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.
