Understanding Your Drill: The Key Difference
The first thing to understand is that not all drills are created equal when it comes to tough materials like concrete. The magic word here is “hammer drill.”
Standard Drills vs. Hammer Drills
A standard drill, often called a drill/driver, is designed for softer materials like wood and metal. It spins the drill bit to create a hole. Simple enough, right?
A hammer drill, on the other hand, has an extra mechanism. When you engage the hammer function, it delivers rapid, short impacts (like a tiny hammer) along with the spinning motion. This percussive action is what breaks up the hard concrete, allowing the spinning bit to chip away at it effectively.
Why the Hammer Action Matters
Imagine trying to chip away at a rock with just a spinning stick. It wouldn’t do much. Now, imagine tapping that stick with a hammer while it spins – that’s essentially what a hammer drill does for concrete. The impacts are crucial for breaking down the dense material.
Will a Normal Drill Go Through Concrete? The Short Answer
As mentioned, a standard drill *without* a hammer function will find it extremely difficult, if not impossible, to drill through concrete. You might be able to make a very shallow indentation with a lot of effort and the right bit, but it won’t create a usable hole. You’ll likely overheat your drill, break your drill bits, and end up very frustrated.
So, if your drill is just a basic drill/driver, you’ll need to consider getting a hammer drill for concrete work.
What You Need: The Right Tools for the Job
To successfully drill into concrete, you’ll need a specific set of tools. Don’t skip these; they are essential for safety and effectiveness.
Essential Tools Checklist:
- Hammer Drill: This is non-negotiable for concrete.
- Masonry Drill Bits: These are specially designed with a hardened tip (often carbide) to withstand the abrasive nature of concrete and the impact of a hammer drill.
- Safety Glasses: Concrete dust is harmful and flying debris is a real risk.
- Dust Mask: Protect your lungs from fine concrete particles.
- Work Gloves: For a better grip and protection.
- Measuring Tape and Pencil: To mark your drilling spots accurately.
- Vacuum Cleaner (Optional but Recommended): To clean up dust as you go.
Choosing the Right Masonry Bit
Drill bits come in various sizes and types. For concrete, you absolutely need masonry bits. They have a distinct, chisel-like tip made from carbide, which is much harder than steel. Standard wood or metal bits will dull and break almost immediately when used on concrete.
Masonry bits are also designed to work with the hammer function of a hammer drill. They have flutes (the spiral grooves) that are shaped to help clear out the dust and debris as you drill.
How to Drill into Concrete with a Hammer Drill: Step-by-Step
Now that you have your tools, let’s get drilling! Follow these steps carefully for a safe and successful experience.
Step 1: Prepare Your Workspace and Safety Gear
Before you even pick up the drill, ensure your area is safe. Clear away any clutter. Put on your safety glasses, dust mask, and gloves. If you’re drilling indoors, consider covering furniture or floors with a drop cloth, as concrete dust can spread easily.
Pro-Tip: If you’re drilling into a wall, check for electrical wires or plumbing pipes behind the surface. Use a stud finder or a pipe/wire detector if you’re unsure. Drilling into a live wire can be extremely dangerous!
Step 2: Mark Your Drilling Spot
Use your measuring tape and pencil to mark exactly where you want to drill your hole. Be precise, especially if you’re hanging something that needs to be level.
For pilot holes or starting points, you can lightly tap the tip of the masonry bit onto the mark with a hammer to create a small indentation. This helps prevent the bit from “walking” or slipping when you start drilling.
Step 3: Select and Insert the Masonry Bit
Choose the correct size masonry bit for your project. If you’re using anchors, the anchor packaging will usually specify the required drill bit diameter. Ensure the bit is securely inserted into the chuck of your hammer drill. Most modern hammer drills have keyless chucks, so you just twist the chuck to tighten it around the bit.
Safety Warning: Always ensure the drill is unplugged or the battery is removed before inserting or removing a drill bit.
Step 4: Set Your Hammer Drill Settings
Your hammer drill will likely have two settings: a standard drilling symbol (often a drill bit) and a hammer drilling symbol (often a hammer or a hammer with lines). Make sure the hammer drill function is selected.
You might also have a speed setting. For starting a hole in concrete, it’s often best to start at a lower speed to maintain control and prevent the bit from skipping. You can increase the speed as you get into the material.
Step 5: Start Drilling
Hold the hammer drill firmly with both hands. Place the tip of the masonry bit on your marked spot. Begin drilling at a slow speed, applying steady, firm pressure directly into the concrete. Let the hammer action do the work.
As you drill deeper, you may need to increase the speed slightly. Don’t force the drill; let the tool and bit do the cutting. If the drill starts to overheat or the bit seems to be struggling, pull the bit out slightly while it’s still spinning to clear out dust and debris from the hole. This also helps cool the bit.
