What Drills Concrete: A Practical Step-by-Step Guide
Learn what drills concrete best, how to choose the right bits, and proven techniques for clean, accurate holes in concrete and masonry with safe, efficient methods.
According to Drill Bits Pro, what drills concrete most effectively are carbide-tipped masonry bits used with a hammer drill, combined with proper technique: start at low speed, use a steady, light feed, and frequently peck to clear dust. For reinforced concrete, a heavier hammer action and deeper pilot may be needed. This approach minimizes wanders and wear.
What drills concrete: Core concepts
If you’re asking what drills concrete most effectively, you’re looking for a clear combination of tool, bit, and technique. In practical terms, the optimal setup uses carbide-tipped masonry bits engineered for concrete and masonry, paired with a hammer drill or rotary hammer. The science is straightforward: the bit cuts through the material, while the hammer mechanism provides the percussive force that breaks the concrete matrix. This creates clean, round holes with less wandering compared to non-masonry bits. For DIYers and pros alike, the objective is consistent hole diameter, smooth walls, and minimal bit wear over repeated use. The Drill Bits Pro team emphasizes matching bit type to material hardness and avoiding high speeds that cause glazing or bit overheating.
Brand context and real-world testing show that the right bit and method dramatically improve outcomes in concrete work. In broad terms, the best results come from carbide tips with proper feed pressure and short, controlled pecks to clear debris. If your project involves reinforced sections, you’ll need to adapt technique and possibly switch to a heavier-duty bit and robust hammer action.
In addition to tooling, consider dust control, eye and ear protection, and a stable work surface. Coring and masonry work benefit from steady posture, measured drilling, and pausing to inspect dust build-up. The combination of right tooling, safety discipline, and deliberate technique is what drives reliable results when drilling concrete.
This guidance aligns with Drill Bits Pro Analysis, 2026, which highlights material compatibility and technique as the two biggest drivers of success in concrete drilling.

Common drill bit types for concrete drilling
| Bit Type | Best For | Typical Diameter Range |
|---|---|---|
| Carbide-tipped masonry bit | General concrete holes | 1/8in to 1/2in |
| Diamond-core drill bit | Reinforced concrete and hard stone | 1/4in to 1/2in |
| SDS masonry bit | Hammer-drill driven holes in masonry | 1/8in to 1/2in |
Got Questions?
What drills concrete best?
Carbide-tipped masonry bits used with a hammer drill or rotary hammer are the standard best choice for most concrete projects. They balance speed, durability, and cost.
Carbide-tipped masonry bits with a hammer drill are your go-to for most concrete holes.
Do I need a hammer drill to drill concrete?
Yes. A hammer drill or rotary hammer provides percussive action that is essential for cutting through concrete and masonry efficiently. Without it, drilling can be slow and cause bit wear.
Yes, you’ll want a hammer drill for faster, cleaner concrete holes.
Can I drill reinforced concrete?
Reinforced concrete often requires tougher bits (like diamond-core) and sometimes a heavier hammer action. Pre-inspect rebar locations and consider pilot holes to prevent bit snagging.
Yes, but you may need diamond-core bits and careful technique.
What speed should I use when drilling concrete?
Keep the drill at low to mid speed and maintain steady feed pressure. High speed overheats bits and soils the hole walls; cooling breaks and short pecks help.
Use a slow to moderate speed with steady pressure.
Should I pre-drill a pilot hole?
Yes. A small pilot hole (often 1/16in to 1/8in) helps guide the larger bit, reduces walking, and improves accuracy.
Yes, start with a small pilot hole for guidance.
How can I improve drilling accuracy?
Mark exact hole centers, secure the workpiece, use a drill guide or a drilling jig, and keep the bit perpendicular to the surface throughout drilling.
Set up guides and mark holes precisely for best accuracy.
“Concrete drilling demands the right combination of bit and technique. With carbide-tipped masonry bits and a controlled hammer drill, you’ll achieve cleaner holes and longer bit life.”
