How to Drill on Drywall: A Practical Guide
Learn how to drill on drywall safely and securely. This step-by-step guide covers stud locating, bit selection, anchors, and finishing for clean, secure mounting.
This guide shows you how to drill on drywall safely and cleanly. Learn to locate studs, choose the right bit, set the correct drill speed, and anchor securely without damaging surrounding material. By following these steps, you’ll mount lightweight shelves or fixtures with confidence. We cover tool selection, drilling technique, and aftercare to prevent wall damage.
Why drywall drilling requires careful technique
Drywall is a lightweight, layered material that can crack or crumble if you push too hard or use the wrong bit. Going too fast or choosing an oversized hole can create ragged edges and weak holds. According to Drill Bits Pro, drywall damage is often the result of rushing through a boring process or relying on a single method for every wall. A thoughtful approach—from planning to finishing—protects the wall, reduces repair work, and improves the security of what you mount. When you drill with intention, you preserve stud locations, minimize dust, and maintain the aesthetic of the room. This section explains why careful technique matters and how small choices—like bit type and speed—affect the final result.
Tools and materials you’ll need
Before you start, gather a few essentials so you don’t pause mid-project. A cordless drill with adjustable speed keeps control, while a sharp drywall bit or a sharp masonry bit (for anchors in some walls) ensures clean holes. Have a stud finder to locate framing, a pencil for marking, masking tape to guide the drill, and a few wall anchors sized for your screws. Keep safety gear handy—eye protection and a dust mask help protect you from drywall dust. Finally, have a small vacuum or dust pan ready to clean up. Using the right tools minimizes wandering, reduces wall damage, and makes the job faster and cleaner.
Understanding drywall structure and why it matters
Drywall consists of gypsum core sandwiched between paper faces. Behind the skin, there may be studs—solid wood or metal—providing the strongest mounting points. Anchors are used when you don’t hit a stud. Knowing whether you’re drilling into drywall alone or into a stud changes your approach: studs offer solid support for heavier loads, while anchors are needed for lighter items or when mounting on hollow sections. If you hit a stud, you can drive screws directly; if not, you’ll rely on anchors designed for drywall. Understanding this structure helps you choose the right strategy for each spot and avoids over- or under-engineering the mount.
Planning your drill: placement, anchors, and tools
Planning reduces misdrilled holes and wasted material. Start by marking the exact location with a pencil, then apply a piece of masking tape to the drill point to prevent wandering. Decide whether you will anchor into a stud or use drywall anchors. If you’re placing multiple holes, lay out the pattern on a level line and measure from nearby edges to maintain alignment. Confirm there are no electrical cables or hidden pipes behind the intended holes by using a cable detector or verifying wall plans if available.
Techniques for clean holes and secure anchors
A clean hole starts with a sharp bit and light, steady pressure. Begin drilling at a low speed to establish a clean entry and avoid tearing. If you plan to anchor into drywall without a stud, choose a tested drywall anchor and follow its recommended hole size. For pilot holes, start with a smaller bit size and gradually step up as needed to accommodate the anchor. Dust and debris can clog the hole, so wipe the area as you progress and re-check alignment before inserting anchors. These practices minimize wall damage and improve holding strength.
Securing with anchors and fasteners
When you don’t hit a stud, drywall anchors transfer load to the wall’s hollow core. Insert the anchor fully to sit flush with the surface, then drive the screw into the anchor until snug—avoid overtightening, which can crush drywall around the hole. If you hit a stud, you can drive a screw directly into it for greater load capacity. Always use a screwdriver to seat the screw after the drill has created the hole and ensure the item sits tightly against the wall.
Finishing, patching, and cleanup
After mounting, remove any masking tape and wipe away dust. If your hole is slightly oversized, you can use a touch of lightweight spackle to level the surface, then sand smooth after it’s dry. Repaint or touch up the area to restore a uniform finish. Clean up dust with a small vacuum, then wipe surrounding surfaces to keep the room tidy. Proper finishing helps make the installation look professional and reduces the likelihood of future repairs.

