Yes, a cordless drill can go through brick, but with the right drill bit and technique, it’s quite manageable. You’ll need a masonry drill bit and to set your drill to its hammer drill function for best results.
Ever looked at a brick wall and wondered if your trusty cordless drill could tackle it? It’s a common question, especially when you need to hang a shelf, mount a bracket, or start a small DIY project. While it might seem daunting, drilling into brick with a cordless drill is definitely achievable. You just need to know a few key things to make the job easier and avoid frustration. We’re here to guide you through it, step-by-step, with simple explanations and practical tips.
Can a Cordless Drill Go Through Brick? The Simple Answer
Yes, a cordless drill can go through brick, but you need the right tools and settings. Specifically, you’ll need a masonry drill bit and, ideally, a drill with a hammer function. Using a standard drill bit or a drill without the hammer setting will make the process much slower and more difficult, potentially damaging your drill.
Understanding Your Cordless Drill and Brick
Before we dive into the “how-to,” let’s quickly touch on why this question comes up so often and what makes drilling into brick different from drilling into wood or drywall.
Brick is a dense, hard material made from clay that’s been fired in a kiln. This makes it much tougher than softer materials like wood. Trying to drill into brick with a regular drill bit designed for wood or metal is like trying to cut through steel with a butter knife – it’s not going to work well, and you’ll likely end up with a dull bit and a lot of frustration.
Your cordless drill, while powerful, also has limitations. Not all cordless drills are created equal. Some are designed for lighter tasks, while others are built to handle tougher jobs. The key features to look for are power (measured in volts) and, crucially, a “hammer drill” function.
What is a Hammer Drill Function?
This is a game-changer for drilling into masonry. A hammer drill has a mechanism that, in addition to rotating the drill bit, also delivers rapid percussive blows – like a tiny jackhammer – to the back of the bit. This hammering action chips away at the hard material, making it much easier for the rotating bit to bore through.
If your cordless drill has a switch or setting that looks like a hammer icon, you’re in luck! This is the setting you’ll want to use for brick. If your drill doesn’t have this function, it’s still possible, but it will take significantly longer and require more effort.
Essential Tools You’ll Need
To successfully drill into brick with your cordless drill, gather these items:
Cordless Drill with Hammer Function: As mentioned, this is ideal. A drill with at least 18 volts will provide enough power for most brick-drilling tasks.
Masonry Drill Bits: These are specifically designed for drilling into hard materials like brick, concrete, and stone. They have a carbide tip, often with a chisel-like shape, that can withstand the abrasion. They are usually marked with a special symbol or simply labeled “Masonry.”
Safety Glasses: Essential for protecting your eyes from dust and debris.
Dust Mask: Brick dust can be harmful to inhale, so a mask is highly recommended.
Measuring Tape and Pencil: For marking your drilling location accurately.
Optional: Painter’s Tape: Applying a strip of painter’s tape over your mark can help prevent the drill bit from “walking” or slipping when you start drilling.
Optional: Vacuum Cleaner: To clean up the dust as you go.
Choosing the Right Masonry Drill Bit
Masonry drill bits come in various sizes, measured by their diameter. You’ll need to choose a size appropriate for the screw, anchor, or fastener you plan to use. Always check the recommended drill bit size for your specific hardware.
Key Features of Masonry Drill Bits:
Carbide Tip: This is the hardened metal tip that does the cutting. It’s usually a darker color and has a distinct shape.
Flutes: The spiral grooves that help clear dust away from the hole. Masonry bits have deeper, wider flutes for this purpose.
You can find masonry drill bits at any hardware store or home improvement center. They are relatively inexpensive and a worthwhile investment if you plan on doing any work involving masonry. For more information on drill bits, you can check out this guide from The Spruce.
Step-by-Step Guide: Drilling Through Brick with a Cordless Drill
Now, let’s get to the action. Follow these steps for a smooth drilling experience:
Step 1: Prepare Your Workspace and Safety Gear
First things first: safety!
1. Put on your safety glasses. This is non-negotiable. Brick dust and small fragments can fly out unexpectedly.
2. Wear your dust mask. Protect your lungs from fine particles.
3. Clear the area. Make sure there are no obstructions around where you’ll be drilling.
4. If drilling indoors, consider laying down a drop cloth or using a vacuum cleaner attachment to catch dust.
Step 2: Mark Your Drilling Spot
Use your measuring tape and pencil to mark the exact spot where you want to drill.
For precision: You can place a piece of painter’s tape over the mark. This provides a better grip for the drill bit when you start and helps prevent the bit from wandering.
Step 3: Select and Insert the Masonry Drill Bit
1. Choose the correct size masonry drill bit for your needs.
2. Open the chuck of your cordless drill by twisting the collar.
3. Insert the shank (the smooth end) of the drill bit into the chuck.
4. Tighten the chuck firmly by hand or using a chuck key if your drill has one. Ensure the bit is held securely and doesn’t wobble.
Step 4: Set Your Drill Settings
This is where you prepare your drill for the task:
1. Engage the Hammer Drill Function: Locate the switch or dial on your drill that controls the drilling mode. Select the hammer drill setting (often indicated by a hammer icon).
