How to Remove a Broken Drill Bit
Extracting a broken drill bit from metal can prove to be an exasperating endeavor, often testing one’s patience to the limit. Whether you are dealing with a broken bit in a sheet of steel or aluminum, it can feel like an insurmountable task that requires special tools and expertise.
Nevertheless, by employing the appropriate method and exercising a bit of patience, it is possible to extract a bit without incurring substantial expenses. Here are some tips to help you get started.
Pulling out a Broken Drill Bit
The first step is to start by drilling more holes around the broken one. Make sure that the new holes are slightly bigger than the existing one and also have sharp edges. This will effectively dislodge any debris that may have become lodged around the bit, ensuring smooth operation and optimal performance.
Utilize a substantial pair of vice grips or pliers to firmly grasp the fragmented piece. You can also use an adjustable wrench to grab it if you don’t have access to larger tools. Make sure to hold the tool securely and do not apply too much pressure. Then, try to twist and turn the drill bit while pulling it out of the metal.
If these methods do not work, use a special extractor tool. This is an attachment that fits into your drill and which has several small pins that help to grip and extract broken bits. Make sure to read the instructions carefully before using this tool as it can be dangerous.
Finally, if all else fails, you may need to ask for professional help. A professional machinist or metal worker can use special tools and techniques to get the broken bit out without damaging the metal. It is always best to seek help from a qualified professional rather than attempt something that could put you or your workpiece at risk.
Wipe the end of the broken bit
Once the broken bit has been removed, it is important to clean up any debris from the end of it. This will help prevent further breakage and also keep your drill bits in good condition. Before returning the broken bit to its storage container, use a cloth or rag to gently wipe away any dirt. This simple step helps maintain cleanliness and ensures the bit is ready for future use.
Clamp a pair of locking pliers onto the broken end
In some cases, the broken bit may be stuck so tightly in the metal that none of the above methods are able to remove it. If this is indeed the situation, you may consider securing a set of locking pliers onto the fractured end. This will help to grip and loosen the bit, making it easier to pull out when combined with one of the other methods listed above.
Rotate the pliers counterclockwise
In order to ensure that the pliers are able to grip and loosen the bit, it is important to rotate them counterclockwise. This will help break up any debris or rust buildup, making it easier to remove. Make sure you use a slow and steady motion when doing this so as not to damage your metal workpiece.
Pull the drill bit out of the material
Now that the bit is loose, it’s time to pull it out of the material. Make sure you hold onto the pliers firmly and use slow, steady pressure when pulling the bit out. You may need to try twisting or turning the bit at this point to further loosen any debris that might be stuck around it. Doing so will help make sure that you don’t leave any of the debris behind when you remove the bit. After successfully pulling out the drill bit, inspect it to make sure that it is in good condition before returning it to its storage container.
Using a Screw Extractor
A screw extractor is a type of tool designed to remove broken screws, bolts and drill bits from metal. It is made up of two components – a cone-shaped bit and an outer collar with a set of flutes. To use it, first you have to determine the size of the bit that needs to be removed. You can do this by measuring the diameter of the bit with a caliper. Once you have the size, select an appropriate screw extractor that matches it.
Now, place the screw extractor in a power drill and insert it into the broken bit or bolt, making sure to keep it centered. Next, slowly increase the speed of your drill until you feel resistance. At this point you may have to press down on the drill bit to keep it in place. Finally, turn the extractor counterclockwise and apply pressure as you do so. The bit should start to come out gradually until eventually it is removed from the metal.
You can also try using a hammer to remove broken bits from metal. To do this, simply place the head of the hammer against the bit and tap it a few times to loosen it. Then, use an adjustable wrench or pliers to firmly grasp the broken bit and pull it out of the metal. This method is most effective if you have access to both sides of the piece of metal.
