In this guide, I’ll take you on a tour of black oxide drill bit types and applications to better understand their usage.
Black oxide drill bits are a dark black color and are produced by coating a magnetite (Fe3O4) layer with HSS.
In general, black oxide drill bits are multi-purpose drill bits and can be used on various materials, such as stainless steel, copper, wood, aluminum, and cast iron. They are a great option for both wood and metal. They’re a popular choice for those who need to drill regularly.
Let’s dig into this now.
What are Black Oxide Drill Bits Used For?
Black oxide drill bits are popular among professionals and homeowners for various drilling projects. Here’s a look at some of their most popular uses:
- Drilling through Tough Materials: Black oxide drill bits are perfect for drilling through tougher materials, such as stainless steel and cast iron.
- Lower-speed Applications: Due to their lubricity, black oxide drill bits are ideal for lower-speed applications. This can help to reduce friction and heat build-up.
- Improved Durability: The black oxide coating helps improve the drill bit’s durability, as well as its resistance to wear.
When choosing the right black oxide drill bit for your needs, it’s important to consider the type of material you’ll be drilling through. HSS black oxide drill bits are a good choice for general-purpose drilling applications, while carbide black oxide drill bits are better suited for tougher applications.
Be sure to check out various ranges of black oxide drill bits today.
Range of Black Oxide Drill Bits
- Pneumatic: The most common type, pneumatic black oxide drill bits, uses compressed air to create the force for penetration.
- Hydraulic: A less common type, hydraulic black oxide drill bits use a pressurized liquid to create the required force.
- Electric: The least common type, electric black oxide drill bits, uses an electric motor to generate the necessary force.
There are 3 main types of black oxide drill bits based on size:
- Standard: Standard black oxide drill bits are the most common type and are typically used for general-purpose drilling applications.
- Metric: Metric black oxide drill bits are designed for use with metric-sized drill bits.
- Fractional: Fractional black oxide drill bits are designed for use with fractional-sized drill bits.
There are 2 main types of black oxide drill bits based on material:
- HSS: HSS black oxide drill bits are the most common type and are made of high-speed steel.
- Carbide: Carbide black oxide drill bits are designed for tougher drilling applications. They are also more expensive than HSS black oxide drill bits.
They come in various dimensions ranging from 1/16”, 5/64”, 3/32”, 7/64”, 1/8”, 9/64”, 5/32”, 11/64”, 3/16”, 13/64”, 7/32”, 15/64”, ¼”, 5/16”, 3/8”, ½”.
How to Use Black Oxide Drill Bits?
Using black oxide drill bits is relatively simple and can be done by following these straightforward steps.
- First, you’ll need to choose the right black oxide drill bit for your needs.
- Next, you’ll need to attach the drill bit to your drill.
- Once the drill bit is attached, you can begin drilling through your material. Be sure to drill slowly and apply moderate pressure to avoid overheating the drill bit.
- When you’re finished drilling, remove the drill bit from your drill and clean off any black oxide that has accumulated on the surface.
Be sure to follow these steps to ensure proper use. With proper care, your black oxide drill bits will last for many years.
Difference Between Black Oxide and Other Drill Bits
When it comes to bits, there are a few different types that you can choose from. each type has its own set of benefits and drawbacks. Black oxide drill bits are one type of drill bit that offers a few unique benefits.
Here are some of the key differences between black oxide drill bits and other types of drill bits:
- The black oxide drill bits are designed to resist corrosion. This means that they will last longer and perform better in corrosive environments.
- These drill bits are designed to stay sharper for longer. You can use them more frequently without worrying about them becoming dull.
- Finally, black oxide drill bits are less likely to cause sparking when used in high-speed applications. This makes them safer to use and helps to prevent accidents.
The efficiency of black oxide drill bits varies depending on the quality of the drill you choose and your drilling purposes in terms of materials. To simplify your drilling project, pick up a black oxide drill bit.
