Buying Guide to The Perfect Drill Bit for Steel i Beam

Due to the wide variety of brands available in the market, you may have a hard time and use a lot of time finding something that meets your drilling needs. However, you may narrow down your search by paying attention to some key issues as we shall highlight in the section below:

I) Material

The material used in putting the piece together will determine its performance and efficiency for the task at hand. Common materials used in making these units include High-speed steel (HSS), carbide, and cobalt.

All the materials are distinct and have their set of pros and cons. For example, carbide is perfect for drilling through-hardened steel, but it is too brittle and may break apart halfway through the operation.

II) Bit Design

Here, we mostly look atthe bit’s flute design as it will affect the kind of holes that you will end up with. Further, it will also tell you if you’ll be having flying objects during the operation, which is something that everyone tries to avoid.

You get two designs to choose from, parabolic and 30-degree designs, with the latter perfect for rigid surfaces such as the steel I-beam.

III) The Coating

The coating affects the unit’s durability and the kind of performance that it will deliver. A coated unit will be protected from rust and corrosion and serve you for longer. The most common coatings that you’ll find include black oxide and TiCN.

IV) Length

When it comes to drilling through tough materials, a shorter bit will serve you well due to its rigidity. If you use a longer unit in a tough operation, it may break before you are done with the project.

V) Angle

The normally accepted angle for drill bits is 118-degrees but for more efficient and faster drilling into your steel I-beam, you should go for a 135-degree unit.

FAQs on the Best Drill Bit for Steel I-Beam

If we left out any crucial part of the topic, we hope to cover it in this section containing some of the common queries on the accessory.

Q: Should I sharpen my bit regularly?

A: Yes, you should as it is a creative way of boosting its durability. Even if you are not familiar with how the process is done, there are many online tutorials to give you all the guidance you need.

Q: Which one is more effective in drilling through my Steel I-Beam between cobalt and titanium bits?

A: Although both units are designed to cut through-hardened steel, cobalt units are too expensive, and not everyone can afford them. So, our advice is that you go for a cobalt bit with titanium coating, and no surface will be too tough to drill through.

Q: Is the length of the bit an important factor to look out for?

A: Yes, it is, and it will determine the kind of drilling performance that the unit will give in the long run. When dealing with tough surfaces such as the steel I-Beam, a shorter bit is the best picksince it is rigid enough to prevent breakage during use.

Other than that, all the products are well-made, have a convenient 3-flat shank design and come in a storage box for convenient storage.
