The Buying Guide for High-Quality Drill Bits for Drilling Out Broken Bolts

If you want to get the appropriate drill bit for drilling out broken bolts, there are some aspects that you have to look out for. In this section, we are going to point out and discuss those factors in brief.

I) Sturdiness

The first thing is that the drill bits for the job have to be very sturdy, and this depends on the materials used in their construction. In this instance, we recommend that you go for high-speed steel material.

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, OEM Tools, and so on.

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

IV) The Flute Length

This 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 on The Appropriate Broken Bolt Drill Bits

Before we conclude, we will give you some of the queries that we faced frequently and their responses. We hope that you can learn something from the brief Q&A session generated.

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