How to drill into stucco?

Stucco walls are durable, long-lasting, and relatively easy to maintain. However, drilling into stucco walls can be a bit tricky, especially if you are not familiar with the process. Now, l we will discuss the steps involved in drilling into stucco with a drill bit. We will also provide some tips and tricks to make the process easier and safer.


1. What you should prepared?

The first thing in drilling into stucco is to choose the right drill bit. The most common types of drill bits used for stucco are Wet diamond Core Drill Bits, Crown Diamond Core Bits, and Dry Diamond Core Drill Bits. Wet diamond Core Drill Bits are the most affordable and are suitable for drilling small holes in stucco.

  • Tape measure

Use a tape measure to measure and mark the spot where you need to drill the hole.

  • Pencil or marker

Use a pencil or marker to make a small mark on the stucco where you need to drill.

  • Level

A level is useful for ensuring that the hole you drill is straight and level.

  • Dust mask

Drilling into stucco can generate a lot of dust. It is important to wear a dust mask to protect your lungs.

  • Safety glasses

Wear safety glasses to protect your eyes from dust and debris.

  • Vacuum or brush

Use a vacuum or brush to clean the area where you will be drilling and to remove dust as you drill.

  • Anchors and screws

If you are installing a screw or fastener into the hole, you will need anchors to provide additional support.


2. Steps to drill into stucco with drill bit

Step 1: Prepare the Surface

Before you begin drilling, you need to prepare the surface of the stucco. This involves cleaning the area where you will be drilling and removing any debris or loose stucco. Use a wire brush to clean the area and a vacuum to remove any dust or debris.

Step 2: Mark the Hole

Once the surface is clean, you can mark the spot where you want to drill the hole. Use a pencil or a marker to make a small mark on the stucco. Make sure the mark is centered and level.

Step 3: Secure the Stucco

To prevent the stucco from cracking or breaking while you drill, you need to secure it in place. You can do this by using a piece of duct tape or painter’s tape. Place the tape over the area where you will be drilling, and make an “X” over the mark you made in step 2. This will help to prevent the stucco from chipping or cracking while you drill.

Step 4: Drill the Hole

Now it’s time to drill the hole. Put the drill bit into the drill and set the drill to a slow speed. Hold the drill straight and perpendicular to the surface of the stucco. Apply steady pressure and begin drilling. Do not push too hard or drill too fast, as this can cause the stucco to crack or chip.

Step 5: Remove the Dust

As you drill, you will generate a lot of dust. To prevent the dust from clogging up the hole, you need to remove it regularly. Use a vacuum or a brush to remove the dust from the hole as you drill. This will also help you to see the progress of the drilling.

Step 6: Finish the Hole

Once you have drilled the hole to the desired depth, remove the drill bit from the hole. Use a brush or a vacuum to remove any remaining dust or debris. You can also use a wire brush to smooth the edges of the hole.

Step 7: Install the Anchor

If you are installing a screw or a fastener into the hole, you will need to install an anchor first. The anchor will provide additional support and prevent the screw from slipping or coming loose. Follow the instructions on the anchor packaging to install it properly.


Q & A about drilling into stucco

Q: What kind of drill bit do I need for drilling into stucco?

A: You will need a masonry drill bit that is designed to drill through hard surfaces like concrete, brick, and stucco. Look for a Wet diamond Core Drill Bits that is the right size for the screws or anchors you will be using.

Q: What speed should I use when drilling into stucco?

A: Use a low speed setting on your drill when drilling into stucco to avoid damaging the surface. Apply light pressure and allow the drill bit to do the work.

Q: What should I do if I accidentally crack or damage the stucco surface while drilling?

A: If you accidentally damage the stucco surface while drilling, you can use a stucco repair patching material to fill in the crack or hole. Apply the patching material according to the drill bits manufacturer‘s instructions and allow it to dry completely before painting or finishing the surface

Q: How do I know if I’m drilling into a stud or a hollow area behind the stucco?

A: To determine whether you are drilling into a stud or a hollow area behind the stucco, use a stud finder or wire detector. These tools will help you locate any electrical wiring or plumbing behind the wall, as well as the position of the studs. If you are drilling into a hollow area, you will need to use a wall anchor or toggle bolt to secure the screw.

Q: How deep should I drill into stucco?

A: The depth of the hole you drill into stucco will depend on the length of the screw or anchor you are using. As a general rule, the hole should be slightly deeper than the length of the screw or anchor, to ensure a secure hold.

Q: Can I paint over the hole after I’ve drilled into stucco?

A: Yes, you can paint over the hole after you’ve drilled into stucco. However, you should wait until any caulk or stucco patching material has dried completely before painting. Once the surface is dry, you can paint it to match the surrounding stucco.

Q: How to maintain my drill bits?


  1. Clean the bit after use: Once you’re done drilling, use a soft brush or cloth to clean any dust or debris off the drill bit. This will help prevent buildup and maintain the bit’s sharpness.
  2. Keep the bit sharp: Use a sharpening stone or a drill bit sharpener to keep the bit sharp. Dull bits can cause the drill to work harder, leading to overheating and reducing the lifespan of the bit.
  3. Lubricate the bit: Apply a small amount of lubricant to the bit to reduce friction and prevent overheating. This can also help extend the life of the bit.
  4. Store the bits properly: Store your drill bits in a clean, dry place, away from moisture and extreme temperatures. You can use a drill bit storage case or a hanging rack to keep them organized and easily accessible.
  5. Replace worn or damaged bits: Over time, drill bits can become worn or damaged, and it’s important to replace them to maintain optimal performance. Signs that a drill bit needs to be replaced include dullness, chipping or cracking, and difficulty drilling into the surface.



Drilling into stucco is not as challenging as it may seem. With the right tools, techniques, and precautions, you can successfully drill into stucco without causing any damage. Remember to protect the surrounding area with masking tape, wear protective gear, and pull out the drill bit occasionally to remove dust. By following these steps, you can drill into stucco safely and effectively.
