface.

Safety Precautions:

- Always wear safety goggles when working with power tools.

- Ensure that the drill is in good working condition and all connections are secure.

- Use caution when handling sharp drill bits and tools.

Remember, drilling holes in copper tubes can be a delicate task, so take your time and work carefully to avoid damage. If you're unsure about drilling holes in copper tubes, consider seeking the assistance of a professional plumber or handyman.
