Hammer Drill vs Impact Drill for Concrete: My Honest Experience
Drilling into concrete is no joke. I found this out the hard way while trying to hang a heavy-duty garage shelf on a block wall. My trusty impact driver gave up halfway through the first hole—and I was left wondering if I had the wrong tool altogether.
So, I did my homework. And if you're wondering "hammer drill vs impact drill for concrete – which one should I use?", you’re in the right place. In this article, I’ll walk you through:
-
The key differences between these two tools
-
Which one truly performs better for drilling concrete
-
Tips from my own experience
-
Mistakes to avoid if you're just starting out
Let’s break it down.
🔨 What’s the Difference Between a Hammer Drill and an Impact Drill?
Before we jump into performance on concrete, let’s clarify how these tools work.
Hammer Drill: The Concrete Killer
-
Action: Combines rotary motion with a hammering action that pushes forward into masonry.
-
Best For: Brick, concrete, cinder blocks.
-
Feels Like: A mini jackhammer in your hands.
Impact Drill (aka Impact Driver): The Torque Master
-
Action: Uses high torque bursts to drive screws or bolts, not forward hammering.
-
Best For: Driving long screws or bolts into wood or metal.
-
Feels Like: A power boost when tightening stubborn screws.
✅ Verdict: An impact drill is not designed for concrete. It lacks the forward hammering motion needed to break through tough masonry surfaces.
🧱 Hammer Drill vs Impact Drill for Concrete: Real-World Test
I tested both drills on a concrete basement wall while installing shelves and pipe clamps. Here's what happened:
Impact Drill Test:
-
Bit Used: Masonry bit
-
Time to Drill 1 Hole (¼” depth): 2 minutes+
-
Outcome: Bit kept slipping, concrete smoked, progress stalled.
Hammer Drill Test:
-
Bit Used: Same masonry bit
-
Time to Drill 1 Hole: 20–30 seconds
-
Outcome: Clean, precise hole with minimal effort.
The difference was night and day.
🛠️ Key Features to Look for in a Hammer Drill for Concrete
When shopping for a hammer drill, make sure it includes:
-
✅ Variable Speed Control – Crucial for better precision.
-
✅ Depth Gauge – Prevents overdrilling.
-
✅ Side Handle – Adds stability for tougher jobs.
-
✅ Corded or High-Powered Cordless – Concrete eats battery life fast.
👉 I personally use the DeWalt 20V MAX Hammer Drill (affiliate link) and it's held up perfectly for home renovations and garage work.
🧪 Durability and Ease of Use
-
Hammer Drill: Heavier, louder, but specifically made for this kind of work.
-
Impact Drill: Lightweight, easy for everyday tasks, but not tough enough for masonry.
If you’re doing any serious drilling into concrete, a hammer drill is worth the investment.
💡 Quick Comparison Table
| Feature | Hammer Drill | Impact Drill |
|---|---|---|
| Best Use | Drilling concrete/masonry | Driving screws/bolts |
| Drilling Concrete | ✅ Excellent | ❌ Poor |
| Torque | Moderate | High (rotational only) |
| Weight | Heavier | Lighter |
| Versatility | Masonry + wood | Fasteners only |
| Price Range | $70–$150 | $50–$100 |
🧼 Tips for Drilling Concrete Like a Pro
-
Start with a pilot hole using a smaller masonry bit.
-
Keep your drill perpendicular to avoid slipping.
-
Use water or take breaks to avoid overheating bits.
-
Mark your drilling depth with painter's tape on the bit shaft.
⚠️ Common Mistakes to Avoid
-
❌ Using an impact drill thinking “torque = power”
-
❌ Not using a masonry bit
-
❌ Drilling into wet or crumbly concrete without checking surface integrity
-
❌ Not wearing goggles – yes, concrete dust is a real hazard
FAQs: Hammer Drill vs Impact Drill for Concrete
What happens if I use an impact drill on concrete?
It may start the hole but likely won’t get far. You risk damaging the bit, overheating the tool, and making a mess of the wall.
Can I drill concrete with a regular drill?
Only if it's a hammer drill. A standard drill (without hammer function) will struggle or fail completely on concrete.
Is a hammer drill worth buying for one project?
If you're doing more than one or two holes, yes. Otherwise, check if your local hardware store rents them.
What's the best bit for concrete drilling?
Carbide-tipped masonry bits. SDS bits are ideal if your hammer drill is SDS-compatible.
Can I use the same drill for wood and concrete?
Some hammer drills have dual modes (rotary + hammer), making them versatile. Just switch off the hammer function when drilling wood.
💬 Final Thoughts + Call to Action
If you’re dealing with concrete, don’t settle for the wrong tool. I made that mistake—and wasted time, energy, and a good bit. A hammer drill is absolutely the way to go for clean, easy concrete drilling.
