How to Drill Into Brick Like a Pro (A Beginner’s Guide)
Yes, you can absolutely drill into brick. The key is to use the right tools: a hammer drill and a masonry drill bit. For a secure hold, always drill into the solid part of the brick, not the soft mortar joint. Then, insert a wall anchor before your screw.
Have you ever wanted to hang a heavy shelf, a TV mount, or a pretty planter on a brick wall? Many people stop right there. They worry about cracking the brick or making a huge mess.
It can feel like a job only for a professional. But it’s not!
Drilling into brick is a common and very doable DIY project. You just need the right gear and a little bit of knowledge. We are here to help. This guide will walk you through every simple step. You will learn how to drill into brick safely and with confidence. Let’s get started.
Why Would You Need to Drill Into Brick?
Brick walls are strong and look great, both inside and outside your home. But their strength can also make them seem tricky to work with. Here are a few common reasons you might need to drill a hole in brick:
- Hanging Heavy Items: Think floating shelves, large picture frames, heavy mirrors, or a flat-screen TV mount.
- Outdoor Fixtures: Installing house numbers, mailboxes, hose reels, or security cameras.
- Decor and Gardening: Mounting trellises for climbing plants, hanging baskets, or outdoor string lights.
- Home Security: Attaching brackets for security cameras or motion sensor lights.
For any of these jobs, you need a secure anchor point. A simple nail won’t work. Drilling a proper hole is the only way to do it right.
The Golden Rule: Drill the Brick, Not the Mortar
Before you even pick up a drill, you need to know where to drill. You have two choices on a brick wall: the brick itself or the mortar joints between the bricks.
Always aim for the center of a solid brick.
Why? Brick is dense, strong, and provides a much more secure hold for screws and anchors. It’s designed to bear weight. When you drill into brick and insert a proper anchor, it can hold a significant amount of weight safely.
Mortar, on the other hand, is much softer and can be crumbly. It’s just there to hold the bricks together. If you drill into mortar, it can easily degrade over time, causing your anchor to become loose. The last thing you want is for your brand-new TV to fall off the wall!
While drilling into mortar is sometimes easier, it’s a shortcut that isn’t worth the risk for most projects.
Tools and Materials You’ll Need
Having the right tools makes all the difference. Trying to use the wrong equipment will only lead to frustration and poor results. Here’s your checklist.
Your Toolkit:
- Hammer Drill: This is the most important tool. A hammer drill doesn’t just spin; it also punches forward in a rapid hammering motion. This action pulverizes the brick as the bit turns, making drilling much easier. A regular drill will struggle and likely burn out. Many modern cordless drills have a hammer setting, which is perfect for this job.
- Masonry Drill Bits: You cannot use wood or metal bits. You need special masonry bits, which have a tough, carbide tip designed to chew through concrete and brick. They often have a flat, arrow-like head.
- Wall Plugs / Anchors: These are essential. A screw drilled directly into brick will not hold. A wall plug (or anchor) is a plastic or metal sleeve that you insert into the drilled hole. When you drive a screw into it, the plug expands, gripping the inside of the brick tightly.
- Screws: Make sure they are the correct size for your wall anchors. The anchor packaging will usually tell you what screw size to use.
- Tape Measure & Pencil: For marking your spot accurately.
- Spirit Level: To make sure what you’re hanging is perfectly straight.
- Safety Goggles: Non-negotiable. Brick dust and chips can fly out of the hole and cause serious eye injury.
- Dust Mask: Breathing in fine brick dust (silica dust) is harmful to your lungs.
- Shop-Vac or Dust Collector: Highly recommended for keeping your work area clean and capturing dust at the source.
How to Drill Into Brick: A Step-by-Step Guide
Ready to go? Let’s break it down into simple, easy-to-follow steps.
Step 1: Gear Up for Safety
Before you do anything else, put on your safety goggles and dust mask. Drilling into brick creates a lot of fine dust and can send small, sharp fragments flying. Protect your eyes and lungs. This step is quick, easy, and the most important one.
Step 2: Measure and Mark Your Spot
Use your tape measure to find the exact location for your hole. If you’re hanging something that needs multiple screws, like a shelf bracket, use your level to make sure your marks are perfectly horizontal or vertical.
Mark the spot clearly with a pencil or marker. Aim for the center of the brick, staying at least an inch away from any edge to prevent cracking.
Pro-Tip: Place a small piece of masking tape over your mark. This gives you a better surface to write on and helps prevent the drill bit from “walking” or slipping when you first start drilling.
Step 3: Select the Right Drill Bit and Anchor
This part is crucial. Your drill bit, anchor, and screw must all work together.
- Choose your anchor first: Select an anchor that is rated to hold the weight of the item you’re hanging. The packaging will provide this information.
- Match the drill bit to the anchor: The anchor’s packaging will tell you exactly what size drill bit to use. For example, it might say “Use 1/4″ drill bit.” Using the wrong size bit will result in a hole that is too tight or too loose.
- Match the screw to the anchor: The packaging will also specify the right screw size to use with the anchor.
