Best Drill Bits for Broken Bolts

Removal of a broken bolt or stud can be extremely difficult. Drills can be used to make holes, but special tools or drill bits are needed to remove broken bolts. Drill bits with reverse gears are known as left-handed drill bits because they work in reverse gear.

It is common practice to use left-handed drill bits in order to remove the bolt without damaging the threads of the hole. It is essential that the bolt or stud be as flat as possible in order for the bit to be drilled in. You can use our guide to find the best drill bits for drilling out bolts if you need to.

For drilling out bolts, what are the best drill bits to use?

Before choosing drill bits for drilling out bolts, there are a few fundamental considerations to keep in mind. As you may already be aware, left-handed drill bits are a necessity, but there are a few other considerations.

  1. Drill bits for removing bolts should be made of high-speed steel, which is extremely durable. In terms of long-term durability, an additional layer of cobalt or titanium nitride is highly beneficial.
  2. Split second. So that you can actually drill into the broken screw or bolt, you need bits with 135-degree split points.
  3. As far as drill bits are concerned, it’s all about the brand. You’re looking for a company that doesn’t compromise on the quality of its products. It’s even better when the product comes with a warranty.

When purchasing a drill bit set, keep in mind how many pieces you will need and whether or not the product comes with a box to keep the bits together and in place. Find out more about left-hand drill bits and choose one that meets your needs right now by searching online.

Bolt-drilling can be exhausting. The task can be difficult, especially if you lack the proper equipment. As a result, the situation can quickly devolve into a frustrating ordeal.

It’s Quick and Easeful:

A good rule of thumb is to start by making sure that the drill bit you’re using is SMALLER than the screw it’s intended to remove. There is plenty of room to drill an adequate hole for extraction in this way. Drill a small hole into the head of the screw or bolt with the cutting diameter. This results in a cone-shaped opening that the extractor head can easily grasp onto. Turn the drill bit over to the extraction side. Drill at a slower speed so the threads can get caught. Remove the bolt or screw in its entirety by screwing or drilling one more time. It’s done! You were able to remove the broken screw in a matter of seconds without causing any harm to your other tools or bits. A powerful steel bit does all the heavy lifting.

A 15-piece NEIKO 10037A left-hand drill bit set featuring SAE (1/16″ – 1/2″) reverse twist M2 HSS steel coated with titanium nitride.

Our company, Neiko, is devoted to tools to the point of obsession. More than an employment opportunity, it’s an irrational desire to push ourselves to our limits. In the beginning, we were told that our goal to make tools that were comparable in quality, design, and function to the “bigger” brands, but at a fraction of the cost, was unrealistic. However, after years and countless hours of dedication to our goal, we were able to master our trade.

Customers have come to associate the Neiko brand with premium value over the past two decades and a half because of this. It is clear to anyone who uses our tools, whether it is a set of impact sockets or step drill bits, how much we care about the quality of what we make.

It is no longer about where we started, but rather where we want to go. It is our goal to continue to grow and not be constrained by the constraints of our current technology. One that not only directs our company but also each of us individually in our daily lives.

The extractors and left-handed (reverse) drill bits in this set are fantastic. As a result, according to some of the reviews, the drill bits were unable to make a dent in whatever they were drilling into. I’d bet my bottom dollar that those who made these claims were unaware that they were supposed to be drilling in reverse. These are something I use on a regular basis in an industrial setting, and they work almost all of the time.
