Yes, a cordless drill can go through brick with the right technique and a masonry drill bit. You’ll need to use a hammer drill setting and a slow, steady pressure for best results.
Have you ever looked at a brick wall and wondered if your trusty cordless drill could handle it? It’s a common question, especially when you need to hang a shelf, mount a bracket, or start a DIY project that involves drilling into masonry. The good news is, with the right tools and approach, your cordless drill can absolutely tackle brick. It might not be as straightforward as drilling into wood, but with a few key adjustments, you’ll be drilling holes in brick like a pro. Let’s walk through each step with real examples to make it super easy.
Understanding Brick and Drilling
Brick is a dense material made from clay, fired in a kiln. Unlike wood or drywall, it’s hard and abrasive. This means you need specific tools and techniques to drill into it effectively without damaging your drill or making a mess.
Why is drilling into brick different?
Hardness: Brick is much harder than most common building materials.
Abrasiveness: The surface can wear down standard drill bits quickly.
Dust: Drilling creates fine dust that needs to be managed.
Material Integrity: You want to drill a clean hole without cracking the brick.
What You’ll Need: The Right Tools
Before you start, gather these essential items. Having the correct equipment makes all the difference.
Cordless Drill with Hammer Function: This is crucial. A standard drill won’t have enough power or the right action. Look for a drill that specifies “hammer drill” or “hammer action.” Many modern cordless drills offer this feature.
Why a Hammer Drill? The hammer function adds a percussive, pounding action to the rotation. This pounding helps to break up the brick material as the bit turns, making it much easier to penetrate. Think of it like a tiny jackhammer.
Masonry Drill Bits: These are specially designed for drilling into hard materials like brick, concrete, and stone.
What to look for: They typically have a carbide tip, which is extremely hard and can withstand the friction and impact. They are usually marked with symbols indicating their suitability for masonry.
Sizes: Have a variety of sizes ready, depending on the size of the screw or anchor you plan to use. Common sizes for DIY projects are 5mm, 6mm, 8mm, and 10mm.
Where to find them: You can find these at any hardware store or home improvement center. Brands like Bosch, DeWalt, and Milwaukee offer excellent masonry drill bits.
Safety Glasses: Absolutely non-negotiable. Brick dust and fragments can fly out at high speed. Protect your eyes!
Dust Mask: Brick dust is fine and can be harmful if inhaled. A simple disposable dust mask will do.
Measuring Tape and Pencil: For marking exactly where you want to drill.
Painter’s Tape (Optional but Recommended): Applying a piece of painter’s tape over your mark can help prevent the drill bit from “walking” or slipping when you start.
Vacuum Cleaner or Dust Blower (Optional): To clear out dust from the hole as you go.
Gloves (Optional): For a better grip and to protect your hands.
Step-by-Step Guide: Drilling Through Brick
Now that you have your tools, let’s get drilling! Follow these steps carefully.
Step 1: Mark Your Spot
Decide precisely where you need the hole.
Use a measuring tape to ensure accuracy.
Mark the spot with a pencil.
Pro Tip: For extra stability and to prevent the drill bit from wandering, place a small piece of painter’s tape over your pencil mark. Then, re-mark the center of your hole on the tape.
Step 2: Select the Right Drill Bit and Set Your Drill
Choose a masonry drill bit that matches the size of the screw or anchor you intend to use. If you’re unsure, it’s often better to start with a slightly smaller bit and enlarge the hole if necessary.
Insert the drill bit firmly into the chuck of your cordless drill. Ensure it’s tightened securely.
Crucially, switch your drill to “Hammer Drill” mode. This is usually indicated by a hammer icon on the drill’s settings. If your drill doesn’t have this, it will be much harder, and potentially impossible, to drill through brick effectively.
Set your drill to a low to medium speed setting. High speeds can overheat the bit and drill, and reduce control.
Step 3: Start Drilling with Gentle Pressure
Hold the drill firmly with both hands.
Position the tip of the drill bit directly on your marked spot.
Begin drilling at a slow speed.
