Best Drill Bits for Drilling Out Broken Bolts(Easy Checklist)

Top Drill Bits Top Drill Bits Best for Drilling Out Broken Bolts

You will be shocked to know how common of a problem broken bolts are. One may think that a bolt is made of strong metal, and there is no way it will break. But various reasons may cause breakage in bolts after they are fitted in place. Sometimes the breakage may occur in the middle of fitting the bolt. When bolt snaps, the threads on the fractured end may be entirely stripped, requiring drilling. Overtightening the bolt is a common cause of this. If the bolt is stuck where it can’t be removed, it must be drilled out. There are several different bolt extractors on the market today. All of the items are competitive in terms of features, build quality, applications, and costs. Because this is not a tool that you buy every day, and you must choose the right product to remove broken bolts. Today, we will discuss some of the finest drill bits available for removing broken and stuck bolts.

Is it possible to drill broken bolts?

Broken fasteners aren’t uncommon, which is why the tool industry has devised several inventive methods for removing broken bolts and studs. Sometimes to pull out a broken bolt, all you need is a hammer and a chisel, as well as a bit of persistence. If the hammer and chisel method fail, you’ll have to attempt drilling the bolt out and extracting it with a bolt extractor. If that doesn’t work, you’ll have to drill the bolt out just shy of the threads in the hopes of removing the remaining parts caught in the threads gently.

Picking this set will make anyone confident as these extractors will not misalign from the bolt easily when you use them with aggressive force, as the extractor features a left-hand design for enhanced gripping force.

The spirals are forced deeper into resistant metals as the tool is spun, making the grip of the bolt extractor stronger. The drill bits are shock-resistant and built to withstand the most extreme situations. They become embedded into the metal if there is high force and high resistance during drilling, allowing them to hold drill bits with more turning power. 

Because the increased distortion helps them grip better, you can drill more precisely with more torque. Keep an adjustable range if any extra force is needed while removing the bolt.

Irwin also provides a compact case to store the drill bits very easily as there is clear labeling on each tool. Included dividers make it simple to organize the drill bits. These are sturdy, high-quality components that will endure for a long time.

How to remove a broken drill bit (Step by Step)

Step-1:

Start by drilling into the bolt that needs extraction. The size of the broken bolt will determine the size of the bit. These drill bits should be smaller than the bolt head or if the head is broken off the bolt body. Drill the tip of the bolt into the exposed bolt’s center top. Turn on the drill and pull the trigger to drive these drill bits right through the metal bolt to a quarter-inch depth.

Step-2:

Now stop drilling and focus on the newly drilled hole. In the cavity formed by the drill, place the bolt extractor on top of the bolt. Using pliers, grasp the top of the bolt extractor and crank it counterclockwise to dig into the bolt. Continue to twist the bolt extractor until the broken bolt’s surface is elevated above the entered point.

Step-3:

After that, put the bolt extractor aside and grasp the broken bolt’s raised tip with the pliers. Twist the bolt counterclockwise until it is removed from the surface.
