Drilling a Euro cylinder is a necessary skill for locksmiths and individuals who need to access a locked door without a key. Euro cylinders are a common type of lock found in homes, businesses, and other buildings. They are known for their high security, but they can be drilled if the proper techniques are used.

In this comprehensive guide, we will provide step-by-step instructions on how to drill a Euro cylinder, including the tools and materials needed, safety precautions, and troubleshooting tips.

Tools and Materials

Before you begin, gather the following tools and materials:

• Electric drill
• Drill bits (2mm, 3mm, 4mm, 5mm)
• Center punch
• Hammer
• Safety glasses
• Gloves
• Dust mask

Safety Precautions

Drilling a Euro cylinder can be dangerous if proper safety precautions are not taken. Always wear safety glasses, gloves, and a dust mask to protect yourself from flying debris and dust. Secure the door in place to prevent it from moving while you are drilling.

Step-by-Step Instructions

1. Mark the Center Point

Use a center punch to mark the center of the cylinder at the top and bottom. This will serve as the guide for your drill bit.

2. Drill the Pilot Hole (2mm)

Attach the 2mm drill bit to the electric drill and drill a pilot hole at the center point. Go slowly and apply light pressure to avoid damaging the cylinder.

3. Enlarge the Hole (3mm)

Change the drill bit to 3mm and enlarge the pilot hole by drilling around the circumference of the cylinder. Continue drilling until the hole is slightly larger than the diameter of the cylinder.

4. Remove the Retaining Pin (4mm)

Attach the 4mm drill bit and drill a hole through the retaining pin that holds the cylinder in place. The pin is located at the bottom of the cylinder.

5. Extract the Cylinder

Once the retaining pin is removed, the cylinder can be easily extracted from the door. Use a screwdriver or a pair of pliers to pull the cylinder out.

6. Remove the Plug (5mm)

The plug is the part of the cylinder that contains the keyway. Attach the 5mm drill bit and drill through the plug to remove it.

7. Open the Door

With the plug removed, you will have access to the door latch. Use a screwdriver or a key to open the door.

Troubleshooting Tips

• The drill bit is not cutting through the cylinder: Ensure that you are using the correct drill bit size and applying sufficient pressure.
• The cylinder is spinning while you are drilling: Hold the cylinder firmly in place with a pair of pliers or a vise.
• The retaining pin is not coming out: Make sure that you are drilling through the center of the pin.
• The plug is not coming out: Drill through the plug more deeply until it breaks free.
