Which Colour drill bit for brick? - Fix It Cape Town

Drilling into brick can be a challenging task, requiring the use of a drill bit specifically designed for masonry materials. One important aspect to consider when choosing a drill bit for brick is its color. Different drill bit colors indicate the type of material they are most suitable for, ensuring efficient and effective drilling. In this guide, we will explore the significance of drill bit color and how to identify the right color for drilling into brick.

Why Drill Bit Color Matters

The color of a drill bit indicates the type of coating or treatment it has received, which affects its performance and durability. Different materials require different drill bit characteristics to ensure optimal drilling results. By understanding the significance of drill bit colors, you can avoid using the wrong bit for the job and prevent unnecessary damage or accidents.

Understanding Drill Bit Colors

When it comes to drilling into brick, there are specific drill bit colors to look out for. These colors signify the type of coating or treatment that the drill bit has received, making it suitable for masonry materials like brick.

Here are some common drill bit colors and their meanings:

  1. Black Oxide: Black oxide drill bits have a dark color due to the black oxide coating applied to the tool. This coating improves heat resistance and lubricity, allowing the drill bit to withstand high temperatures. However, black oxide drill bits are not recommended for drilling into brick as they are primarily designed for drilling into wood, plastic, and non-ferrous metals.

  2. Titanium Nitride (Gold): Drill bits with a gold-colored coating are typically made of high-speed steel and coated with titanium nitride. The gold coating increases the hardness and heat resistance of the drill bit, making it suitable for drilling into various materials, including brick. Titanium nitride-coated bits provide improved durability, reduce friction, and extend the life of the drill bit.

  3. Carbide (Silver): Silver-colored drill bits often indicate that they are made of carbide or have a carbide tip. Carbide drill bits are incredibly hard and excel in drilling through tough materials like brick, concrete, and tile. They have excellent heat resistance and can handle high-speed drilling. The carbide tip ensures excellent performance and longevity.

  4. Diamond (Silver): Diamond drill bits are known for their exceptional strength and cutting ability. They are silver in color and contain diamond particles on the tip or edges. Diamond drill bits are specifically designed for drilling into extremely hard materials like granite, porcelain, and tough brick. Their superior cutting power makes them ideal for heavy-duty masonry drilling.

Identifying the Right Drill Bit Color for Drilling into Brick

Now that we understand the significance of drill bit colors, let’s look at how to identify the right color for drilling into brick:

  1. Check the Packaging: Most drill bit sets indicate the type of material they are suitable for on the packaging. Look for drill bits specifically designed for masonry or concrete. These sets often include silver or gold-colored bits, indicating their compatibility with brick.

  2. Read the Product Specifications: If you are purchasing individual drill bits, carefully read the product specifications provided by the manufacturer. They usually mention the recommended materials for each drill bit type. Look for bits labeled for masonry, concrete, or brick drilling.

  3. Ask an Expert: If you are unsure about which drill bit color to use for drilling into brick, reach out to professionals or experienced individuals in the field. They can provide valuable insights and recommendations based on their expertise.


Q: Can I use any drill bit color for drilling into brick?

A: No, not all drill bit colors are suitable for drilling into brick. It is best to use drill bits with silver or gold-colored coatings, such as carbide or titanium nitride. These colors indicate the specific coatings or treatments that make the drill bits ideal for masonry materials.

Q: What happens if I use the wrong drill bit color on brick?

A: Using the wrong drill bit color can result in inefficient drilling, increased wear on the drill bit, and potential damage to the brick. It is crucial to use the correct drill bit color to ensure effective and efficient drilling.

Q: Can I use a black oxide drill bit for brick if I do not have any other options?

A: While it is possible to use a black oxide drill bit for brick, it is not recommended. Black oxide-coated drill bits are primarily designed for drilling into wood, plastic, and non-ferrous metals. Using them on brick may result in reduced drilling efficiency, excessive heat, and premature wear of the bit.


Identifying the right drill bit color is essential for efficient drilling into brick. By understanding the significance of different drill bit colors and their coating or treatment, you can select the best drill bit for masonry materials. Silver or gold-colored bits, indicating carbide or titanium nitride coatings, are the ideal choices for drilling into tough materials like brick. Remember to always check product packaging and consult experts if you are unsure about the appropriate drill bit color for your project.
