Drilling into concrete or masonry isn’t just about having the right drill — the drill bit matters just as much. Even a powerful hammer drill will struggle or fail if the wrong bit is used.
This guide is for homeowners and DIY users who want clean, accurate holes in concrete, brick, or masonry without damaging tools, wasting time, or breaking bits. Below, you’ll learn which drill bits work best, how they differ, and how to avoid common mistakes.
What Type of Drill Bits Are Best for Concrete?
Masonry drill bits are the correct choice for drilling into concrete and masonry.
These bits are specifically designed to handle hard, abrasive materials. They feature a hardened tip that crushes concrete rather than cutting it like a wood or metal bit.
If you are unsure whether your drill setup is suitable for concrete in the first place, it’s important to understand which drill types are appropriate before choosing bits. A standard drill can work in limited cases, but it has clear limitations when paired with masonry bits.
Can a Regular Drill Drill Into Concrete?
Masonry Drill Bits Explained
Masonry drill bits are easily identified by their carbide tip, which is brazed onto the end of the bit.
Key characteristics:
- Hardened carbide tip
- Designed for impact and hammer action
- Available in many diameters and lengths
- Compatible with hammer drills and rotary hammers
These bits work best when paired with a hammer drill, which provides the impact force needed to break concrete efficiently. If you’re deciding between drill types, understanding the difference between hammer drills and rotary hammers helps ensure bit compatibility.
Hammer Drill vs Rotary Hammer: What’s the Difference?
Standard Masonry Bits vs SDS Bits
Not all concrete drill bits are the same. The two most common types are standard masonry bits and SDS bits.
Standard Masonry Drill Bits
- Fit regular drill chucks
- Used with hammer drills or regular drills
- Ideal for small to medium holes
- Common for homeowner projects
SDS Drill Bits
- Designed for rotary hammers
- Lock into the drill using a slotted shank
- Handle heavier impact forces
- Better for deep or repeated drilling
For most DIY tasks like installing anchors or mounting shelves, standard masonry bits are sufficient. SDS bits are typically used for more demanding jobs or frequent concrete drilling.
Choosing the Right Size Drill Bit
Choosing the correct bit size is critical for secure anchors and clean holes.
Tips for sizing:
- Match the bit size to the anchor diameter
- Do not oversize the hole
- Check manufacturer recommendations for anchors
- Use longer bits for deeper holes only when necessary
Using a bit that’s too large can weaken anchor hold, while a bit that’s too small may crack masonry or break the bit.
Can You Use Wood or Metal Bits on Concrete?
No. Wood and metal drill bits are not designed for concrete.
Using the wrong bit can cause:
- Rapid dulling
- Overheating
- Bit breakage
- Damage to the drill
Concrete requires crushing force, not cutting edges. Always use masonry-rated bits for brick, block, or concrete surfaces.
How to Make Masonry Drill Bits Last Longer
Concrete is abrasive, and poor technique shortens bit life.
Best practices:
- Drill at controlled speed
- Let the drill do the work
- Avoid excessive pressure
- Pull the bit out occasionally to clear dust
- Allow the bit to cool between holes
Using proper drilling technique also depends on selecting the right drill for concrete work. If you haven’t already, understanding which drill works best for concrete walls helps prevent unnecessary wear on bits and tools.

Common Mistakes When Using Concrete Drill Bits
Many drilling issues come from avoidable errors.
- Using the wrong type of bit
- Drilling without hammer mode enabled
- Applying too much force
- Drilling at high speed
- Skipping dust clearing during drilling
Avoiding these mistakes results in cleaner holes, better anchor grip, and longer bit lifespan.
Frequently Asked Questions
Do masonry drill bits require a hammer drill?
They work best with hammer drills, but can be used carefully with regular drills for soft masonry.
How long do concrete drill bits last?
Lifespan depends on material hardness, drilling technique, and cooling. Proper use extends life significantly.
Can masonry bits drill through rebar?
No. Hitting rebar requires specialized bits and techniques. Stop drilling if metal resistance is felt.
Should I use water when drilling concrete?
For most DIY drilling, no. Dry drilling with dust clearing is sufficient.
Are longer drill bits weaker?
Longer bits can flex more. Use the shortest bit that meets your depth requirement.
Conclusion
Drilling into concrete and masonry requires more than just power — it requires the right drill bit. Masonry drill bits are specifically designed to handle the hardness and abrasiveness of concrete, making them essential for safe and effective drilling.
By choosing the correct bit type, matching it to the right drill, and using proper technique, homeowners and DIY users can drill clean, accurate holes with less effort and fewer broken tools.
