Yes, cordless drills are often powerful enough for masonry, especially newer models with advanced battery technology and robust motor designs. For tougher jobs, look for high-torque brushless motors and lithium-ion batteries.
Have you ever wondered if a cordless drill can really tackle tough materials like brick or concrete? It’s a common question, and for good reason! Many people associate power with those big, corded tools they might have seen or used in the past. But the technology in cordless drills has come a long way. You might be surprised to learn just how capable these battery-powered workhorses have become. If you’re looking for a straightforward, practical answer to whether cordless drills are powerful enough, especially for masonry, you’ve come to the right place. Let’s explore what makes them tick and how to choose the right one for your needs.
Understanding Cordless Drill Power: What Does It Mean?
When we talk about drill power, we’re really talking about its ability to spin a bit through a material, especially a tough one like masonry. Several factors contribute to this.
Voltage (V): Think of voltage as the “oomph” behind the drill. Higher voltage generally means more power. Most cordless drills for DIY use are 12V or 18V, while professional-grade models can go up to 36V or even higher. For masonry, an 18V drill is usually the minimum you’ll want.
Amperage-Hour (Ah): This rating tells you how long the battery can deliver its power. A higher Ah rating means longer runtime, not necessarily more power, but it’s crucial for sustained work.
Motor Type: This is a big one!
Brushed Motors: These are the traditional type. They work well but can overheat with heavy use and are less efficient.
Brushless Motors: These are the modern marvels. They use electronic controls instead of physical brushes, making them more efficient, cooler running, and significantly more powerful and durable. If you’re serious about drilling into masonry, a brushless motor is highly recommended.
Torque (Nm or in-lbs): Torque is the rotational force. It’s what directly drives the drill bit through the material. Higher torque is essential for drilling into hard substances. Cordless drills often have adjustable torque settings (clutches) to prevent overtightening screws, but the maximum torque is what matters for drilling.
Cordless Drills and Masonry: A Closer Look
So, can a cordless drill handle masonry? The answer is a qualified yes.
For light-duty tasks like drilling small holes in mortar between bricks or for hanging a lightweight picture frame on a plaster wall, most 18V cordless drills will do the job just fine. However, if you need to drill into solid concrete, dense brick, or frequently work with masonry, you need to be more discerning.
Key Considerations for Masonry:
1. Drill Type: Not all cordless drills are created equal for masonry. You need a drill with a dedicated hammer drill function.
Standard Cordless Drill: These drills only rotate the bit. They are suitable for wood, metal, and soft materials but will struggle immensely with masonry.
Hammer Drill (Cordless): These drills combine rotation with a rapid hammering action. This percussive force is what breaks up the hard material, making drilling into concrete and brick much easier and faster. This is the type you need for masonry.
Impact Driver: While powerful for driving screws, impact drivers have a different kind of hammering action (applied along the axis of the bit) that’s not ideal for drilling holes in masonry. They can be useful for driving masonry screws after you’ve pre-drilled, but they aren’t the primary tool for drilling the hole itself.
2. Power and Torque: As mentioned, look for 18V or higher voltage drills. Brushless motors are a significant advantage. Check the drill’s specifications for its maximum torque. For masonry, you’ll want a drill with a good amount of torque, often specified as over 500 in-lbs (or around 60 Nm).
3. Battery Technology: Lithium-ion (Li-ion) batteries are standard now and offer excellent power and longevity compared to older NiCad batteries. Ensure the drill you choose uses Li-ion batteries.
4. Drill Bits: Even the most powerful drill will be useless without the right drill bits. For masonry, you must use masonry drill bits. These have a hardened carbide tip designed to chip away at concrete and brick. Always start with a smaller bit and work your way up if needed.
When a Cordless Drill Might NOT Be Enough for Masonry
While modern cordless drills are very capable, there are scenarios where they might fall short, especially if you’re using a less powerful model or tackling very demanding tasks:
Very Hard Materials: Drilling into dense granite, very hard concrete mixes, or large sections of thick brick can still be challenging for even a good 18V cordless hammer drill, especially if you need to drill many deep holes.
Extended Heavy Use: If you’re doing extensive demolition or drilling dozens of deep holes in a single session, a corded hammer drill or a dedicated SDS rotary hammer might offer more sustained power and less risk of overheating the battery or motor.
Lack of Hammer Function: A standard cordless drill (without the hammer setting) will simply not be effective for drilling into masonry.
Best Cordless Drills for Masonry: What to Look For
When shopping for a cordless drill that can handle masonry, keep these features at the forefront:
Hammer Drill Functionality: Absolutely essential. Look for a button or switch that engages the hammer action.
Brushless Motor: For maximum power, efficiency, and tool lifespan.
18V or Higher Voltage: Provides the necessary power.
High Torque Output: Check the specifications. More is generally better for masonry.
Variable Speed Trigger: Allows for precise control, starting slowly to position the bit accurately before ramping up speed.
Adjustable Clutch: While primarily for screws, it helps prevent stripping screw heads or damaging softer materials when not in hammer mode.
Comfortable Ergonomics: You’ll be holding the drill for a while, so comfort and balance are important.
Battery System: If you already own tools from a particular brand, sticking with that brand’s battery system can save you money.

How to Drill Masonry with a Cordless Drill
Using a cordless hammer drill for masonry is straightforward, but a few tips will make the job easier and safer.
What You’ll Need:
Cordless Hammer Drill (18V or higher, brushless recommended)
Masonry Drill Bits (carbide-tipped) of the desired size
Safety Glasses (essential!)
Ear Protection (optional but recommended for prolonged use)
Dust Mask (important for concrete dust)
Measuring Tape and Pencil
A damp cloth or spray bottle (to cool the bit occasionally)
Optional: A depth gauge or masking tape on the bit to mark drilling depth
Steps:
1. Select the Right Drill Bit: Choose a carbide-tipped masonry bit that matches the diameter of the hole you need. If you’re using a wall anchor, the anchor packaging will specify the required bit size.
