Drilling into brick is an essential skill for any homeowner or DIY enthusiast. Whether you’re hanging decor, installing shelves, or mounting fixtures, knowing how to properly drill into brick can save you time, money, and frustration. In this comprehensive guide, we’ll cover everything you need to know about drilling into brick, including the tools and materials you’ll need, the proper techniques to use, and how to avoid common mistakes.
Types of Brick Walls
Before we dive into the specifics of drilling into brick, it’s important to understand the different types of brick walls you may encounter. Indoor brick walls are typically found in older homes and are often used for decorative purposes. These walls are usually thinner and more delicate than outdoor brick walls, which are designed to withstand the elements and provide structural support.
Outdoor brick walls are typically thicker and more durable than indoor walls. They are often used for foundations, exterior walls, and landscaping features. When drilling into outdoor brick walls, you’ll need to use stronger tools and techniques to ensure a secure hold.
Before you start drilling, you need to know the difference between brick and mortar.
Brick vs. Mortar
Another important distinction to make when drilling into brick is the difference between drilling into the brick itself and drilling into the mortar between the bricks. Bricks are made from clay that has been fired in a kiln, resulting in a hard, dense material. Mortar, on the other hand, is a mixture of cement, sand, and water that is used to hold the bricks together.
When drilling into brick, you’ll need to use a masonry drill bit that is specifically designed to handle the hardness of the brick. Mortar, however, is softer and more porous than brick, so you may be able to use a regular drill bit or a smaller masonry bit.
Tools and Materials Needed to Drill Into Brick
To successfully drill into brick, you’ll need the following tools and materials:
Hammer drill: A hammer drill is a specialized tool that combines the rotating action of a drill with a hammering action. This allows the drill bit to break through the hard surface of the brick more easily.
Masonry drill bits: Masonry drill bits are designed specifically for drilling into brick, concrete, and other masonry materials. They have a carbide tip that can withstand the high heat and friction generated by drilling into these hard surfaces.
Safety glasses: Always wear safety glasses when drilling into brick to protect your eyes from dust and debris.
Dust mask: Drilling into brick can generate a lot of dust, so it’s important to wear a dust mask to avoid inhaling it.
Pencil or marker: Use a pencil or marker to mark the spot where you want to drill.
Measuring tape: Use a measuring tape to ensure that your holes are evenly spaced and at the correct height.
Vacuum or compressed air: Use a vacuum or compressed air to clean out the hole after drilling to remove any dust and debris.
Anchors or screws: Depending on what you’re hanging or mounting, you’ll need the appropriate anchors or screws to secure it to the brick.
How to Drill Into Brick Wall: Full Guide
1. Preparing to Drill
Before you start drilling into brick, there are a few important steps you should take to ensure your safety and the success of your project.
First, always wear safety gear, including safety glasses and a dust mask. Drilling into brick can generate a lot of dust and debris, which can be harmful if inhaled or get into your eyes.
Next, choose the right drill bit size for your project. Masonry drill bits come in a range of sizes, so make sure to select one that is appropriate for the size of the hole you need to drill and the size of the anchor or screw you’ll be using.
Mark the spot where you want to drill with a pencil or marker. Use a measuring tape to ensure that your holes are evenly spaced and at the correct height.
Finally, make sure that your hammer drill is in hammer mode. Most hammer drills have a switch that allows you to toggle between regular drilling mode and hammer drilling mode. When drilling into brick, you’ll want to use hammer mode to deliver the extra force needed to penetrate the hard surface.
2. Drilling Technique
Now that you’re prepared to drill, it’s time to focus on your technique. Proper drilling technique is essential for achieving a clean, precise hole without damaging the brick or your tools.
Start by holding the drill perpendicular to the wall. This will ensure that your hole is straight and even. If you hold the drill at an angle, your hole may end up slanted or misaligned.
Begin drilling at a slow speed with light pressure. Let the drill bit do the work, and avoid applying too much pressure, as this can cause the drill bit to overheat or break.
As you drill, gradually increase the speed and pressure. If you’re using a hammer drill, you should feel the hammering action kick in as you apply more pressure.
Continue drilling until you’ve reached the desired depth. Most masonry anchors require a hole that is at least 1 inch deep, but refer to the manufacturer’s instructions for specific requirements.
3. Cleaning the Hole
After you’ve finished drilling your hole, it’s important to clean out any dust and debris before inserting your anchor or screw. This will help ensure a strong, secure hold.
Use a vacuum or compressed air to blow out the hole. If you don’t have access to these tools, you can also use a small brush or pipe cleaner to manually remove debris.
