Rivet removal, a seemingly mundane task, can transform into a daunting ordeal without the proper knowledge. However, with the right techniques and tools, you can master the art of rivet extraction. Whether you’re a seasoned professional or a novice handyman, understanding how to remove rivets is an invaluable skill that can save you time, money, and frustration.
The first step is to gather the necessary tools. You’ll need a rivet gun, a drill, and safety glasses. If you don’t have a rivet gun, you can rent one from a hardware store. Once you have your tools, you’re ready to begin the process. Place the drill bit over the rivet’s head and start drilling. As the drill bit penetrates the metal, it will create a hole in the rivet. Once the hole is deep enough, you can use the rivet gun to push the rivet out of the hole.
If you’re removing a rivet from a delicate surface, you can use a washer or a piece of scrap metal to protect the surface from damage. Place the washer or scrap metal over the rivet’s head before you start drilling. This will help to distribute the force of the drill and prevent the surface from being scratched or dented. Removing rivets may seem like a simple task, but with the right tools and techniques, you can ensure a clean and efficient removal process.
Gathering the Necessary Tools
To successfully remove a rivet, you’ll need an appropriate tool kit. Here’s a comprehensive list of essential tools:
| Tool | Purpose |
|---|---|
| Rivet Gun | Used to install and remove rivets |
| Drill and Drill Bits | To bore out the head of the rivet |
| Hammer and Punch | To drive the drill bit into the rivet head and break it free |
| Rivet Extractor | A specialized tool designed specifically for removing rivets |
| Clamps or Vise | To secure the workpiece during the removal process |
| Safety Glasses and Gloves | Essential personal protective equipment for safety |
Additionally, consider the following factors when selecting your tools:
– Rivet Material: Choose drill bits and rivet extractors that are compatible with the material of the rivet.
– Rivet Size: Ensure your drill bits and rivet extractors are the correct size for the rivets you need to remove.
– Durability: Invest in high-quality tools that can withstand the demands of rivet removal.
Choosing the Right Punch
Selecting the appropriate punch is crucial for effective rivet removal. Here are some key factors to consider:
Punch Size and Shape
The diameter of the punch tip should match the diameter of the rivet head. A punch that is too large can damage the rivet or surrounding material, while a punch that is too small will not be able to grip the rivet securely.
The shape of the punch tip also matters. A flat punch is suitable for most rivets, but a conical or domed punch may be necessary for rivets with specific head shapes.
Punch Material and Hardness
Punches should be made of high-quality, durable steel. The hardness of the punch should be greater than the hardness of the rivet to ensure proper penetration. Common materials for punches include tool steel, hardened steel, and carbide.
Hardness Table
| Material | Hardness (Rockwell C) |
|---|---|
| Mild Steel | 20-30 |
| Tool Steel | 50-65 |
| Hardened Steel | 60-70 |
| Carbide | 80-90 |
**Preparing the Work Surface**
Before beginning any rivet removal process, it is essential to establish a safe and suitable work surface. This involves taking the following steps to create a stable and secure environment:
**1. Choose a flat and stable surface:**
Select a work surface that is flat, even, and sturdy enough to support the object containing the rivet. Ensure that the surface can withstand the force applied during the rivet removal process.
**2. Protect the work surface:**
Place a protective covering, such as a cloth or cardboard, over the work surface to prevent it from getting scratched or damaged. This will prevent any scratches that would make the work surface become unsafe or unusable.
**3. Secure the object:**
Securely fasten the object containing the rivet to the work surface using clamps, a vise, or other appropriate methods. Ensure that the object is firmly held in place to prevent it from moving or shifting during the rivet removal process. Placing the object in a vise or clamp ensures that the object is held in place during the drilling process, which prevents any injury from occurring to the hands or other parts of the body. Additionally, the vise or clamp will hold the object in place which will make it easier to remove the rivet.

| Drill Bit Size | Rivet Shaft Diameter |
|---|---|
| 1/16″ | 1/16″ |
| 3/32″ | 3/32″ |
| 1/8″ | 1/8″ |
Drilling the Pilot Hole
The size of the pilot hole will depend on the size of the rivet head. To determine the correct drill bit size, measure the diameter of the rivet head. The pilot hole should be slightly larger than the head, but not so large that you risk drilling through the other side of the metal. A drill bit that is 1/16 inch larger than the rivet head is a good starting point.
Once you have the correct drill bit, clamp the metal workpiece in place to prevent it from moving. Position the drill bit over the center of the rivet head and begin drilling. Apply light pressure and drill slowly to avoid drilling too deep.
Drilling Depth
The depth of the pilot hole should be slightly shallower than the length of the rivet shaft. This will allow the rivet to expand properly when it is set.
To determine the correct drilling depth, measure the length of the rivet shaft. Then, subtract 1/8 inch from the measurement. This will give you the maximum drilling depth.
Once you have drilled the pilot hole, remove the drill bit and check the depth. You may need to adjust the depth of the hole slightly to ensure that the rivet will fit properly.
Drilling the pilot hole is a critical step in the riveting process. By following these steps, you can ensure that the rivet is installed correctly and securely.
| Rivet Diameter | Drill Bit Size |
|---|---|
| 1/8 inch | 1/4 inch |
| 3/16 inch | 5/16 inch |
| 1/4 inch | 5/16 inch |
| 5/16 inch | 3/8 inch |
Inserting the Rivet
Once the holes have been drilled, you need to insert the rivet. Rivets typically consist of a head, a pin, and a tail. The head is the part that will be visible on the surface of the material, while the pin is the part that will be inserted into the hole. The tail is the part that will be formed by the excess material from the pin after it has been hammered or pressed into place.