2. Set Your Drill:
Insert the masonry bit firmly into the drill chuck. Ensure it’s tightened securely.
Switch the drill to hammer drill mode. This is crucial! If your drill has a speed setting, choose a medium speed for general masonry.
If drilling into softer materials like brick or mortar, you might be able to use a lower torque setting or even turn off the hammer function for initial hole placement, then switch to hammer mode. For solid concrete, always start in hammer mode.
3. Mark Your Hole: Use your pencil to mark the exact spot where you want to drill.
4. Position the Drill:
Place the tip of the drill bit precisely on your mark.
Hold the drill firmly with both hands, keeping it perpendicular to the surface. If your drill has an auxiliary handle, attach and use it for better control and stability.
Ensure you are wearing your safety glasses.
5. Start Drilling:
Begin drilling at a slow speed to create a small indentation, preventing the bit from wandering.
Once the bit is seated, increase the speed.
Apply steady, firm pressure. Let the hammer action of the drill do the work; don’t force it excessively. Pushing too hard can overheat the motor or break the bit.
Periodically pull the drill bit out of the hole while it’s still spinning slowly. This helps clear out dust and debris, which allows the bit to cut more effectively and prevents overheating. You can also use compressed air or a vacuum to clear the hole.
6. Monitor and Cool:
If you’re drilling deep holes or working with very hard materials, the bit can get very hot. You might need to pause every minute or so to let the bit cool down. Dipping the hot bit into water can cool it quickly, but be aware this can sometimes shorten the bit’s lifespan if done excessively. A damp cloth works too.
Keep an eye on your drill’s motor. If it feels excessively hot, take a break.
7. Reach Depth: If you need to drill to a specific depth (e.g., for a wall anchor), use a depth gauge or wrap a piece of masking tape around the drill bit a few inches from the tip to indicate when you’ve reached the desired depth.
8. Finish the Hole: Once you’ve reached the required depth, continue drilling for a few more seconds to ensure the hole is clear of debris. Then, slowly withdraw the drill bit while it’s still spinning.
9. Clean Up: Clear any remaining dust from the hole using compressed air or a vacuum cleaner before inserting your anchor or screw.
Alternatives for Very Demanding Masonry Work
While cordless hammer drills are great, for extremely tough or high-volume masonry tasks, you might consider:
Corded Hammer Drills: Offer consistent power without battery limitations, but you’re tethered by a cord.
Rotary Hammers (SDS): These are the heavy-duty champions for masonry. They have a more powerful hammering mechanism (pneumatic or electro-pneumatic) and use special SDS bits that lock into the tool. They are designed for drilling larger holes, breaking concrete, and chiseling. If you’re regularly drilling into concrete, a rotary hammer is a worthwhile investment. You can find both corded and cordless SDS rotary hammers.
Frequently Asked Questions About Cordless Drills and Masonry
Q1: Can I use my regular cordless drill to drill into brick?
A1: Only if it has a dedicated “hammer drill” setting. A standard cordless drill that only rotates will struggle immensely and is not designed for masonry.
Q2: What’s the difference between a hammer drill and an impact driver for masonry?
A2: A hammer drill’s hammering action is applied along the axis of the drill bit as it rotates, breaking up material. An impact driver’s hammering action (called “percussive rotation”) is applied perpendicular to the output shaft and is primarily designed for driving screws with high torque. For drilling holes in masonry, a hammer drill is the correct tool.
Q3: Do I need special drill bits for concrete?
A3: Yes, absolutely. You need masonry drill bits, which have a hardened carbide tip designed to withstand the abrasive nature of concrete and brick. Regular drill bits will be quickly destroyed.
Q4: How deep can a cordless drill realistically drill into concrete?
A4: For most 18V cordless hammer drills, drilling holes up to 3-4 inches deep for common anchors is generally achievable. For deeper or wider holes, you might need a more powerful tool or a rotary hammer.
Q5: My cordless drill is struggling with masonry. What could be wrong?
A5: Several things could be happening:
You might be using a standard drill without a hammer function.
The drill bit might be dull or not a masonry bit.
You might not be applying enough steady pressure.
The drill itself might be underpowered for the task (e.g., a low-voltage drill, or one with a brushed motor).
The material you’re drilling into might be exceptionally hard.
You might need to clear debris from the hole more frequently.
Q6: How long will a battery last when drilling into masonry?
A6: This varies greatly depending on the drill’s power, the battery’s capacity (Ah), the material being drilled, and the depth of the hole. A good 18V brushless drill with a 4.0Ah or 5.0Ah battery can often drill dozens of common anchor holes on a single charge. For continuous, heavy-duty work, having a spare battery is always a good idea.
Q7: Is a cordless rotary hammer better than a cordless hammer drill for masonry?
A7: Yes, for demanding tasks. A cordless rotary hammer (often using SDS bits) provides significantly more power and efficiency for drilling into concrete and masonry due to its superior hammering mechanism. A cordless hammer drill is excellent for light to moderate masonry work, while a rotary hammer is for heavier-duty applications.
Conclusion: Your Cordless Drill Can Be a Masonry Master
The short answer is yes, your cordless drill can* be powerful enough for masonry, provided you have the right tool and the right technique. Look for an 18V (or higher) cordless hammer drill with a brushless motor, and always use masonry-specific drill bits. By understanding the features that contribute to a drill’s power and following best practices for drilling into hard materials, you can confidently tackle many DIY projects that involve brick and concrete. Don’t be afraid of the hammer function – it’s your secret weapon for conquering tough surfaces. Happy drilling!
