How to Drill Into Concrete

Drilling into concrete is one of the more challenging DIY tasks — but with the right tools and technique, it's completely manageable. Whether you're anchoring a shelf bracket, mounting a TV on a concrete wall, or installing a fence post, this guide covers everything you need to know.

What You'll Need

• Hammer drill or rotary hammer — a regular drill won't cut it for concrete
• Masonry drill bits — carbide-tipped
• Safety goggles and work gloves
• Dust mask — concrete dust is harmful to lungs
• Concrete anchors or sleeve anchors

Choosing the Right Drill for Concrete

A standard cordless drill can handle light concrete work, but for anything thicker than 1 inch, you need a hammer drill or rotary hammer:

• BLACK+DECKER Hammer Drill (BEHD201) — 6.5-Amp, 1/2-inch, great for occasional concrete drilling. Check it on Amazon →
• DEWALT SDS Rotary Hammer Drill (D25263K) — Professional-grade with vibration control, ideal for heavy concrete and block work. Check it on Amazon →

Choosing the Right Masonry Bit

Always use carbide-tipped masonry bits for concrete. The DEWALT Masonry Drill Bit Set (DW5207) is a 7-piece percussion set designed specifically for concrete and block — reliable and long-lasting. Check it on Amazon →

Step-by-Step: How to Drill Into Concrete

1. Mark your spot with a pencil or chalk.
2. Put on safety gear: goggles, gloves, and a dust mask. DEWALT Safety Goggles → | HANDLANDY Work Gloves →
3. Start with a small pilot hole (3mm or 1/8") to guide your larger bit.
4. Set your drill to hammer mode (the hammer icon on the mode selector).
5. Begin at low speed to establish the hole, then increase.
6. Apply firm, steady pressure — don't force it, let the hammering action do the work.
7. Pull back periodically to clear concrete dust from the hole.
8. Use tape on the bit as a depth guide to avoid drilling too deep.
9. Clear the hole with a brush or compressed air before inserting anchors.

Tips for Drilling Into Hard Concrete

• If the bit stops making progress, you may have hit rebar — move your hole slightly
• Keep the bit cool by occasionally dipping it in water (for corded drills)
• Use a fresh, sharp bit — dull masonry bits are the #1 cause of failed concrete drilling
• For very hard concrete, upgrade to an SDS rotary hammer

Safety Reminders

• Concrete dust contains silica — always wear a dust mask or respirator
• Wear safety goggles — chips and dust fly back at high speed
• Check for embedded rebar or conduit before drilling in structural walls
• Never drill near electrical conduit without confirming its location

Common Mistakes to Avoid

• Using a regular drill instead of a hammer drill
• Using wood or metal bits on concrete
• Not clearing dust from the hole
• Drilling too fast and overheating the bit
• Skipping the pilot hole on hard concrete
