It is important to have a range of sizes available, as the size of the broken drill bit will dictate which drill bit is most suitable for this purpose.
To make the removal process easier and safer, it is recommended to use a cutting oil or lubricant. This will help to reduce friction and heat, making it easier to remove the broken drill bit without damaging the surrounding metal.
Lastly, it is important to ensure that you have safety goggles and gloves on hand. These protective measures will help to prevent any potential injuries during the removal process. Additionally, a ruler or measuring tape may be useful for measuring the depth of the broken drill bit or the size of the pilot hole.
Apply Lubricant
Applying a lubricant to the broken drill bit can help loosen it from the metal, making it easier to remove. There are several types of lubricants that can be used for this purpose, including penetrating oils, such as WD-40, or a general-purpose lubricant, like silicone spray. It is important to choose a lubricant that is appropriate for the specific type of metal and drilling situation.
Here are some steps to apply lubricant to the broken drill bit:
- Clean the area around the broken drill bit to remove any dirt or debris that could interfere with the lubricant.
- Shake the lubricant well to ensure it is thoroughly mixed.
- Spray or apply the lubricant directly onto the broken drill bit.
- Allow the lubricant to penetrate the area for a few minutes. This will help to loosen any rust or corrosion that may be binding the broken drill bit.
- Use a pair of pliers or a wrench to gently twist and pull the broken drill bit out of the metal. If it is still stuck, repeat the process of applying lubricant and waiting a few minutes before attempting to remove it again.
Remember to always use caution when working with lubricants and broken drill bits. Wear appropriate safety gear, such as gloves and eye protection, and follow the manufacturer’s instructions for the specific lubricant being used.
Use a Center Punch
A center punch is a tool that can help you remove a broken drill bit from metal. This technique is especially useful if the broken bit is stuck tight and cannot be easily pulled out.
Instructions:
- Start by positioning the center punch directly on top of the broken drill bit.
- Apply steady and firm pressure with a hammer to create a small indentation in the center of the broken drill bit.
- This indentation will allow the center punch to grip the broken bit and provide leverage for removal.
- Once the indentation is created, place the center punch slightly at an angle and tap it gently with a hammer in a counterclockwise direction.
- The counterclockwise force will help to loosen and release the broken drill bit from the metal.
- If necessary, repeat the process by applying more pressure or tapping the center punch at different angles.
Using a center punch can be an effective method for removing a broken drill bit from metal, especially when other methods are not successful. However, be cautious and always wear eye protection when using this technique.

- If the broken drill bit is extremely stubborn, you may need to use a larger center punch or seek professional help.
Drill in Reverse
Using the reverse function on your drill can be an effective and safe way to remove a broken drill bit from metal. This technique is particularly useful when the drill bit is stuck and cannot be unscrewed using conventional methods.
To drill in reverse, follow these steps:
- Ensure the drill is in reverse mode. Most drills have a switch that allows you to change between forward and reverse.
- Secure the metal piece that contains the broken drill bit. You can use clamps or a vice to hold it steady.
- Place the drill bit directly on the broken piece, aligning it with the hole.
- Apply steady pressure as you slowly drill in reverse. The goal is to create enough friction to loosen the broken drill bit.
- If the drill bit is still stuck, try applying some lubricant or penetrating oil to help loosen the grip.
- Once the broken drill bit starts to move, continue drilling until it comes out completely.
- Inspect the hole to make sure no remnants of the broken drill bit remain. If necessary, use a pair of pliers or tweezers to remove any remaining pieces.
Remember to always wear appropriate safety gear, such as safety glasses and gloves, when working with tools and metals. It is also important to use the correct drill bit for the material you are working with and to use a drill that is appropriate for the job.
Use a Screw Extractor
If the broken drill bit is stuck firmly in the metal and other methods have failed, using a screw extractor might be your best option. A screw extractor is a special tool designed to grip onto the broken drill bit and remove it from the metal.
Here are the steps to use a screw extractor:
- Choose the right size screw extractor for your broken drill bit. Screw extractors come in different sizes, so make sure to select one that fits the diameter of your broken drill bit.
- Attach the screw extractor to a drill. Screw extractors are typically used with a power drill, so attach it securely to the chuck of your drill.
- Drill into the broken drill bit. Place the tip of the screw extractor onto the broken drill bit and start drilling slowly in reverse. Apply gentle pressure and increase the speed of the drill gradually.
- Grip the broken drill bit. As you drill into the broken drill bit, the flutes on the screw extractor will start to bite into the metal, providing grip. Continue drilling until the screw extractor has a firm grip on the broken drill bit.
- Remove the broken drill bit. Once the screw extractor has a secure grip, switch the drill to forward motion and slowly pull the broken drill bit out of the metal. If necessary, you can use pliers or a wrench to help twist and remove the broken drill bit.
Using a screw extractor can be an effective method to remove a broken drill bit from metal. However, it requires careful handling of the power drill and appropriate selection of the screw extractor size. If you’re unsure or uncomfortable with using a screw extractor, it’s best to seek professional assistance.
Heat the Metal
Another method to remove a broken drill bit from metal is to heat the metal. This technique works by expanding the metal around the broken drill bit, allowing for easier removal.
Here’s how to do it:
- Choose a heat source such as a propane torch or a heat gun.
- Make sure to wear appropriate safety gear, including heat-resistant gloves and safety glasses.
- Heat the area surrounding the broken drill bit for a few minutes, focusing the heat directly on the metal.
- Once the metal is hot and expanded, quickly cool it down by spraying it with cold water or using compressed air.
- This sudden contraction after the expansion can loosen the grip of the broken drill bit on the metal.
After heating the metal, you can now try removing the broken drill bit using pliers or a screw extractor tool.
Keep in mind that this method may not work for all types of metals, as some metals may be more resistant to heat expansion. Additionally, always exercise caution when working with heat sources and ensure proper ventilation in your work area.