Getting this combination right ensures a strong, secure fit.
Step 4: Set Up Your Drill
Insert the correct masonry bit into your hammer drill and tighten the chuck securely. If your drill has different settings, do the following:
- Set it to the “hammer” mode. This is usually indicated by a small hammer icon.
- Select a low to medium speed. Starting with too much speed can cause the bit to wander or overheat.
Pro-Tip: Depth Gauge. How deep should you drill? Your hole needs to be slightly deeper than the length of your wall anchor. Measure your anchor, then measure that distance on your drill bit starting from the tip. Wrap a piece of colored tape around the bit at that point. When the tape touches the wall, you know you’ve drilled deep enough!
Step 5: Drill the Hole
Now for the main event. Hold the drill with both hands, perpendicular (at a 90-degree angle) to the wall. A firm grip is key for control.
Start drilling slowly to create a small indent. This will prevent the bit from slipping. Once the hole is started, you can increase the speed. Apply firm, steady pressure, but don’t force it. Let the hammer action of the drill do the work.
Periodically pull the drill bit out of the hole as you drill. This helps to clear out dust and debris, which allows the bit to work more effectively and stay cooler.
Step 6: Clean Out the Hole
Once you’ve drilled to the correct depth, it’s vital to clean out all the dust from the hole. If you leave the dust in, the anchor won’t be able to expand and grip the brick properly.
The best way to do this is with a shop vacuum. Place the nozzle over the hole to suck out all the loose material. You can also use a can of compressed air (wear your goggles!) or a small brush to clear it out.
Step 7: Insert the Wall Anchor
Take your plastic wall plug and push it into the clean hole. It should be a snug fit. If it’s too loose, your hole is too big. If it won’t go in, your hole might be too small or not clean enough.
Gently tap the anchor with a hammer until the end is flush with the surface of the brick. Don’t hit it too hard, or you could damage the anchor or the brick face.
Step 8: Drive the Screw
You’re at the finish line! Position the item you’re hanging over the hole, line it up with the anchor, and insert the screw. Use a screwdriver or your drill (on the regular ‘drive’ setting, not hammer) to drive the screw into the anchor.
As the screw goes in, it will expand the anchor, locking it firmly in place. Stop when the screw is snug. Over-tightening can strip the anchor or crack the brick.
Congratulations, you’ve successfully drilled into brick!
Important Safety Check: Check for Hidden Dangers
Before drilling into any wall, always consider what might be behind it. Use a stud finder with electrical and pipe detection capabilities to check for hidden wiring or plumbing. Drilling into a live wire or a water pipe can be extremely dangerous and costly to repair. This is especially important on interior brick walls.
Frequently Asked Questions (FAQ)
- 1. Can I drill into brick without a hammer drill?
- You can try, but it will be very difficult and slow. A regular drill lacks the hammering action needed to break up the brick efficiently. You will likely burn out your drill’s motor and dull your masonry bit. For your sanity and the life of your tools, a hammer drill is strongly recommended.
- 2. What’s the difference between a hammer drill and an impact driver?
- They sound similar but do different jobs. A hammer drill applies force straight forward (in and out) to pulverize masonry. An impact driver applies rotational force (like a series of tiny, powerful twists) to drive long screws into wood. You need a hammer drill for brick.
- 3. What kind of drill bit do I need for brick?
- You must use a masonry drill bit. These bits have a tungsten carbide tip that is hard enough to chip away at brick and concrete. Using a bit for wood or metal will destroy the bit and won’t make a dent in the brick.
- 4. How do I fill a hole in brick if I make a mistake?
- It’s an easy fix. You can buy brick-repair mortar or a color-matched exterior caulk/filler from any hardware store. Clean the hole, then press the filler material in. You can even try to match the texture of the surrounding brick before it dries.
- 5. Do I really need to use wall plugs in brick?
- Yes, 100%. A screw by itself has nothing to grip onto in a masonry hole. The hole is just a void. The wall plug (anchor) is what expands to create the friction and pressure needed for a secure hold. Never skip the anchor.
- 6. What happens if I accidentally drill into the mortar?
- If it’s for something very lightweight (like a small picture frame), you might be okay. However, for anything with significant weight, the mortar can crumble and fail over time. If you drilled in the wrong spot, it’s best to fill that hole and drill a new one in the center of a nearby brick.
- 7. How can I control all the dust?
- The best method is to have a friend hold the nozzle of a shop vacuum right below where you are drilling. This will catch most of the dust as it falls. Another trick is to tape a folded piece of paper or an open envelope to the wall just below your drill spot to act as a little dust-catching shelf.
You’ve Got This!
Drilling into brick might seem like a tough job, but as you’ve seen, it’s all about having the right tools and following a few simple steps. By choosing a hammer drill, a sharp masonry bit, and the correct anchors, you can tackle this project with confidence.
Remember to prioritize safety, measure carefully, and always drill into the solid brick. Now you’re ready to hang those shelves, mount that TV, or bring your outdoor decor dreams to life. Happy drilling!