Apply light, steady pressure. Let the hammer action do the work. Don’t force it.
Think of it as a controlled push, not a brute force shove.
Step 4: Maintain Consistent Pressure and Clear Dust
As the bit starts to bite into the brick, you can gradually increase the pressure slightly, but always maintain a steady, consistent force.
Periodically pull the drill bit out of the hole while it’s still spinning slowly. This helps to clear out the brick dust and debris, preventing the hole from becoming clogged and allowing the bit to cut more efficiently.
You can use a vacuum cleaner hose or a blast of compressed air to clean out the hole.
Step 5: Continue Drilling Until You Reach Desired Depth
Keep drilling, applying steady pressure and clearing dust as needed.
If you are drilling a deep hole, you might feel the drill bit start to heat up. It’s okay to pause for a few seconds to let it cool, especially if you’re working with a less powerful drill.
The hammer action will create a characteristic “grinding” sound. This is normal.
Step 6: Finishing the Hole
Once you’ve reached the desired depth, slowly withdraw the drill bit while it’s still spinning.
Clean out any remaining dust from the hole.
You can now insert your wall anchor or screw.
Common Challenges and How to Solve Them
Even with the right tools, you might encounter a few issues. Here’s how to handle them.
Drill Bit Not Cutting:
Problem: The bit is just spinning and not making progress.
Solution: Ensure you are in hammer drill mode. Check if your drill bit is a masonry bit; a standard wood or metal bit will not work. Make sure the bit isn’t worn out; carbide tips can dull over time.
Drill Bit Getting Stuck:
Problem: The bit gets lodged in the hole.
Solution: If you feel it getting stuck, stop drilling immediately. Try reversing the drill (if your drill has a reverse function) while applying gentle pressure. If that doesn’t work, you may need to carefully wiggle the drill bit or try to clear debris from around it.
Overheating:
Problem: The drill or the bit feels excessively hot.
Solution: This usually means you’re drilling too fast or applying too much pressure. Slow down, reduce pressure, and allow the drill and bit to cool periodically. Clearing dust from the hole also helps with cooling.
Cracking the Brick:
Problem: The brick starts to crack around the hole.
Solution: This often happens if you’re using too much force, drilling too fast, or using a bit that’s too large for the brick. Use a slower speed, lighter pressure, and ensure you’re clearing debris. If a crack starts, stop and assess if you can continue or if you need to reposition the hole.
When a Cordless Drill Might Not Be Enough
While most modern cordless drills with hammer functions can handle brick, there are situations where they might struggle or be impractical.
Very Hard or Dense Brick: Some types of brick, especially older, very dense, or vitrified bricks, can be exceptionally hard to drill.
Extensive Drilling: If you have many holes to drill, or need to drill very deep holes, a powerful corded hammer drill or a dedicated rotary hammer might be more efficient and less prone to overheating.
Lack of Hammer Function: If your cordless drill does not have a hammer function, it will be extremely difficult, if not impossible, to drill through brick. You’d essentially be trying to grind through it, which is inefficient and will likely damage your drill.
Alternatives and When to Call a Professional
If you find that your cordless drill is struggling, or if you’re working with very hard materials or need to drill into structural elements, consider these options:
Corded Hammer Drill: These often offer more power and sustained performance than cordless models.
Rotary Hammer: For heavy-duty tasks, like drilling large holes or working with concrete, a rotary hammer is the professional choice. They deliver much more impact force.
Professional Help: For significant projects, especially if you’re unsure about the structural integrity of the wall, it’s always best to consult a professional contractor or handyman.
Maintaining Your Drill and Bits
Proper care ensures your tools last longer and perform better.
Clean Your Drill: After drilling into brick, dust will get into your drill. Use compressed air or a soft brush to clean out the vents and chuck.
Store Bits Properly: Keep your masonry bits in their case to protect the carbide tips.
* Check Your Drill’s Battery: Ensure your battery is fully charged before starting a drilling project. Drilling into brick consumes more power than drilling into softer materials.