Put on a pair of safety glasses
It is important to wear protective eyewear. This will help protect your eyes from any debris that may fly up when using a hammer or power drill. It is also recommended that you wear gloves and long sleeves to protect your hands and arms from sharp edges. Additionally, always ensure that you are working in a well-ventilated area to avoid the inhalation of any metal particles that could be released when removing a bit.
If you are unable to extract it yourself, it is best to seek help from professionals who have experience in this type of work. Professionals will be able to safely and effectively remove the broken bit without causing any further damage. They may also be able to recommend a better tool or method for getting it out of metal.
Chisel off any jagged edges
After extracting the bit, carefully examine the piece for any sharp or uneven edges. Use a chisel or file to carefully remove them. This will ensure that no sharp points remain on the edge of your metal and make it safe to handle. Before utilizing the metal for any other tasks, it is advisable to thoroughly remove any lingering dust or debris by gently wiping it with a damp cloth. This will ensure optimal cleanliness and prepare it for its intended purpose.
Getting a broken bit out of metal can be a difficult task, but with the right tools and knowledge it can be done properly. The tips in this guide should help you effectively remove a broken bit from metal without causing any damage. Just remember to always wear safety glasses and gloves when working with power tools or hammers, and never hesitate to seek help from professionals if needed.
Create a divot on the bit with a center punch
If the broken piece remains lodged in the metal, you can make a small indentation on it using a center punch. This technique will facilitate the removal process and provide a better grip for pliers or an adjustable wrench when attempting to extract it. To do this, place the tip of the center punch onto the edge of the broken bit and tap it with a hammer. This will create a small divot in the bit that should provide enough grip for you to pull it out. Wear safety glasses when performing this task, as debris can easily fly up and cause injury.
Insert a smaller drill bit into a power drill and apply cutting oil
This method offers a practical solution, preserving the original intent while enhancing the overall quality of the writing. Start by inserting the smaller bit into the drill and then apply some cutting oil to the area surrounding the bit for lubricating it as you attempt to remove it from the metal.
Drill about 1⁄4 inch into the bit
After applying the oil, carefully drill approximately 1⁄4 inch into the damaged bit. This will create a space between the two bits that should provide enough room for you to get a tool around it and pull it out.
Insert a tap extractor
After creating a gap between the two pieces, employ an adjustable wrench to securely grip the fractured bit and attempt to extract it from the metal. If it is still stuck, you can also try using a tap extractor. Insert the tap extractor onto the bit and slowly turn it counterclockwise while applying pressure until you feel some resistance.
Turn the extractor counterclockwise
Continue turning the extractor counterclockwise a few more times, and eventually, the broken bit should be successfully removed. Wear safety glasses during this process as well, as flying debris can easily cause injury. Once the broken bit has been removed from the metal, you can inspect it for any damage or jagged edges. If present, use a chisel or file to remove them before using the piece of metal for any other purpose.
Preventing Future Breaks
Now it’s important to practice a few preventive measures so that you don’t have to go through the same process again.
First, use a bit with the right size and shape for the job at hand. If you are unsure, ask an expert or look up what type of bit is best for the material you are drilling into.
Next, use a drill stop or depth collar to control how deep your drill bit goes. This will prevent it from getting stuck in too far and breaking off inside the metal.
Lubricate your drill bit before you use it
This will reduce friction and make for a smoother drilling experience. It can also make it easier to remove the broken bit from the metal later on, as the lubricant will create less drag between the two surfaces. Use a high-temperature grease or WD-40 spray for best results. Be sure to apply a generous amount of lubricant before you begin drilling.
Insert the drill bit as far into the drill as possible
This will help you get a better grip on it and make sure that when you’re removing it, you don’t end up damaging the surface of the material. If you can’t get a good hold of the drill bit, try using a pair of pliers or some other type of gripping tool.
Bring the drill up to speed slowly
When operating a drill, it is crucial to proceed gradually and increase speed gradually. It is essential to maintain a balance between caution and efficiency, ensuring precision and safety in the process. This will help you avoid the risk of breaking the bit off in the metal. [1]
