Introduction

Drilling through metal, wood or other materials can sometimes result in a broken drill bit. It is not only frustrating but also potentially dangerous if not removed properly. This article will guide you through three simple methods to remove a broken drill bit from different surfaces safely and efficiently.

Method 1: Use Pliers

Step 1: Disconnect Power Source

Before starting, ensure that the power source for your drilling equipment is disconnected to avoid accidental turning on while working on the broken bit.

Step 2: Choose the Right Pliers

Select pointed needle-nose or locking pliers based on your preference and the size of the broken drill bit.

Step 3: Firmly Grip the Broken Drill Bit

Using the pliers, firmly grip any exposed portion of the broken drill bit. Apply pressure and twist counterclockwise, ensuring not to further damage the hole you’ve drilled or jam the bit deeper.

Step 4: Dispose of the Broken Drill Bit

Once the broken piece is removed, make sure to safely dispose of it and replace it with a new bit before proceeding with your project.

Method 2: Use a Left-Handed Drill Bit

Step 1: Select a Left-Handed Drill Bit

Choose a left-handed drill bit slightly smaller than your broken one. A left-handed drill bit will turn counterclockwise when drilling, which helps remove the broken piece.

Step 2: Create a Pilot Hole

Using a center punch, create a small indentation in the center of the broken drill bit to guide your left-handed drill bit.

Step 3: Drill Slowly and Carefully

Insert the left-handed drill bit into your power drill. Slowly start drilling into the broken piece at a low RPM setting. As you continue drilling, maintain steady pressure and keep an eye on any movement or progress made in removing the broken bit.

Step 4: Retrieve the Broken Piece

Once enough of the broken piece is loosened, carefully use pliers to grip it and twist counterclockwise, removing it from the material.

Method 3: Use a Screw Extractor

Step 1: Select the Right Sized Screw Extractor

Choose a screw extractor that closely matches the size of your broken drill bit.

Step 2: Create a Pilot Hole

Use a center punch to create a small indentation in the center of the broken drill bit.

Step 3: Drill and Tap Your Hole

Using a power drill, create a small hole deeper into the broken bit. Then, insert your screw extractor into this hole. Tap it lightly with a hammer to ensure proper seating.

Step 4: Extract the Broken Bit

Turn the screw extractor counterclockwise using an adjustable wrench or T-handle. Applying constant pressure should loosen and remove the broken piece without causing further damage.

Conclusion

Having a broken drill bit is never ideal, but with these three simple methods, you should be able to remove the broken pieces safely and quickly. Remember always to disconnect your power tools from their power source before attempting any repair, and be sure to wear appropriate safety gear while working with tools.
