Extract a Broken Bolt Without Drilling
Heat the Bolt to Loosen the Threads
Heat the broken bolt with a propane torch, keeping the flame moving to prevent the bolt from becoming too hot. When the bolt is hot enough, it will expand and the threads may loosen.
Insert a Screw Extractor Bit
Using a drill, insert a screw extractor bit into the broken bolt head. Make sure the bit is firmly inserted, or it may slip and cause injury.
Twist to Remove the Bolt
Using the drill, twist the screw extractor bit in a counter-clockwise motion. This should easily remove the broken bolt. Be careful not to apply too much pressure as this can cause further damage to the bolt.
Additional Tips and Tricks
Use a Center Punch: Before attempting to remove a broken bolt with a drill bit, you should always use a center punch to create a divot in the center of the bolt. This will help keep the drill bit centered and make it easier to drill into the broken bolt.
Use WD-40: WD-40 can be used to help loosen the broken bolt and make it easier to remove. Once the WD-40 has been applied, let it sit for a few minutes before attempting to remove the broken bolt with a drill bit.
Use the Right Drill Bit: When attempting to remove a broken bolt with a drill bit, it is important to use the right size drill bit. The drill bit should be slightly larger than the broken bolt, so that it can easily drill into the bolt.
Use a Hammer: If the broken bolt is still stuck in place after drilling, you can use a hammer to tap the drill bit around the broken bolt. This will help loosen the bolt and make it easier to remove.
Use a Socket Wrench: If a drill bit is not working, you can use a socket wrench to try and remove the broken bolt. This should only be done as a last resort, as it can damage the broken bolt.
Frequently Asked Questions
What kind of drill bit should I use to remove a broken bolt?
To easily remove a broken bolt with a drill bit, you should use the following drill bits:
- High-Speed Steel (HSS) – HSS drill bits are the most commonly used drill bits and are suitable for most drilling applications. They are strong and durable and are able to withstand high temperatures.
- Carbide-Tipped – Carbide-tipped drill bits are extremely hard and durable. They are designed for drilling into hard materials such as cast iron, steel, and stainless steel.
- Cobalt – Cobalt drill bits are designed for drilling into tough metals. They are made of a combination of cobalt, molybdenum, and tungsten, which makes them ideal for drilling through hardened steel.
When choosing a drill bit, it is important to select one that is the correct size and type for the job. If the drill bit is too small, it will not be able to remove the broken bolt. If the drill bit is too large, it may damage the surrounding material.