Tools & Materials
- Stud finder(Optional if you plan to anchor into studs; otherwise use drywall anchors)
- Drill with variable speed(Cordless preferred; set to low-to-medium speed)
- Drywall bit or self-centering bit(Sharp and carbide-tipped recommended)
- Pilot bit (optional)(3/32in or 1/8in depending on screw size)
- Screw anchors or wall plugs(Plastic anchors for hollow walls; choose size to match screw)
- Masking tape(Lightly mark drilling points to prevent wandering)
- Pencil, measuring tape, level(For precise location and alignment)
- Safety gear: safety glasses(Protect eyes from dust and debris)
- Dust collection or vacuum(Helps keep area clean and visible)
Steps
Estimated time: about 25-40 minutes
- 1
Mark the drilling locations
Use a pencil to mark the exact points. Place masking tape over the mark to minimize bit wandering and ensure a clean entry.
Tip: Double-check height and alignment with a level before drilling. - 2
Locate studs or plan anchors
If mounting near a wall stud, plan for direct screw mounting into the stud. Otherwise, mark where you’ll place drywall anchors.
Tip: A stud finder helps confirm stud locations behind the drywall. - 3
Select and prepare your bit
Choose a bit appropriate for drywall and your anchor type. Inspect for burrs and ensure the bit is sharp.
Tip: A sharp bit reduces ragged edges and makes inserting anchors easier. - 4
Drill the pilot hole
Begin with a small pilot hole at the marked location to reduce the risk of cracking or wandering.
Tip: Keep the drill steady and perpendicular to the wall. - 5
Drill the final hole and insert anchor
Open the hole to the final size required by the anchor, then insert the anchor flush with the surface.
Tip: If it doesn’t sit flush, remove and re-seat at the correct size. - 6
Drive in the screw
Thread the screw into the anchor or into the stud until snug. Do not overtighten.
Tip: Use a screwdriver to control the final seating pressure. - 7
Mount your fixture
Position the fixture and secure with screws. Check for levelness and stability.
Tip: Re-check alignment after the first few screws are installed. - 8
Finish and clean
Remove masking tape, patch any small holes if needed, and clean up dust.
Tip: Touch up with paint to match surrounding walls.
Got Questions?
Do I need to locate studs before drilling into drywall?
Yes. Locating studs provides a solid mount for heavier items and reduces the risk of the screw pulling out. If you can’t hit a stud, use appropriate drywall anchors designed for load bearing.
Yes, locating studs gives you strong mounting points. If there is no stud, use suitable drywall anchors.
Can I drill directly into drywall without a stud?
You can, but you should use a proper drywall anchor or plug to transfer the load to the wall. For light items, light-duty anchors work well; for heavier items, use multi-part anchors or toggle bolts.
You can, but use anchors appropriate to the weight you’re mounting.
What size drill bit should I use for drywall anchors?
Follow the anchor package instructions for the correct hole size. If in doubt, start with the smallest pilot hole and test with the anchor.
Use the size recommended on the anchor package and test fit.
What should I do if I hit electrical wiring behind drywall?
Stop drilling immediately, don’t move the drill, and move to another location. Use a stud finder with live-wire detection or a qualified professional if you’re unsure.
If you hit a wire, stop and move to a new location. Check with appropriate detectors.
How can I patch drywall after drilling a hole?
Fill small holes with lightweight spackle, let it dry, sand smooth, and repaint. For larger holes, apply drywall repair mesh and compound before sanding and painting.
Patch with spackle, sand, and repaint. For big holes use a patch and compound.
What drill speed is best for drywall?
Use low to medium speed to maintain control and reduce edge tearing. Quick bursts can cause the bit to skip and damage the surface.
Drill slowly and steadily for clean holes.
