The Buying Guide 

If you want to get the appropriate drill bit for drilling out broken bolts, there are some factors you should consider. In this section, we are going to point out and discuss them in brief.

I) Sturdiness

Drill bits needed for this job have to be very sturdy, which depends on the materials used in their construction. We recommend that you go for bits made out of high-speed steel.

Then, cobalt or titanium nitride coating would help in boosting the bit’s longevity.

II) Split Point

If your bits have 135-degree split points, you can expect the drilling operation into the broken bolt or screw to be an effortless affair.

III) The Brand

Certain brands have an almost perfect record of producing high-quality drill bits. These are the ones that you should go for, and they include DEWALT, Irwin, Neiko, Bosch, and OEMTools.

These brands do not compromise on the quality of construction of their products.

IV) The Flute Length

The length will determine the ease with which you will get the bolt chips that you are drilling out of the hole. The appropriate length would ensure that your bit can evacuate chips without packing them inside the flutes.

FAQs

Before we conclude, we will list some frequent queries and their responses. We hope that you can learn something from this brief Q&A.

Q: What does a drill bit do on an extractor?

A: It helps in removing a screw whose head has been stripped. As you attempt to turn the screw’s head and there is no friction, the screw won’t turn. Therefore, the drill bit will create threads on the screw, and the extractor will remove it by turning the screw in the opposite direction of the threads.

Q: What factors should I focus on as I search for the ideal drill bit for drilling out broken bolts?

A: The main aspects to pay attention to include the construction quality, split points, the brand, the flute length, and the warranty service.

Q: Do all drill bit sets come with a box?

A: Most of them do, and the box helps with storage, transportation, and overall organization of the tools.