Make sure the hole is completely clean and dry before proceeding. Any remaining dust or moisture can weaken the hold of your anchor or screw.
4. Installing Anchors or Screws
With your hole drilled and cleaned, it’s time to install your anchor or screw. The type of anchor or screw you use will depend on the weight and type of item you’re hanging or mounting.
For lightweight items like picture frames or small shelves, a simple plastic anchor and screw may suffice. These anchors expand as the screw is tightened, creating a secure hold in the brick.
For heavier items like large shelves or televisions, you may need to use a more heavy-duty anchor, such as a sleeve anchor or wedge anchor. These anchors are made of metal and are designed to handle heavier loads.
Refer to the manufacturer’s instructions for specific installation requirements, but in general, you’ll want to insert the anchor into the hole and then tighten the screw until it is flush with the surface of the brick.

How to Drill Into Brick Without a Hammer Drill
If you don’t have access to a hammer drill, you can still drill into brick using a regular drill and masonry bits. However, drilling into brick without a hammer drill can be more challenging and time-consuming.
To drill into brick with a regular drill, start by selecting a masonry bit that is appropriate for the size of the hole you need to drill. Masonry bits for regular drills typically have a more pronounced tip and a slightly different design than those for hammer drills.
Mark your drilling spot and begin drilling at a slow speed with firm pressure. You may need to apply more pressure than you would with a hammer drill to get the bit to penetrate the surface of the brick.
As you drill, periodically remove the bit from the hole and clear away any dust and debris. This will help prevent the bit from overheating and extend its lifespan.
Be patient and take breaks as needed. Drilling into brick with a regular drill can take longer and require more physical effort than drilling with a hammer drill.
How to Drill Into Brick Without Cracking It
One of the most common concerns when drilling into brick is cracking or damaging the brick. While some minor chipping or flaking is normal, there are steps you can take to minimize the risk of cracking.
First, always use the correct drill bit for the job. Masonry bits are specifically designed to handle the hardness of brick and other masonry materials. Using the wrong type of bit or one that is too large can increase the risk of cracking.
Second, avoid drilling too close to the edges or corners of the brick. Bricks are more susceptible to cracking near the edges, so it’s best to keep your holes at least 1 inch away from the edge of the brick.
Third, consider using a template or guide to ensure precise drilling. A template can help you drill straight, even holes and avoid putting too much pressure on any one spot.
How to Drill Into Mortar
Drilling into mortar is similar to drilling into brick, but there are a few key differences to keep in mind. Mortar is softer and more porous than brick, which means you may be able to use a regular drill bit or a smaller masonry bit.
When drilling into mortar, it’s important to choose the right drill bit, mark your drilling spot, and wear safety gear just as you would when drilling into brick. Begin drilling at a slow speed with gentle pressure, gradually increasing the speed and pressure as you drill. Once you’ve reached the desired depth, remove the drill bit and clean out the hole using a vacuum, compressed air, or a small brush.
When installing anchors or screws into mortar, keep in mind that mortar is not as strong as brick, so it may not be suitable for heavy-duty applications. Always assess the condition of the mortar and the weight of the item you plan to hang or mount before proceeding.
Tips And Tricks
Here are a few additional tips and tricks to keep in mind when drilling into brick:
- For larger holes, consider drilling a pilot hole first. This will help guide your masonry bit and reduce the risk of cracking or chipping.
- If you need to drill multiple holes in a row, use a template or guide to ensure even spacing and straight holes.
- Avoid drilling too close to any cracks or damage in the brick, as this can increase the risk of further cracking or crumbling.
- If your drill bit starts to overheat or smoke, take a break and let it cool down before continuing. Overheating can damage the bit and increase the risk of injury.
- To extend the life of your masonry bits, consider lubricating them with a small amount of oil before drilling. This can help reduce friction and heat buildup.
Common Mistakes to Avoid
Even with the best techniques and tools, drilling into brick can be challenging. Here are a few common mistakes to avoid:
- Using the wrong type of drill bit. Always use a masonry bit when drilling into brick, and make sure it is the appropriate size for your project.
- Failing to wear safety gear. Drilling into brick can generate a lot of dust and debris, so always wear safety glasses and a dust mask to protect yourself.
- Applying too much pressure. Let the drill bit do the work, and avoid applying too much pressure, as this can cause the bit to overheat or break.
- Drilling too close to edges or cracks. Bricks are more susceptible to cracking near the edges, so keep your holes at least 1 inch away from the edge of the brick.
