What kind of drill bit for cement? - Fix It Cape Town

Drilling into cement can be a challenging task if you don’t have the right tools. Whether you’re mounting fixtures or installing shelves on cement walls, selecting the correct drill bit is key to achieving effective and precise results. In this guide, we will explore the different types of drill bits suitable for drilling into cement, and provide you with tips on how to choose the correct size and design. So, let’s get started!

Understanding the Types of Drill Bits for Cement

When it comes to drilling into cement, not all drill bits are created equal. Cement is a hard material, and using the wrong type of drill bit can result in inefficient drilling, damage to the drill bit, and ultimately, an unsatisfactory outcome. Here are the main types of drill bits suitable for cement:

  1. Masonry Drill Bits: These are specially designed for drilling into hard materials such as concrete, brick, and stone. They have a carbide tip that helps to penetrate the cement and make the drilling process easier. Masonry drill bits are available in various sizes and lengths to suit different drilling needs.

  2. Tile Drill Bits: If you are drilling into cement tiles or other types of ceramic tiles, using a tile drill bit is essential. These drill bits have a spear-shaped carbide tip that prevents cracking and chipping of the tiles during drilling. Tile drill bits are also suitable for drilling into other materials like glass and porcelain.

  3. Diamond Drill Bits: These drill bits are ideal for drilling into extremely hard materials like reinforced concrete. Diamond drill bits have a diamond grit coating that allows them to cut through the toughest surfaces with ease. They are particularly useful for drilling large diameter holes.

How to Choose the Correct Size and Design

Now that you are aware of the different types of drill bits suitable for cement, it’s time to choose the correct size and design for your specific drilling needs. Here are some factors to consider:

  1. Drill Bit Diameter: The diameter of the drill bit determines the size of the hole you will be drilling. Ensure that you choose a drill bit with the appropriate diameter for your project. Measure the size of the wall plug or anchor you will be using and select a drill bit that matches or slightly exceeds that size.

  2. Drill Bit Length: The length of the drill bit is important, especially if you need to drill deep into the cement. Make sure the drill bit is long enough to reach the desired depth without causing any inconvenience or difficulty during drilling.

  3. Flute Design: The flute design of the drill bit affects the speed and efficiency of drilling. The most common flute designs are spiral and straight. Spiral flute drill bits are efficient and provide better chip removal, making them suitable for deeper holes. Straight flute drill bits are more suitable for shallow holes.

  4. Shank Type: The shank of the drill bit is the part that fits into the drill chuck. It’s important to choose a drill bit with a shank that matches the chuck size of your drill. Most drill bits have a round shank, but some may have hexagonal shanks that provide better grip and prevent slipping.

  5. Quality and Durability: Investing in high-quality drill bits is essential for achieving accurate and long-lasting results. Look for drill bits made from high-speed steel (HSS) or carbide, as they are more durable and can withstand the demands of drilling into cement.

Frequently Asked Questions About Cement Drill Bits

Q: Can I use a regular drill bit for drilling into cement?
A: No, regular drill bits are not designed to withstand the hardness of cement and may quickly wear out or become damaged.

Q: How can I ensure a clean and smooth hole when drilling into cement?
A: Opt for drill bits with sharp cutting edges and use light pressure while drilling. Applying excessive force can lead to chipping and rough holes.

Q: How can I prevent the drill from slipping while drilling into cement?
A: Start drilling with a smaller pilot hole and gradually increase the size. This will provide a guide for the larger drill bit and prevent slipping.

Q: Can I use water for lubrication while drilling into cement?
A: Yes, using water as a lubricant can help keep the drill bit cool, prevent overheating, and enhance drilling efficiency.


Selecting the right drill bit is crucial for drilling into cement effectively. By understanding the different types of drill bits suitable for cement, as well as considering the correct size, design, and quality, you can ensure precise and satisfactory results. Remember to use a masonry drill bit or an appropriate specialized drill bit for tile or diamond drilling when working with cement. Follow the provided guidelines, take necessary safety precautions, and enjoy your successful drilling projects!