To insert the rivet, follow these steps:
-
Select the correct rivet size. The rivet should be slightly larger in diameter than the hole.
-
Insert the rivet into the hole. The tail of the rivet should be facing the outside of the material.
-
Hold the rivet in place. You can use a rivet gun or a pair of pliers to hold the rivet in place.
-
Hammer or press the rivet into place. The rivet should be hammered or pressed until the tail is completely formed.
-
Inspect the rivet. Make sure that the rivet is securely in place and that the head is flush with the surface of the material.
-
Additional tips for inserting rivets:
- Use a rivet gun or a pair of pliers to hold the rivet in place. This will help to prevent the rivet from slipping out of the hole.
- Use a hammer or a press to set the rivet. Do not use a screwdriver or other sharp object to set the rivet, as this could damage the rivet or the material.
- Make sure that the rivet is set flush with the surface of the material. If the rivet is set too high, it could interfere with the operation of the equipment or cause injury.
- If the rivet is set too low, it could weaken the joint.
Setting the Rivet Head
The following steps provide a detailed guide to setting the rivet head:
1. Choose the Appropriate Dolly
Select a dolly that matches the diameter and shape of the rivet head. This ensures a proper fit and secure grip.
2. Position the Dolly
Place the dolly over the rivet head, ensuring it is centered and aligned perpendicular to the surface.
3. Apply Pressure
Gradually apply pressure to the dolly using a hammer or press. The amount of pressure will depend on the size and material of the rivet.
4. Check for Flushness
Continue hammering until the rivet head becomes flush with the surface. Avoid over-hammering, as this can damage the rivet or surrounding material.
5. Examine the Head
Inspect the rivet head to ensure it is properly formed and symmetrical. Any irregularities may indicate a problem with the setting process.
6. Remove the Dolly
Once the rivet head is set, carefully remove the dolly. Hold the dolly perpendicular to the surface to avoid damaging the rivet.
7. Inspect the Rivet
Examine the rivet carefully for any signs of damage or deformation. If any issues are detected, the rivet may need to be replaced.
Peening the Rivet
To peen a rivet, you will need a ball-peen hammer and a rivet set. A ball-peen hammer has a round, peening head on one end and a flat face on the other. A rivet set is a tool that has a concave surface that matches the shape of the rivet head.
To peen a rivet, first place the rivet set over the head of the rivet. Then, hold the hammer in your hand and strike the rivet set with the ball-peen end of the hammer. This will cause the metal of the rivet head to flow into the concave surface of the rivet set, forming a smooth, rounded head.
Important Tips for Peening a Rivet
Here are a few important tips for peening a rivet:
- Use a ball-peen hammer that is the correct size for the rivet. A hammer that is too large or too small will not peen the rivet properly.
- Hold the hammer at a slight angle to the rivet set. This will help to create a smooth, rounded head.
- Strike the rivet set with a firm, even blow. Do not strike too hard, as this can damage the rivet.
- Peen the rivet until the head is smooth and rounded. The head should not be too high or too low.
- If the rivet head is too high, you can use a file to file it down. If the rivet head is too low, you can use a hammer and dolly to raise it.
- Wear safety glasses when peening a rivet. The hammer can fly off the rivet set and hit you in the eye.
- Practice peening rivets on scrap metal before you attempt to peen rivets on a real project. This will help you to get the hang of it.
- Different types of rivets require different peening techniques.
| Rivet Type | Peening Technique |
|---|---|
| Blind rivets | The rivet is peened from the inside of the hole. |
| Solid rivets | The rivet is peened from the outside of the hole. |
| Pop rivets | The rivet is peened with a special tool called a pop rivet gun. |
Finishing and Inspecting the Job
9. Finishing the Job
After removing the rivet, you need to finish the job by cleaning up the area. Use a wire brush to clean any remaining debris or burrs from the hole. If there are any sharp edges, file them down until they are smooth.
Next, you need to inspect the hole to make sure it is not damaged. If the hole is too large or damaged, you will need to use a rivet nut or other type of fastener to repair it.
Once you have inspected the hole and cleaned it up, you can apply a sealant or paint to protect it from corrosion. This will help to extend the life of the repair.
Finally, you need to check the rivet that you removed to make sure it is not damaged. If it is damaged, you will need to replace it with a new one.

How To Take Out A Rivet
Rivets are permanent fasteners that are used to join two pieces of metal together. They are typically made of steel, aluminum, or copper. Rivets are installed by inserting them into a hole that has been drilled through the two pieces of metal. The rivet is then hammered or pressed into place, causing the metal to expand and fill the hole. This creates a strong and permanent bond between the two pieces of metal.
To remove a rivet, you will need to drill out the head of the rivet. This can be done with a drill bit that is slightly smaller than the diameter of the rivet head. Once the head of the rivet has been drilled off, you can use a punch to drive the rivet out of the hole.
Here are the steps on how to take out a rivet:
- Drill out the head of the rivet. Use a drill bit that is slightly smaller than the diameter of the rivet head. Drill slowly and carefully, so as not to damage the surrounding metal.
- Once the head of the rivet has been drilled off, you can use a punch to drive the rivet out of the hole. Place the punch on the end of the rivet and tap it with a hammer. The rivet should come out of the hole easily.
- If the rivet is stuck, you can try using a penetrating oil to loosen it. Apply the penetrating oil to the rivet and let it sit for a few minutes. Then, try to drive the rivet out of the hole again.