2. Set the Speed: For drilling into brick, it’s best to start with a lower speed setting. This gives you more control and prevents the bit from overheating or “chattering” against the brick. Most drills have a speed selector, often a button or a sliding switch.
3. Check the Direction: Ensure your drill is set to rotate clockwise (forward) for drilling. There’s usually a lever or switch to control the forward/reverse direction.
Step 5: Start Drilling
Now for the actual drilling:
1. Position the Drill Bit: Place the tip of the masonry drill bit directly on your marked spot. Hold the drill perpendicular (straight up and down) to the brick surface.
2. Apply Gentle Pressure: Start by applying light, steady pressure. Let the hammer action do the work.
3. Begin Drilling Slowly: Squeeze the trigger gently to start the drill at a low speed.
4. Increase Pressure and Speed Gradually: As the bit starts to bite into the brick, you can gradually increase the pressure and speed.
5. Drill in Short Bursts: It’s a good practice to drill for about 10-15 seconds at a time, then pull the drill bit out slightly (while still spinning) to clear dust from the hole. This also helps to cool the bit.
6. Maintain Perpendicularity: Keep the drill as straight as possible throughout the process. Angling the drill can cause the bit to bind or break.
Step 6: Clearing Dust and Debris
As you drill, dust will accumulate in the hole. Periodically:
1. Withdraw the Drill Bit: Pull the spinning drill bit out of the hole to clear the dust.
2. Blow out the Hole: You can use compressed air, or even your mouth (with a mask on!), to blow the dust out of the hole. A small vacuum cleaner hose can also be effective.
3. Repeat: Continue drilling in short bursts, clearing dust as needed, until you reach your desired depth.
Step 7: Reaching the Desired Depth
Depth Stop: Many cordless drills have an adjustable depth stop rod that attaches to the back of the drill. This helps you drill to a specific depth without overshooting. If yours has one, set it to the required depth before you start.
Marking the Bit: If you don’t have a depth stop, you can wrap a piece of painter’s tape around the drill bit at the desired depth. Stop drilling when the tape reaches the surface of the brick.
Step 8: Finishing Up
Once you’ve reached the required depth:
1. Keep the drill spinning as you slowly withdraw it from the hole. This helps to clean out any remaining debris.
2. Clean the hole: Use your vacuum or compressed air to ensure the hole is clean and free of dust. This is crucial for anchors to grip properly.
3. Insert your anchor or fastener.
What If My Drill Doesn’t Have a Hammer Function?
Don’t despair if your cordless drill lacks a hammer function. You can still drill into brick, but it will require more patience and effort.
Use a Sharp Masonry Bit: Ensure your masonry bit is new and sharp. A dull bit will make the task nearly impossible.
Apply Steady, Firm Pressure: You’ll need to apply more consistent downward pressure.
Drill Slower: Start at a very slow speed and gradually increase it. Avoid high speeds, as this can cause the bit to overheat.
Clear Dust Frequently: Because there’s no hammer action to help eject dust, you’ll need to withdraw the bit more often to clear the hole.
Consider a Corded Hammer Drill: For frequent or larger projects, investing in a corded hammer drill might be a better long-term solution. They typically offer more power and sustained hammering action.
Common Problems and How to Solve Them
Even with the right tools, you might encounter a few hiccups. Here’s how to troubleshoot:
Drill Bit Not Biting:
Problem: The bit is spinning but not making progress.
Solution: Ensure you are using a masonry drill bit. Check that you have the hammer function engaged and are applying enough steady pressure. Make sure your drill bit is sharp.
Drill Bit “Walking”:
Problem: The bit is slipping on the surface of the brick when you start.
Solution: Use painter’s tape over your mark. Start drilling very slowly and apply a little more pressure initially to create a small indentation for the bit to grip.
Overheating Drill Bit:
Problem: The drill bit feels excessively hot.
Solution: You’re likely drilling too fast or for too long without clearing dust. Reduce your speed, drill in shorter bursts, and withdraw the bit more frequently to clear dust and allow it to cool.
Drill Overheating:
Problem: Your drill itself is getting very hot.
Solution: This could be due to the drill not being powerful enough for the task, or you’re pushing it too hard. Take breaks to let the drill cool down. If it continues, your drill might not be suited for drilling brick, or you may need a more powerful model.
Hitting Mortar vs. Brick:
Problem: You might encounter softer mortar joints between bricks.
Solution: The drill bit will go through mortar much easier than brick. Simply continue drilling. If you need to drill into a specific spot, try to aim for the brick itself.
When to Consider a More Powerful Tool
While a cordless drill can handle many brick-drilling tasks, there are situations where you might need something more robust:
Very Hard Bricks: Some older bricks or specialized types can be exceptionally hard.
Large Holes: If you need to drill holes larger than 1/2 inch (12-13mm), especially for things like large anchors or conduit, a standard cordless drill might struggle.
Frequent Drilling: If you’re undertaking a major renovation or construction project that involves a lot of drilling into brick, a corded hammer drill or even a rotary hammer will be more efficient and durable.
Concrete: While this guide focuses on brick, if you need to drill into concrete, a hammer drill or rotary hammer is almost always necessary for efficient work.
