What You'll Learn
Using a chisel and drill
Removing rivets may seem like a challenging task, but with the right tools, it can be done efficiently. Here is a detailed guide on using a chisel and drill to remove plastic rivets:
Preparing the Rivet
Before using the chisel and drill, you will need to prepare the rivet for removal. Place the chisel or screwdriver at the edge of the rivet head and strike it firmly with a hammer. Work around the rivet head, striking at different points, until the head begins to separate from the shaft. This will loosen the rivet and make it easier to remove.
Using the Chisel
Now, take your chisel and place its sharp end into the edge where the head of the rivet meets the surface. Wiggle the chisel a little to wedge it securely into place. Then, use your hammer to strike the dull or wide end of the chisel, knocking off the head of the rivet. Be cautious and controlled in your strikes to avoid injury.
Drilling Out the Rivet
Select a drill bit that is smaller than the pin of the rivet. Place the drill bit into the hole where the rivet head used to be and apply firm pressure while drilling at a steady pace. This will bore through the rivet and push it out. Remember to maintain a steady pace and pressure to prevent the bit from slipping and scratching the surface.
Final Steps
Once the rivet is pushed out, use a punch to drive out any remaining rivet material. Collect all rivet fragments to prevent potential damage or injury. Additionally, if you plan to reuse the plastic, be cautious of the heat generated during drilling, as it can melt the plastic. Consider using a Dremel to grind off the back of the rivet slowly, reducing the risk of damage.

Using a trim tool
To use a trim tool, first slip a piece of card stock under the tool to prevent scratches if you are prying against a painted surface. Then, insert the trim tool under the rivet's head and gently rock the tool to pop the rivet out. The larger surface area and bends in trim tools make it easier to apply the necessary force without damaging the rivet or the surrounding area.
Trim tools are available in various sets and packs, including a 5-piece upholstery and trim tool set, and a 2-piece clear plastic rivet trim removal tool set. You can also find trim tools at auto parts stores, such as O'Reilly's, and on Amazon.
In addition to using a trim tool, there are other methods for removing plastic rivets. These include using a drill bit to drive through the surface, grinding off the head of the rivet, or using a hammer and chisel to break off the head of the rivet. However, these methods may be more likely to cause damage to the rivet or the surrounding area.

Using a drill bit
Removing plastic rivets with a drill bit is a simple process, but it requires careful attention to avoid damage to the surface and the drill bit. Firstly, it is important to determine the type of rivet you are dealing with. Most rivets have a small hole in the centre, and you will need a drill bit that is slightly wider than this hole for effective removal. If your rivets do not have an indentation, you will need to create one with a centre punch and a hammer.
Once you have the appropriate drill bit, attach it to your power drill and secure it tightly. Place the drill bit against the centre of the rivet, applying slight pressure to hold it in place. It is important to maintain control over the drill to avoid applying too much pressure, which can cause slipping and potential damage to the surface. Start drilling slowly, listening carefully for the pitch of the drill bit to change as it bites through the shank of the rivet. When you hear this change, ease off the pressure to avoid damaging the material behind the rivet.
For stubborn rivets, you may need to use a grinding tool to wear down the rivet head before drilling. Alternatively, you can use a hammer and chisel to break off the head of the rivet, then drive it through the surface. If you are dealing with curved-head rivets, it is advisable to flatten the head with a file before drilling to make it easier to find the lip and start drilling.
To avoid damage to the drill bit and the surface, you can wrap tape around the drill bit to act as a depth stop. This is especially useful for longer rivets. Additionally, applying lubricant to the end of the drill bit can help it pierce through the rivet without overheating or sustaining damage. Remember to always wear safety glasses when drilling to protect your eyes from sparks and metal fragments.

Using a punch and hammer
Removing plastic rivets may seem challenging, but with the right tools and techniques, it can be done efficiently. Here's a comprehensive guide on using a punch and hammer to remove plastic rivets:
Prepare the Work Area and Gather the Right Tools
Before starting, ensure your workpiece is securely clamped or fastened to prevent unnecessary movement. This step is crucial for stability and precision during the removal process. Wear safety goggles and gloves to protect yourself from any flying debris. The essential tools you will need for this process are a punch, a hammer, and, optionally, a drill.
Punching a Dent
Select a punch that is appropriately sized for the plastic rivets you are working with. Place the punch in the center of the rivet and hold it firmly in place. Using your hammer, strike the end of the punch with enough force to create a small dent in the center of the rivet head. Be cautious not to miss the punch and accidentally strike your hand. You may need to strike the punch multiple times to create a deep enough divot.
Drilling Through the Rivet (Optional)
If you choose to use a drill, select a drill bit that matches the size of the divot made by the punch. Lubricate the drill bit with cutting fluid or cutting oil to ensure smoother drilling and prolong the life of your bit. Drill at a steady speed, maintaining pressure, and pierce through the rivet.
Removing the Rivet with the Hammer and Punch
With the rivet head removed or punched through, you can now use the hammer and punch to drive the rivet out. Place the punch against the rivet and gently tap it with the hammer to push the rivet out of the hole. Be careful not to use excessive force, as this may damage the surrounding materials.
Additional Tips
- If you are dealing with stubborn rivets, you may need to grind off the head of the rivet before attempting to punch or drill through it.
- Always choose a hammer of the right size and weight for precision and accuracy.
- For delicate workpieces or precision applications, consider using a drill with a dedicated removal tool to minimize damage.
- Remember to collect all rivet fragments to prevent potential damage or injury.

Using a pick tool
To begin, place the pick under the head of the rivet at a 90-degree angle. Apply pressure upwards on the head of the rivet with the pick while turning it with a screwdriver. This will help to loosen the rivet and pop it out. If the rivet is difficult to turn, try using a very small flat-blade screwdriver with a light touch to avoid applying too much pressure.
Another technique is to use the pick to lift the centre pin of the rivet. This will allow you to push or pull the rivet out. If you are prying against a painted surface, it is recommended to slip a piece of cardstock under the tool to prevent scratches.
For stubborn rivets, you can also use a hammer and punch to create a small dent in the head of the rivet. This will provide a grip for the drill bit to remove the rivet. Always wear safety glasses and gloves when removing rivets to protect your eyes and hands from flying debris.

Frequently asked questions
Removing a rivet is simple if you have the right tools. For smaller rivets, use a drill bit to drive through the surface. For stubborn rivets, grind off the head of the rivet, then bore through it. You could also use a hammer and chisel to break off the head of the rivet.
If you need to remove a plastic rivet without breaking it, you can use a plastic trim removal tool to pry it out. You can also use a set of small pick tools to help grab any leftover pieces.
Plastic rivets are used as permanent fasteners that provide secure joints. They are also used to join workpieces together, creating a tamper-proof panel with a clean, smooth finish.
Plastic rivets are typically installed by pushing them into a panel hole by hand. Some plastic rivets, such as expanding push rivets, require you to push the head in, causing the grommet to expand for a tight fit.
Some common types of plastic rivets include push-in rivets, removable push rivets, and expanding push rivets.