Step 6: Clear Debris and Continue
Periodically, pull the drill bit out of the hole while it’s still spinning slowly. This helps to clear the hole of concrete dust and chips. You can use a vacuum cleaner with a crevice tool or a can of compressed air to remove the dust from the hole. Keeping the hole clear helps the bit cut more efficiently and prevents it from binding.
Continue drilling until you reach your desired depth. You can often tell you’ve reached the required depth by looking at the depth gauge on your drill or by measuring with a ruler.
Step 7: Finishing Up
Once you’ve drilled the hole to the correct depth, switch the drill to its regular drilling mode (no hammer action) and gently pull the bit out. This helps to smooth the edges of the hole.
Clean up the area thoroughly. Use your vacuum cleaner to collect any remaining dust. If you’re inserting an anchor, now is the time to gently tap it into the hole with a hammer until it’s flush with the surface.
When a Standard Drill Might Work (With Caveats)
There are very specific, limited scenarios where a standard drill *might* be able to make a tiny mark on concrete, but it’s not practical for creating a hole:
- Very Soft Concrete/Mortar: If you’re trying to drill into very old, crumbling mortar between bricks, or a particularly soft type of concrete, a standard drill with a good masonry bit might make some progress. However, it will still be slow and may damage the bit.
- Making a Small Indentation: If you only need a tiny mark to start a screw, and the concrete is very soft, you might achieve this.
In almost all cases where you need a proper hole (for anchors, screws, etc.), a standard drill is simply not the right tool for concrete.
Troubleshooting Common Issues
Even with the right tools, you might run into a few snags. Here’s how to deal with them:
- Drill Bit Not Cutting:
- Is it a masonry bit? If not, you need one.
- Is the hammer function engaged?
- Is the bit dull? Carbide-tipped bits can wear out over time.
- Are you applying enough pressure?
- Drill Overheating:
- Are you drilling too fast? Try a slower speed.
- Are you drilling continuously without clearing debris? Pull the bit out periodically.
- Is the bit binding in the hole? Ensure the hole is clear.
- Bit Walking:
- Did you create an indentation with a hammer first?
- Are you applying steady, direct pressure?
- Ensure the drill is perpendicular to the surface.
Alternatives to Hammer Drills for Concrete
If you don’t have a hammer drill and your project requires drilling into concrete, what are your options?
- Rotary Hammer: This is a more powerful tool than a hammer drill. It uses a piston mechanism to deliver much harder impacts, making it ideal for drilling larger holes or for extended use in hard concrete. They are often used for demolition tasks as well.
- Diamond Core Drills: For very hard materials or when you need precise, large-diameter holes (like for plumbing or electrical conduits), diamond core drills are used. These are specialized, often wet-drilling systems.
- Professional Help: For major concrete work or if you’re uncomfortable with power tools, hiring a professional is always a good option.
While a hammer drill is the most common and accessible tool for DIYers, understanding these alternatives can be helpful for larger or more demanding projects.
Frequently Asked Questions (FAQ)
Q1: Can I use my regular drill to hang a picture on a concrete wall?
A1: No, not effectively. You’ll need a hammer drill and a masonry bit to create a proper hole for a wall anchor or screw in concrete. A standard drill will likely just spin without making progress.
Q2: What happens if I try to drill concrete with a regular drill bit?
A2: The regular drill bit will likely overheat, become dull very quickly, and may even break. You won’t be able to make a significant hole in the concrete, and you risk damaging your drill and the bit.
Q3: How do I know if my drill is a hammer drill?
A3: Look for a switch or dial on the drill body that has two symbols: one that looks like a drill bit and another that looks like a hammer. If it has the hammer symbol, it’s a hammer drill.
Q4: What size masonry bit do I need?
A4: The size of the masonry bit depends on what you are trying to attach. For most wall anchors, the anchor packaging will specify the required drill bit diameter. If you’re unsure, measure the diameter of the anchor you plan to use.
Q5: How deep should I drill into concrete?
A5: You should drill to the depth recommended for the anchor or screw you are using. Most anchors require a hole that is slightly deeper than the anchor itself to allow for dust and proper expansion.
Q6: Can I use a cordless drill for concrete?
A6: Yes, many cordless drills are now powerful enough to function as hammer drills. Just ensure it has the hammer drill function and is paired with the correct masonry bit and sufficient battery power.
Conclusion
So, to wrap it all up: will a normal drill go through concrete? Only if it’s a hammer drill and you’re using the right masonry bit. A standard drill/driver, while excellent for wood and metal, simply isn’t equipped for the toughness of concrete. By understanding the difference between drill types, investing in the correct masonry bits, and following the safety and drilling steps outlined above, you can confidently tackle your concrete drilling projects.
Happy drilling!
