Methods for Drilling Out a Broken Drill Bit

When it comes to removing a broken drill bit, there are several methods you can employ. Each method has its own advantages and considerations, so it’s important to choose the one that suits your specific situation. Here are three popular methods for drilling out a broken drill bit:

Method 1: Using a Left-Handed Drill Bit

Using a left-handed drill bit is one of the most common methods for drilling out a broken drill bit. These specialized drill bits have a reverse cutting pattern, which means they turn counterclockwise. The idea behind this method is that as you drill into the broken drill bit, the reverse cutting pattern creates torque that helps to loosen the broken piece, making it easier to remove.

To use a left-handed drill bit, follow these steps:

1. Secure the workpiece in a vice or clamp to keep it steady.
2. Select a left-handed drill bit that is slightly smaller than the broken drill bit.
3. Carefully position the drill bit at the center of the broken piece.
4. Set the drill to reverse and apply gentle pressure as you begin drilling.
5. Monitor your progress and stop drilling once the broken piece starts to loosen.
6. Use pliers or a similar tool to extract the broken drill bit.

While this method can be effective, it’s important to note that it may not work in all situations. If the broken drill bit is lodged too tightly or the material is especially hard, you may need to explore alternative methods.

Method 2: Using a Screw Extractor

If the left-handed drill bit method fails or is not suitable for your situation, using a screw extractor is another option to consider. A screw extractor is a specialized tool designed to grip the broken piece and rotate it counterclockwise as you turn it with a wrench or drill. It’s important to match the size of the screw extractor to the size of the broken drill bit for optimal results.

Follow these steps to use a screw extractor:

1. Choose an appropriate-sized screw extractor for the broken drill bit.
2. Using a drill or wrench, carefully turn the screw extractor counterclockwise to embed it into the broken drill bit.
3. Apply consistent pressure as you turn the screw extractor to gradually loosen the broken piece.
4. Once the broken drill bit is sufficiently loosened, use pliers or a similar tool to extract it.

Screw extractors can be highly effective, particularly if the broken drill bit is firmly embedded in the material. However, it’s essential to proceed with caution and ensure you have the appropriate tools and skills to avoid further damage to the workpiece or injury to yourself.

Method 3: Using a Tungsten Carbide Drill Bit

If the previous methods don’t yield the desired results, using a tungsten carbide drill bit is another viable option. Tungsten carbide is an extremely hard and durable material that can effectively drill through hardened steel, making it suitable for removing broken drill bits stuck in tough materials.

To use a tungsten carbide drill bit, adhere to the following steps:

1. Select a tungsten carbide drill bit that matches the size of the broken drill bit or is slightly larger.
2. Ensure the workpiece is securely clamped or held in place to prevent movement during drilling.
3. Apply cutting fluid or lubricant to the area to reduce heat and friction.
4. Start drilling at a low speed and gradually increase to maintain control and prevent overheating.
5. Monitor your progress and stop drilling once you’ve reached the broken piece.
6. Gently pry or extract the broken drill bit using pliers or a similar tool.

Using a tungsten carbide drill bit requires patience and precision, as excessive force or incorrect drilling techniques can lead to further complications. It’s crucial to prioritize your safety and take the necessary precautions when employing this method.
