How to Drill Through a Broken Drill Bit
Step 1: Set the Workpiece in a Vise
Secure the workpiece in a vise by tightening the jaws around the piece. Make sure it is firmly secured so that it won’t move when you start to drill.
Step 2: Secure the Broken Drill Bit
Position a pair of locking pliers around the broken drill bit. Use the pliers to secure the broken drill bit in place so that it won’t move when you start to drill.
Step 3: Select and Affix a Drill Bit
Choose a drill bit that is slightly wider than the broken drill bit. Attach the drill bit to the drill and make sure it is securely fastened.
Step 4: Drill Through the Broken Drill Bit
Start the drill and slowly begin to drill through the broken drill bit. Make sure to keep the drill bit straight and move it at a steady speed.

Frequently Asked Questions
What Type of Drill Bit Should I Use to Remove a Broken Drill Bit From Steel?
To remove a broken drill bit from steel, you should use a carbide bit with a two-flute design. The two-flute design helps reduce the amount of heat generated, which helps prevent further damage to the steel. The carbide bit is designed to easily break through the steel and remove the broken bit.
What Safety Precautions Should I Take When Removing a Broken Drill Bit from Steel?
- Wear Appropriate Safety Gear: Wear safety glasses, ear protection, gloves, and a dust mask to protect yourself from flying debris.
- Use the Proper Tools: Use the right tools for the job, such as a drill press, vice, or hammer and chisel. Avoid using pliers or other makeshift tools.
- Secure the Steel: Secure the steel in a vice or other secure structure to prevent it from moving while you are working.
- Be Careful of Heat: If using heat to remove the bit, be sure to use a low temperature and keep the flame away from the bit to prevent it from becoming too hot.
- Be Careful of Sharp Edges: When removing a broken bit, be aware of any sharp edges that may have been created and take care not to cut yourself.
What are the Best Tools to Use When Removing a Broken Drill Bit from Steel?
A broken drill bit can be difficult to remove from steel, so the right tools are essential. The best tools for this job include a center punch, drill, hammer, and locking pliers. The center punch should be used to create a small indentation in the center of the broken drill bit, which allows the drill bit to be held in place while drilling. A hammer should then be used to drive the drill bit into the steel. Finally, locking pliers should be used to grip the broken drill bit and twist it out of the hole.
How do I know if the broken drill bit has been completely removed from the steel?
Signs of Successful Removal:
- No more pieces of the drill bit visible.
- The hold left by the drill bit is no longer visible.
- The steel surface is smooth and even.
- The drill bit can be easily retrieved with a magnet.
Signs of Unsuccessful Removal:
- Pieces of the drill bit are still visible.
- The hold left by the drill bit is still visible.
- The steel surface is rough and uneven.
- The drill bit can not be easily retrieved with a magnet.
What should I do if the broken drill bit is stuck in the steel?
If the broken drill bit is firmly lodged in the steel, you should first try to back it out by turning it counter-clockwise with a pair of pliers. If that doesn’t work, try to remove it with an easy-out tool. If you don’t have an easy-out, you’ll need to use a hacksaw blade to cut the drill bit off, then use an angle grinder to smooth the edges. Finally, use a drill to create a new hole in the steel.
Conclusion
Drill bits stuck in metal can be difficult to remove. However, with the right tools and method, the broken drill bit can be removed easily. Start by using an extractor or a reverse drill bit to try to unscrew the broken bit. If that doesn’t work, try drilling a larger hole around it and then use a pair of locking pliers to remove it. If those methods are unsuccessful, use a die grinder or an angle grinder to cut away the broken bit. Finally, use a magnet to pull out the remains.
