Understanding Brick and Drilling

Brick, in its simplest form, is a building material made from clay or shale, fired in a kiln. This firing process makes it hard and durable, but also somewhat brittle. Understanding this is key to drilling effectively. You’re not trying to blast through it, but rather grind away the material in a controlled manner. When you’re asking yourself “can a drill go through brick,” it’s important to know that not all drills are created equal for this task. Standard drills might struggle or overheat, leading to frustration and potentially damaged tools. For brick, you typically need a drill with either a hammer function or a specialized masonry drill bit, or ideally both.

The type of brick also plays a role. Older, softer bricks might be easier to drill than modern, harder, and denser bricks. However, the principles remain the same. The key is to use the correct tool, the correct bit, and the correct technique. This ensures you achieve a clean hole without excessive dust, chipping, or damaging your drill. We’ll cover the essential tools and steps to make sure you get the job done right the first time.

What You’ll Need: The Right Tools for the Job

Before you start drilling into brick, gathering the right equipment is crucial. This will not only make the job easier but also safer and more effective. Think of it like preparing for any important task – the better your setup, the better the outcome.

Essential Drill Types

When considering “can a drill go through brick,” the type of drill you use is paramount. Not all drills are designed for masonry work.

• Hammer Drill: This is your best friend for drilling into brick. A hammer drill combines rotation with a percussive hammering action, which helps to break up the masonry material as it drills. This significantly speeds up the process and reduces the effort required. Most modern hammer drills have a setting for drilling with or without the hammer function, making them versatile for wood, metal, and masonry.
• Rotary Hammer: For much larger or more frequent masonry drilling tasks, a rotary hammer is even more powerful than a standard hammer drill. They use a piston mechanism to deliver a much stronger hammering blow. While overkill for hanging a picture, they are excellent for demolition or drilling large anchor holes.
• Standard Drill/Driver: While technically possible to drill into softer brick with a standard drill and a masonry bit, it’s not recommended for anything more than very light-duty tasks. Standard drills lack the percussive action needed to efficiently break down brick, leading to slow progress, overheating, and potential damage to the drill or the wall.

Crucial Drill Bits

The drill bit is just as important as the drill itself. Using the wrong bit will make the job impossible and can damage your bit and drill.

• Masonry Drill Bits: These bits are specifically designed for drilling into hard materials like brick, concrete, and stone. They typically have a carbide tip, which is much harder than standard steel bits. The tip is often shaped like a chisel or spade, designed to chip away at the material.
• Carbide-Tipped Masonry Bits: Within masonry bits, look for those with a reinforced carbide tip. These are the most durable and efficient for brick. They come in various sizes, and you’ll need to choose the size appropriate for the anchor or screw you intend to use.

Safety Gear – Non-Negotiable!

Drilling into brick creates dust, and safety should always be your top priority.

• Safety Glasses: Essential to protect your eyes from flying debris and dust.
• Dust Mask: Brick dust can be harmful if inhaled, so a good quality dust mask (like an N95 respirator) is highly recommended.
• Ear Protection: Hammer drills can be loud, so earplugs or earmuffs are a good idea, especially for extended drilling.
• Gloves: Protect your hands and improve grip.

Other Helpful Tools

• Measuring Tape: For accurate placement of your holes.
• Pencil or Marker: To mark where you want to drill.
• Level: To ensure your holes are straight if you’re drilling multiple points for something like a shelf.
• Vacuum Cleaner: To clean up dust as you go, or at least immediately after. A shop vac with a dust collection attachment is ideal.
• Painter’s Tape: Placing a piece of tape over your mark can help prevent the drill bit from “walking” or slipping on the surface.
• Drill Depth Stop: If you need to drill to a specific depth, a depth stop attachment (often comes with drills) or a piece of tape on the drill bit can be very useful.

Step-by-Step Guide: Drilling Through Brick

Now that you have your tools, let’s get down to the actual process. Following these steps will help you drill safely and effectively.

Step 1: Planning and Marking

Before you even pick up the drill, decide exactly where you want to drill. Measure twice, drill once!

• Use your measuring tape and pencil to mark the precise spot for your hole.
• If you’re drilling multiple holes (e.g., for a bracket or shelf), use a level to ensure they are aligned correctly.
• Consider the type of fixings you’ll be using (anchors, screws) as this will dictate the size of the hole you need to drill. You can find recommended drill bit sizes on the packaging of your wall anchors.

Step 2: Prepare the Drill and Bit

This is where you set up your drill for success.

• Insert the Masonry Bit: Open the chuck of your drill (the part that holds the bit) by twisting it. Insert the shank of your masonry drill bit firmly, then twist the chuck closed tightly to secure the bit. Ensure it’s centered and doesn’t wobble.
• Set the Drill Mode: If you’re using a hammer drill, switch it to the hammer drill setting (often indicated by a hammer icon). If you’re drilling into mortar lines or very soft brick, you might consider using the standard drilling setting without the hammer action.
• Set the Depth Stop (Optional but Recommended): If you need a specific depth, attach the depth stop to your drill barrel or wrap a piece of painter’s tape around the drill bit at the desired depth. Make sure the tape aligns with the chuck when the bit is at the correct depth.

Step 3: Starting the Hole

This initial step is crucial for accuracy.

• Apply Painter’s Tape: Place a small piece of painter’s tape over your marked spot. This helps prevent the drill bit from “skittering” or wandering across the surface when you start.
• Position the Drill: Hold the drill perpendicular to the brick surface. Place the tip of the masonry bit directly on your mark.
• Start Slowly: Begin drilling at a slow speed with light pressure. This allows the bit to bite into the brick and create a small indentation, guiding the bit.

Step 4: Drilling the Hole

Now, you’ll apply more consistent pressure and speed.

• Increase Speed and Pressure: Once the bit has started to bite, increase the drill speed to a medium to high setting. Apply steady, consistent pressure. Let the drill do the work; don’t force it excessively.
• Engage Hammer Action: With a hammer drill, keep the hammer function engaged. The pounding action helps break up the brick material.
• Clear Debris: Periodically pull the drill bit back slightly while it’s still spinning. This helps to clear dust and debris from the hole, preventing the bit from binding and allowing for more efficient drilling. You might hear the term “back-reaming” for this.
• Maintain Control: Keep the drill as straight as possible. If you feel the drill starting to twist in your hands, ease up on the pressure or switch to a lower speed.

Step 5: Finishing and Cleaning

Once you reach the desired depth, it’s time to finish up.

• Reach Depth: Continue drilling until you reach your desired depth (indicated by your depth stop or tape mark).
• Withdraw the Bit: While the drill is still spinning slowly, gently pull the bit straight out of the hole.
• Clean the Hole: Use a vacuum cleaner or a brush to remove all dust from the hole. A clean hole is essential for proper anchor insertion. You can also use a can of compressed air to blow out any remaining dust.
• Insert Anchor: If using wall anchors, insert them into the clean hole. They should fit snugly. If an anchor is too loose, you might need to drill a slightly smaller hole or use a different type of anchor.

Troubleshooting Common Issues

Even with the best preparation, you might encounter a few snags. Here’s how to handle them:

The Drill Bit is Not Cutting

• Check Drill Mode: Ensure your hammer drill is on the hammer setting.
• Check Bit Condition: Is the carbide tip worn down or damaged? A dull bit won’t cut effectively.
• Apply More Pressure: Ensure you’re applying steady, firm pressure.
• Try a Different Spot: Sometimes you might hit a particularly hard aggregate in the brick. Shifting slightly might help.

The Brick is Chipping Excessively

• Ease Up Pressure: Too much force can cause chipping, especially on softer or older bricks.
• Start Slower: Make sure you’re starting the hole with slow speed to create a clean entry point.
• Use Painter’s Tape: Ensure you’ve applied painter’s tape over the mark to help guide the bit.
• Consider Mortar Lines: If possible, drilling into the mortar between bricks can be easier and produce less chipping than drilling directly into the brick itself.

The Drill Bit is Stuck

• Don’t Force It: If the bit gets stuck, don’t just keep trying to power through.
• Reverse the Drill: Switch your drill to the reverse setting and try to back the bit out slowly.
• Clear Debris: If it’s stuck due to dust buildup, try pulling it out slightly, then re-inserting it and drilling forward again to clear the dust.

When to Call a Professional

While drilling brick is a manageable DIY task, there are situations where it’s better to call in the pros:

• Structural Load-Bearing Walls: If you’re unsure about the wall’s integrity or if it’s load-bearing, consult a structural engineer or experienced contractor. Drilling in the wrong spot could compromise structural safety.
• Very Large Holes: For holes larger than 1/2 inch, especially if you need many of them, a rotary hammer or professional services might be more efficient.
• Lack of Confidence: If you’re uncomfortable or unsure about any step, it’s always safer to hire a professional.
• Delicate Masonry: Historic buildings or decorative brickwork might require specialized techniques to avoid damage.

Understanding Brick Types and Drilling

The type of brick you’re drilling into can influence the process. While this guide focuses on general brick drilling, knowing the difference can be helpful.

Drilling into Mortar vs. Brick

A common question is whether to drill into the brick itself or the mortar lines. There are pros and cons to both:

• Drilling into Mortar:
  • Pros: Mortar is generally softer than brick, making it easier and faster to drill. It also tends to produce less dust and chipping.
  • Cons: Mortar joints might not be strong enough for certain types of anchors or heavy loads. The hole might be too large if the mortar has eroded.
• Drilling into Brick:
  • Pros: Brick is typically stronger and provides a more secure base for anchors, especially for heavier items.
  • Cons: It’s harder work, requires more powerful tools, and can create more dust and chipping.

Recommendation: For most common DIY tasks like hanging shelves or pictures, if the brick is hard, aim for the mortar line. If you’re mounting something that requires a very strong hold, or if the mortar is crumbling, drill into the brick. Always ensure your chosen anchor is suitable for the material you’re drilling into.

Frequently Asked Questions

Can I use a regular drill to drill through brick?

While it’s technically possible to drill into very soft brick or mortar with a standard drill and a good quality masonry bit, it’s not recommended for efficient or effective results. Standard drills lack the percussive action of a hammer drill, which is crucial for breaking down the hard material. You’ll likely experience slow progress, overheating of the drill, and potential damage to the tool. For best results, a hammer drill and a carbide-tipped masonry bit are essential.

What size drill bit do I need for brick?

The size of your drill bit depends entirely on the type of anchor or screw you plan to use. Wall anchor packaging will specify the recommended drill bit diameter for installation. Common sizes for wall anchors used in brick range from 5mm (3/16 inch) to 10mm (3/8 inch) or larger for substantial fixings.

How deep should I drill into brick?

You should drill to the depth recommended for your wall anchor or screw. This information is usually found on the anchor’s packaging. If using a depth stop or tape on your drill bit, ensure it’s set to the correct depth, plus a little extra to allow for dust accumulation at the bottom of the hole.

What is the best way to avoid dust when drilling brick?

Drilling brick inevitably creates dust. To minimize it, you can:

• Use a vacuum cleaner with a hose attachment held close to the drill bit as you work.
• Drill slowly and periodically pull the bit out to clear dust from the hole.
• Consider drilling into the mortar lines rather than the brick itself, as mortar is
